It is noted that chip frequency modulation technology of the present invention is practical to be related to the frequency Regulation mechanism of two levels: operation chip
Frequency Regulation mechanism and kernel level frequency Regulation mechanism.The frequency Regulation mechanism of the operation chip refers to for each fortune
It calculates chip and several suitable working frequency points is set, and each kernel 50 of operation chip is allowed to work in each working frequency points, sufficiently
Play the working performance of each kernel 50.The frequency Regulation mechanism of the kernel level refers to computational according to the reality of kernel 50
Can, kernel 50 is adjusted to suitable working frequency points, it is low to lower calculated performance for the frequency of the high kernel 50 of up-regulation calculated performance

It can may be not enough to operation at frequencies corresponding in current working frequency.
The frequency regulation block 30, if the current value for kernel 50 reaches scheduled calculating proper threshold value, by kernel
50 current working frequency is raised；If alternatively, reach scheduled calculating error thresholds for the current value of kernel 50, will in
The current working frequency of core 50 is lowered.It, will be according to the practical meter of kernel 50 i.e. according to the frequency Regulation mechanism of kernel level
Performance is calculated, kernel 50 is adjusted to suitable working frequency points, the frequency of the high kernel 50 of up-regulation calculated performance lowers calculated performance

It is that frequency adjusting submodule 31 is raised or lowered by current working frequency of the phase-locked loop circuit 40 to kernel 50.Certainly,
Frequency adjusting submodule 31 can also by other hardware or software realization to the current working frequency of kernel 50 carry out up-regulation or
It lowers.
The stop frequency adjusting submodule 32, if the kernel for working at least one scheduled Optimization Work frequency point
50 be more than scheduled first ratio, stops carrying out frequency modulation to kernel 50；If for working in an at least Optimization Work frequency point
On kernel 50 number it is most, stop to kernel 50 carry out frequency modulation.
For example, default one or more Optimization Work frequency points can be selected in several working frequency points, if most of kernels 50
Working frequency have arrived at the Optimization Work frequency point, show in operation chip that the working frequency of kernel 50 has been in optimization
State can give full play to the calculated performance of each kernel 50, it is no longer necessary to further frequency modulation, therefore stop 50 working frequency of kernel
Adjustment.Such as 6 working frequency points of setting, 500MHz, 550MHz, 600MHz, 650MHz, 700MHz, 750MHz, selection is wherein
Two Optimization Works frequency point 600Mhz and 650Mhz are Optimization Work frequency point, if being more than that 80% kernel 50 works in working frequency points
600Mhz and 650Mhz then stops carrying out frequency modulation to kernel 50.

Device 100 includes frequency point setting module 10, calculated performance analysis module 20, frequency regulation block 30, in which:
The frequency point setting module 10, for the multiple working frequency points of operation chip setting to calculate equipment, each work
The frequency of frequency point is different, and multiple kernels 50 in operation chip are worked in each working frequency points respectively.I.e. according to operation chip
Frequency Regulation mechanism, several different frequency points are set for each operation chip, and each kernel 50 of operation chip is allowed to work
In each working frequency points.Such as 6 working frequency points of setting: 500MHz, 550MHz, 600MHz, 650MHz, 700MHz, 750MHz.
Gap can be arranged according to actual needs between the frequency points of working frequency points of the present invention, frequency, and the working frequency points the more more can be abundant
Play the calculated performance of each kernel 50.When starting frequency modulation switch (not yet to kernel 50 carry out frequency modulation), kernel 50 can be by
It is averaged distribution, unequal distribution according to pre-defined rule or is randomly distributed in the working frequency points and work.Preferably, frequency point is set
Setting module 10 can be that multiple working frequency points are arranged in operation chip by multiple phase-locked loop circuits 40 as shown in Figure 2.
The calculated performance analysis module 20 further comprises having:
Submodule 22 is set, for presetting the reference node point value of kernel 50, calculating correct weighted value, calculating mistake power
Weight values calculate proper threshold value and calculate error thresholds.It is described calculate correct weighted value and calculate error weight value can it is identical or
It is not identical；The calculating proper threshold value and calculating error thresholds can be identical or not identical.The reference node point value calculates correctly
Weighted value, calculating error weight value, calculating proper threshold value and calculating error thresholds belong to adjustable parameter, can be adjusted according to frequency
The actual needs such as speed optimize setting.
Submodule 21 is analyzed, it is whether correct in each calculating of current working frequency for analyzing kernel 50.Kernel 50 can
To carry out a variety of different calculating, can analyze kernel 50 it is each certain or it is several calculate it is whether correct.Preferably analyze kernel
Whether 50 calculated Nonce are correct.
Counting submodule 23 is often computed correctly at least once for kernel 50, increases primary calculate on reference node point value
Correct weighted value, and the every erroneous calculations of kernel 50 are at least once, and primary calculating error weight value is reduced on reference node point value.
Preferably, kernel 50 is often computed correctly once, is increased on reference node point value and is once calculated correct weighted value.Of course, it is possible to
It is set as kernel 50 and is often computed correctly n times (N is the natural number greater than 1), increase the correct power of primary calculating on reference node point value
Weight values.The every erroneous calculations of kernel 50 are primary, and primary calculating error weight value is reduced on reference node point value.Of course, it is possible to be arranged
For the every erroneous calculations n times of kernel 50 (N is the natural number greater than 1), primary calculating error weight value is reduced on reference node point value.
Judging submodule 24 calculates proper threshold value or calculating for judging whether the current reference nodal value of kernel 50 reaches
Error thresholds.If current reference nodal value reaches calculating proper threshold value, then it represents that the calculated performance of the kernel 50 is higher and can
It can be there are also room for promotion；If current reference nodal value reaches calculating error thresholds, then it represents that the calculated performance of the kernel 50 compared with
It is weak, operation at frequencies corresponding in current working frequency may be not enough to.
The frequency regulation block 30 shows if the current reference nodal value for kernel 50 reaches calculating proper threshold value
Optimal computed performance has not yet been reached in the kernel 50, and the current working frequency of kernel 50 is raised；And if being used for kernel 50
Current reference nodal value reach calculating error thresholds, show that the calculated performance of the kernel 50 is not enough in current working frequency
Work, the current working frequency of kernel 50 is lowered.Preferably, the frequency regulation block 30 can pass through such as Fig. 2 institute
The phase-locked loop circuit 40 or software shown carries out frequency modulation to kernel 50.It will be appreciated by persons skilled in the art that frequency point adjusts mould
The adjustment mode of the adjustment setting working frequency points of block 50 is not limited to that.It, will i.e. according to the frequency Regulation mechanism of kernel level
According to the practical calculated performance of kernel 50, kernel 50 is adjusted to suitable working frequency points, the high kernel 50 of up-regulation calculated performance
Frequency, the frequency of the low kernel 50 of calculated performance is lowered, to give full play to the calculated performance of each kernel 50.
Preferably, if current value of the frequency regulation block 30 for kernel 50 reaches calculating proper threshold value, by kernel 50
Current working frequency on be transferred to a working frequency points；If the current value for kernel 50 reaches calculating error thresholds,
The current working frequency of kernel 50 is lowered to next working frequency points.It will be appreciated by persons skilled in the art that upper one
Working frequency points are not limited in upper operated adjacent frequency point, may also set up more than one upper operated adjacent frequency point as upper one
A working frequency points；Next working frequency points are not limited in next operated adjacent frequency point, may also set up more than one next phase
Adjacent working frequency points are as next working frequency points.As, a upper work will be transferred on the current working frequency 600MHz of kernel 50
Make frequency point 700MHz；The current working frequency 600MHz of kernel 50 is lowered to next working frequency points 500MHz.And so on,
Herein not to a upper working frequency points, the spacing of subsequent work frequency point is limited.Preferably, current working frequency and a upper work
Make that the frequency difference between frequency point is 1~10% and the frequency difference of current working frequency and next working frequency points is 1~10%, makes
Kernel 50 when being transferred to a upper working frequency points or next working frequency points from current working frequency, the calculated performance of kernel 50
Benefited should be greater than losing.
For example, setting 400000 is used as reference node point value, calculates correct weighted value and be set as 180, calculates error weight value and set
It is 9000, calculates proper threshold value and calculating error thresholds are set as 100000.
Kernel 50 is often computed correctly once, and 180 (calculating correct weighted value) are added on the reference node point value；The every mistake of kernel 50
Error count calculates primary, reduction 9000 (the calculating error weight values) on the reference node point value；On the basis of the reference node point value, often
Increase or decrease 100000 (calculate proper threshold value and calculate error thresholds), a upward frequency point is advanced or to next frequency point depression of order.
Present scheme is similar to mistake and correct tug-of-war mechanism, and correct and mistake can have different weights.If
Reference node point value is set, a correct result is often received, increase once calculates correct weighted value, often receives an error result, subtract
Few primary calculating error weight value carries out the up-regulation or downward of frequency if reward or punishment are more than respective side thresholding.It can be with
Understanding that adjustment system has a marker, reference node point value is the initial value of maker, if there is correctly submitting then maker+180,
Mistake submits then maker -9000 every time.Correct (N is the natural number more than or equal to 1) by n times, (M is big after M mistake
In or equal to 1 natural number), marker should be in the position of 400000+N*180-M*9000, if Marker be more than certain side
Thresholding then carries out corresponding frequencies adjustment (raise or lower).Then every secondary frequencies are adjusted on new frequency point that all initialization should
Current reference nodal value, i.e., is re-set as initial reference node point value by value.
Preferably, the setting submodule 22 is for being arranged according to actual needs and adjusting the reference mode of kernel 50
It is worth, calculates correct weighted value, calculate error weight value, calculate proper threshold value and/or calculate error thresholds, calculates correct weighted value
Calculating proper threshold value identical perhaps not identical with calculating error weight value and calculating error thresholds are identical or not identical.
Preferably, the setting submodule 22 is used to calculate correct weighted value by control and calculates error weight value
The resident error rate of the expectation tolerance of Ratio control kernel 50.The calculation formula of resident error rate are as follows: resident error rate=calculating is just
True weighted value/(calculating correct weighted value+calculating error weight value).
Preferably, the setting submodule 22 is used to calculate correct weighted value by control and calculates error weight value
The order of magnitude control adjustment period.
Preferably, the setting submodule 22 is used to calculate proper threshold value by control and calculates the absolute of error thresholds
It is worth the size control adjustment period.
Preferably, being computed correctly for the kernel 50 refers to that kernel 50 is computed correctly Nonce.
The analysis submodule 21, it is whether correct for analyzing the Nonce that kernel 50 is submitted every time.
The counting submodule 26, for increasing on reference node point value in the every submission correct Nonce at least once of kernel 50
Add and once calculates correct weighted value；And the every submission mistake Nonce at least once of kernel 50, it is reduced once on reference node point value
Calculate error weight value.Preferably, in the primary correct Nonce of every submission of kernel 50, increase primary meter on reference node point value
Calculate correct weighted value.It is of course also possible to be set as the every submission N of kernel 50 (N is greater than 1 natural number) secondary correct Nonce, joining
It examines to increase on nodal value and once calculates correct weighted value.Kernel 50 is every to submit primary mistake Nonce, reduces on reference node point value
It is primary to calculate error weight value.It is of course also possible to be set as the every submission N of kernel 50 (N is greater than 1 natural number) secondary mistake
Nonce reduces primary calculating error weight value on reference node point value.
It is preferred that analysis submodule 21 further comprises:
Computing unit 211, after submitting a Nonce for kernel 50, kernel 50 calculates Nonce by scheduled algorithm
First as a result, include fisrt feature in first result out.
Unit 212 is checked, for Nonce to be calculated second as a result, wrapping in second result by identical algorithm
Contain second feature.If fisrt feature is identical as second feature, determine that Nonce is correct Nonce, otherwise determines that Nonce is
Mistake Nonce.
For example, kernel 50 is submitted after calculating a Nonce, the first Kazakhstan is calculated in Nonce insertion block head
It wishes as a result, preceding 20 values of the first Hash result are 0 (fisrt feature).It checks unit 212 and the Nonce is also embedded in block head
The second Hash result is calculated, if first 20 of the second Hash result are also 0 (second feature), then it is assumed that the Nonce is
Primary correct submission.
It is noted that in order to improve single kernel 80 calculate can meet write-in block chain nonce value probability,
It can judge that Hash, each kernel 80 will be submitted using Target_Lite much easier than above-mentioned " target value Target "
Nonce can be more frequently submitted, the nonce that the first checking computations unit 212 submits kernel 80 is checked, if it is used
The calculated Hash of nonce that kernel 80 is submitted equally passes through the judgement of Target_Lite, that is, thinks correctly mentioning for kernel 80
It hands over, is otherwise that mistake is submitted.The invention is not limited to the nonce for using writable final block chain.First checking computations unit
The nonce of interaction is to meet more low threshold between 212 and kernel 80, submits density high, can be conducive to frequency and adjust.
In a concrete application embodiment of the invention: 6 phase-locked loop circuits 40 are used, 6 working frequency points are set:
500MHz, 550MHz, 600MHz, 650MHz, 700MHz, 750MHz.Such as it is arranged 400000 and is used as reference node point value, calculates correct
Weighted value is set as 180, calculates error weight value and is set as 9000, calculates proper threshold value and calculating error thresholds are set as 100000.
It is as follows that the number of cores being distributed in each respective frequencies that power plate counts is calculated according to 4 pieces:
Calculate power plate 0:[294 26 96 224 1,023 1665]
Calculate power plate 1:[274 47 111 212 963 1721]
Calculate power plate 2:[350 25 153 369 1,381 1050]
Calculate power plate 3:[488 33 184 367 1,342 950]
Firstly, combined data further illustrates mechanism.Correct weighted value/(calculate correct is calculated according to resident error rate S=
Weighted value+calculating error weight value), and by given data can extrapolate the resident error rate S of kernel 50 (being interpreted as can
Some frequency point is resided in for a long time) it is 180/ (180+9000)=1.29%, the permanent work of kernel 50 at this time is on some frequency point
(because expectation step-length is 0 at this time), working frequency will not be raised or be lowered.It can be deduced that if the calculating error rate of kernel 50 is big
In 1.29% (resident error rate S), working frequency will be raised；If the calculating error rate of kernel 50 is (resident less than 1.29%
Error rate S), working frequency will be lowered.
According to the difficulty being arranged, (difficulty is related with benchmark is examined, and calculates accuracy to kernel 50 and has an impact, degree-of-difficulty factor
Bigger, accuracy is lower；It is on the contrary then accuracy is higher), it can calculate the approximate period for making mistake and adjusting when rising, it is assumed that mistake
Rate is e, then the expectation step-length of each Nonce are as follows:
(1-e) * 180-e*9000=180-9180e.By taking e=0.5% as an example, it is expected that step-length=134.1；It is with e=1%
Example, it is expected that step-length=88.2；By taking e=2% as an example, it is expected that step-length=- 3.6.
By taking 650MHz as an example, kernel 50 submits 1.3/second that are desired for of single Nonce (to submit 1.3 within i.e. 1 second
Nonce).It is explained with the scene that e is 0.5%, i.e., after 746 Nonce submission processes, so that it may it is expected that adjusting upward
Once；E is 1.0% needs, 1134 submissions, it is contemplated that adjusts upward once, if error probability is 2.0%, needs 27778
Secondary submission, it is contemplated that adjustment is primary downwards, other are analogized.
Preferably, the calculated performance analysis module 20 is used for according to preset real-time adjustment instruction, in real-time judge
Whether the current reference node of core 50, which reaches, calculates proper threshold value or calculates error thresholds, and the calculating proper threshold value or calculating are wrong
Accidentally threshold value is identical or not identical.
The frequency regulation block 30 is used for for frequency regulation block 30 according to preset real-time adjustment instruction, if kernel
50 current reference node reaches calculating proper threshold value, in real time raises the current working frequency of kernel 50.If kernel 50
Current reference node reach calculating error thresholds, the current working frequency of kernel 50 is lowered in real time, so that kernel 50
Working frequency obtain in real time dynamic adjust.
Preferably, the calculated performance analysis module 20 is used to be instructed according to preset timing adjustment, in timing adjustment
In the adjustment time section for instructing setting, judges whether the current reference node of kernel 50 reaches and calculate proper threshold value or calculating mistake
Threshold value, the calculating proper threshold value or calculating error thresholds are identical or not identical.
The frequency regulation block 30 is used to be instructed according to preset timing adjustment, in adjustment time section, if kernel 50
Current reference node reach calculating proper threshold value, the current working frequency of kernel 50 is raised.In adjustment time section,
If the current reference node of kernel 50 reaches calculating error thresholds, the current working frequency of kernel 50 is lowered, so that interior
The working frequency of core 50 obtains timing adjustment.Go out correctly as set statistics kernel 50 in 24 hours that Saturday is only arranged weekly
The number of Nonce, and according to calculating accuracy making frequency adjustment.
Preferably, the calculated performance analysis module 20 analyzes kernel 50 for instant adjustment instruction based on the received
Current reference node whether reach calculate proper threshold value or calculate error thresholds, the calculatings proper threshold value or calculate mistake threshold
It is worth identical or not identical.
The frequency regulation block 30 is for instant adjustment instruction based on the received, if the current reference node of kernel 50 reaches
To proper threshold value is calculated, the current working frequency of kernel 50 is raised.If the current reference node of kernel 50 reaches calculating
Error thresholds lower the current working frequency of kernel 50.Stop adjustment instruction based on the received, stops to kernel 50
The adjustment of current working frequency.And for stopping adjustment instruction based on the received, stop the current working frequency to kernel 50

For example, user can send instant adjustment instruction, the every meter of user setting kernel 50 to calculating equipment at any time as needed
It is primary to calculate correct Nonce, increases weight A on reference mode, the every calculating mistake Nonce of kernel 50 is primary, in the reference mode
Upper reduction weight B.It is when current increase numerical value reaches calculating correct number threshold value C, the upward frequency point of kernel 50 is advanced.Currently subtract
When a small number of values reach calculating error number threshold value D, by kernel 50 to next frequency point depression of order.In addition, user can as needed at any time
Stop adjustment instruction to calculating equipment and sending, after calculating equipment receives the stopping adjustment instruction, stops the tune to kernel 50 immediately
Frequently.
The present invention also provides it is a kind of include calculation power plate just like the chip frequency modulation device 100.
The present invention also provides it is a kind of include the chip frequency modulation device 100 calculating equipment.
Fig. 4 is the flow chart for the chip frequency modulation method that the present invention calculates equipment, can pass through the chip for calculating equipment
Frequency modulation device 100 realizes that the calculating equipment includes at least one operation chip, and the operation chip is provided with multiple kernels.
The calculating equipment is preferred for magnanimity operation, such as the operation for excavating virtual digit currency.It is noted that of the invention
The practical frequency Regulation mechanism of two levels that is related to of chip frequency modulation technology: the frequency Regulation mechanism and inner nuclear layer of operation chip level
The frequency Regulation mechanism in face.The frequency Regulation mechanism of the operation chip level refer to for the setting of each operation chip it is several suitable
Working frequency points, and each kernel 50 of operation chip is allowed to work in each working frequency points, gives full play to the work of each kernel 50
Make performance.The frequency Regulation mechanism of the kernel level refers to the practical calculated performance according to kernel 50, and kernel 50 is adjusted to
Suitable working frequency points, the frequency of the high kernel 50 of up-regulation calculated performance, lower the frequency of the low kernel 50 of calculated performance, thus
Give full play to the calculated performance of each kernel 50.The method includes the steps have:
Multiple working frequency points are arranged to calculate the operation chip of equipment, by multiple kernels in operation chip in step S401
50 work in each working frequency points respectively.
Several different frequency points are arranged according to the frequency Regulation mechanism of operation chip for each operation chip in this step, and
Each kernel 50 of operation chip is allowed to work in each working frequency points.Such as 6 working frequency points of setting: 500MHz, 550MHz,
600MHz, 650MHz, 700MHz, 750MHz.Gap can be according to practical need between the frequency points of working frequency points of the present invention, frequency
It is arranged, the working frequency points the more more can give full play to the calculated performance of each kernel 50.(not yet internally when starting frequency modulation switch
Core 50 carries out frequency modulation), kernel 50 can be averaged distribution, unequal distribution according to pre-defined rule or be randomly distributed in the work
It works on frequency point.Preferably, this step can be that the setting of operation chip is more by multiple phase-locked loop circuits 40 as shown in Figure 2
A working frequency points, naturally it is also possible to which multiple working frequency points are arranged for operation chip by other hardware or software.
Step S402, whether analysis kernel 50 is correct in each calculating of current working frequency, and kernel 50 is often computed correctly
At least once, increase the primary scheduled correct weighted value of calculating, and the every erroneous calculations of kernel 50 are at least once, reduce primary pre-
Fixed calculating error weight value.
If the current value of kernel 50 reaches scheduled calculating proper threshold value, then it represents that the calculation of performance indicators of kernel 50 compared with
The calculated performance of height, the kernel 50 may be there are also room for promotion.If the current value of kernel 50 reaches the wrong threshold of scheduled calculating
Value, then it represents that the calculation of performance indicators of kernel 50 is lower, and the calculated performance of the kernel 50 may be not enough in work at present frequency
The corresponding operation at frequencies of point.
Step S403, if the current value of kernel 50 reaches scheduled calculating proper threshold value, by the work at present frequency of kernel 50
Point is raised；Alternatively, if the current value of kernel 50 reaches scheduled calculating error thresholds, by the current working frequency of kernel 50
It is lowered.
This step is according to the frequency Regulation mechanism of kernel level, by according to the practical calculated performance of kernel 50, by kernel
50 are adjusted to suitable working frequency points, and the frequency of the high kernel 50 of up-regulation calculated performance lowers the low kernel 50 of calculated performance
Frequency, to give full play to the calculated performance of each kernel 50.
The present invention evaluates the working performance of kernel 50 according to the practical calculated performance of kernel 50 each in operation chip, adjusts
50 respective frequencies of kernel, give full play to the calculating advantage of the more excellent kernel 50 of performance, and the weaker kernel 50 of performance is avoided to influence operation
The operational performance of chip utmostly plays the calculated performance of each kernel 50, and then raising operation chip and overall calculation are set
Standby calculating speed and calculating accuracy.Also, the kernel 50 of operation chip of the present invention will not change back and forth frequency, working frequency
It is relatively stable.
Preferably, the step S401 can be that multiple work frequencies are arranged in operation chip by multiple phase-locked loop circuits 40
Point, working frequency points and phase-locked loop circuit 40 are one-to-one relationship.Phase-locked loop circuit 40 as shown in Figure 2 may be disposed at operation core
Piece it is internal or external.Gap can be arranged according to actual needs between the frequency points of each working frequency points, frequency in the present invention, work
It is more more more the calculated performance of each kernel 50 can be given full play to make frequency point.Such as 6 working frequency points of setting, 500MHz, 550MHz,
600MHz, 650MHz, 700MHz, 750MHz.Therefore, it is more to be arranged that more phase-locked loop circuits 40 can be set in the present invention
Working frequency points, so that the calculated performance of each kernel 50 gives full play to.
It has to be noted that the frequency difference in the present invention between working frequency points needs to control in zone of reasonableness.Because working as kernel
50 improve a working frequency points, and the working frequency of the kernel will improve a frequency difference value, can be because of the raising of calculating speed
And then promote certain calculated performance.Simultaneously, the working frequency for promoting kernel may be because the reduction for calculating accuracy
And then certain calculated performance is lost.So frequency point setting module 10 should rationally control the frequency between adjacent working frequency points
Difference, when so that kernel 50 being transferred to a upper working frequency points from current working frequency, being benefited for the calculated performance of kernel 50 should be big
In loss.Preferably, the frequency difference between adjacent working frequency points is 1~10%.
Preferably, the step S403 can be raised by current working frequency of the phase-locked loop circuit 40 to kernel 50
Or it lowers.Specifically, if the current value of kernel 50 reaches scheduled calculating proper threshold value, by phase-locked loop circuit 40 by kernel
50 current working frequency is raised；Alternatively, passing through locking phase if the current value of kernel 50 reaches scheduled calculating error thresholds
Loop circuit 40 lowers the current working frequency of kernel 50.
The chip frequency modulation method that the present invention calculates equipment may also include that
If the kernel 50 for working at least one scheduled Optimization Work frequency point is more than scheduled first ratio, stop internal
Core 50 carries out frequency modulation.Or
If the number for working in the kernel 50 on an at least Optimization Work frequency point is most, stop carrying out frequency modulation to kernel 50.
For example, default one or more Optimization Work frequency points can be selected in several working frequency points, if most of kernels 50
Working frequency have arrived at the Optimization Work frequency point, show in operation chip that the working frequency of kernel 50 has been in optimization
State can give full play to the calculated performance of each kernel 50, it is no longer necessary to further frequency modulation, therefore stop 50 working frequency of kernel
Adjustment.Such as 6 working frequency points of setting, 500MHz, 550MHz, 600MHz, 650MHz, 700MHz, 750MHz, selection is wherein
Two Optimization Works frequency point 600Mhz and 650Mhz are Optimization Work frequency point, if being more than that 80% kernel 50 works in working frequency points
600Mhz and 650Mhz then stops carrying out frequency modulation to kernel 50.
Fig. 5 is the flow chart that the chip frequency modulation method of equipment is calculated in yet another embodiment of the invention, can pass through the core
Piece frequency modulation device 100 realizes that the calculating equipment includes at least one operation chip, and the operation chip is provided in multiple
Core.The method includes the steps have:
Multiple working frequency points are arranged to calculate the operation chip of equipment, by multiple kernels in operation chip in step S501
50 work in each working frequency points respectively.
Several different frequencies are arranged according to the frequency Regulation mechanism of operation chip level for each operation chip in this step
Point, and each kernel 50 of operation chip is allowed to work in each working frequency points.Such as 6 working frequency points of setting: 500MHz,
550MHz, 600MHz, 650MHz, 700MHz, 750MHz.Gap can root between the frequency points of working frequency points of the present invention, frequency
It is arranged according to actual needs, the working frequency points the more more can give full play to the calculated performance of each kernel 50.When starting frequency modulation switch
(not yet carrying out frequency modulation to kernel 50), kernel 50 can be averaged distribution, unequal distribution or random distribution according to pre-defined rule
It works in the working frequency points.It preferably, can be that operation chip is set by multiple phase-locked loop circuits 40 as shown in Figure 2
Set multiple working frequency points, naturally it is also possible to which multiple working frequency points are arranged for operation chip by other hardware or software.Preferably
It is that the frequency difference between adjacent working frequency points is 1~10%.
Step S502 presets the reference node point value of kernel 50, calculates correct weighted value, calculates error weight value, meter
It calculates proper threshold value and calculates error thresholds.The correct weighted value of calculating and calculating error weight value can be identical or not identical；
The calculating proper threshold value and calculating error thresholds can be identical or not identical.The reference node point value, calculate correct weighted value,
Error weight value is calculated, proper threshold value is calculated and calculates error thresholds and belongs to adjustable parameter, speed etc. can be adjusted according to frequency
Actual needs optimizes setting.
Preferably, it is arranged and adjusts the reference node point value of kernel 50 according to actual needs, calculates correct weighted value, calculating
Error weight value, calculate proper threshold value and/or calculate error thresholds, calculate correct weighted value and calculating error weight value it is identical or
Person is not identical, calculates proper threshold value and calculating error thresholds are identical or not identical.
Correct weighted value is calculated by control and calculates the resident of the expectation tolerance of Ratio control kernel 50 of error weight value
Error rate.The calculation formula of the resident error rate are as follows: the resident correct weighted value of error rate=calculating/(calculate correct weighted value+
Calculate error weight value).
Correct weighted value is calculated by control and calculates the order of magnitude control adjustment period of error weight value.
Proper threshold value is calculated by control and calculates the order of magnitude control adjustment period of error thresholds.
Whether step S503, analysis kernel 50 are correct in each calculating of current working frequency.
Kernel 50 can carry out a variety of different calculating, can analyze kernel 50 it is each certain or it is several calculating whether just
Really.Whether the preferably analysis calculated Nonce of kernel 50 is correct.
Step S504, kernel 50 are often computed correctly at least once, increase on reference node point value and once calculate correct weight
Value, and the every erroneous calculations of kernel 50 are at least once, and primary calculating error weight value is reduced on reference node point value.Preferably
It is that kernel 50 is often computed correctly once, increases on reference node point value and once calculate correct weighted value.It is of course also possible to be arranged
It is often computed correctly n times (N is the natural number greater than 1) for kernel 50, increases on reference node point value and once calculates correct weighted value.
The every erroneous calculations of kernel 50 are primary, and primary calculating error weight value is reduced on reference node point value.Of course, it is possible to be set as kernel
50 every erroneous calculations n times (N is the natural number greater than 1), reduce primary calculating error weight value on reference node point value.
Step S505 judges whether the current reference nodal value of kernel 50 reaches and calculates proper threshold value or the wrong threshold of calculating
Value.If the current reference nodal value of kernel 50 reaches calculating proper threshold value, S506 is thened follow the steps, if the current reference of kernel 50
Nodal value reaches calculating error thresholds, thens follow the steps S507.
This step preferably includes:
(1) according to preset real-time adjustment instruction, whether the current reference node of real-time judge kernel 50 is reaching calculating just
True threshold value calculates error thresholds；Or
(2) it is instructed according to preset timing adjustment, in the adjustment time section of timing adjustment instruction setting, judges kernel 50
Current reference node whether reach calculate proper threshold value or calculate error thresholds；Or
(3) whether instant adjustment instruction, the current reference node of analysis kernel 50 reach the correct threshold of calculating based on the received
Value calculates error thresholds.
Step S506 shows that the kernel 50 not yet reaches if the current reference nodal value of kernel 50 reaches calculating proper threshold value
To optimal computed performance, the current working frequency of kernel 50 is raised.Preferably, if the current value of kernel 50 reaches meter
Proper threshold value is calculated, a upper working frequency points will be transferred in the current working frequency of kernel 50.
This step preferably includes:
(1) according to preset real-time adjustment instruction, if the current reference node of kernel 50 reaches calculating proper threshold value, in real time
The current working frequency of kernel 50 is raised；Or
(2) it is instructed according to preset timing adjustment, in adjustment time section, if the current reference node of kernel 50 reaches meter
Proper threshold value is calculated, the current working frequency of kernel 50 is raised；Or
(3) instant adjustment instruction will be interior if the current reference node of kernel 50 reaches calculating proper threshold value based on the received
The current working frequency of core 50 is raised.And stops adjustment instruction based on the received, stop the work at present to kernel 50
The adjustment of frequency point.
Step S507 shows the calculating of the kernel 50 if the current reference nodal value of kernel 50 reaches calculating error thresholds
Performance is not enough to work in current working frequency, and the current working frequency of kernel 50 is lowered.Preferably, if kernel
50 current value reaches calculating error thresholds, and the current working frequency of kernel 50 is lowered to next working frequency points.
This step preferably includes:
(1) according to preset real-time adjustment instruction, if the current reference node of kernel 50 reaches calculating error thresholds, in real time
The current working frequency of kernel 50 is lowered；Or
(2) it is instructed according to preset timing adjustment, in adjustment time section, if the current reference node of kernel 50 reaches meter
Error thresholds are calculated, the current working frequency of kernel 50 is lowered；Or
(3) instant adjustment instruction will be interior if the current reference node of kernel 50 reaches calculating error thresholds based on the received
The current working frequency of core 50 is lowered；Stop adjustment instruction based on the received, stops the current working frequency to kernel 50
Adjustment.
For example, user can send instant adjustment instruction, the every meter of user setting kernel 50 to calculating equipment at any time as needed
It is primary to calculate correct Nonce, increases weight A on reference mode, the every calculating mistake Nonce of kernel 50 is primary, in the reference mode
Upper reduction weight B.It is when current increase numerical value reaches calculating correct number threshold value C, the upward working frequency points of kernel 50 are advanced.When
Preceding reduction numerical value reaches when calculating error number threshold value D, by kernel 50 to next working frequency points depression of order.In addition, user can basis
It needs after calculating equipment receives the stopping adjustment instruction, to stop immediately internal to equipment transmission stopping adjustment instruction being calculated at any time
The frequency modulation of core 50.
It will be appreciated by persons skilled in the art that a upper working frequency points are not limited in upper operated adjacent frequency point,
More than one upper operated adjacent frequency point be may also set up as a upper working frequency points；Next working frequency points are not limited in
Next operated adjacent frequency point may also set up more than one next operated adjacent frequency point as next working frequency points.Preferably
It is that the frequency difference between current working frequency and a upper working frequency points is 1~10% and current working frequency and next work
The frequency difference for making frequency point is 1~10%, so that kernel 50 is transferred to a upper working frequency points or next work from current working frequency
When making frequency point, the benefited of the calculated performance of kernel 50 should be greater than losing.It as, will be on the current working frequency 600MHz of kernel 50
It is transferred to a working frequency points 700MHz；The current working frequency 600MHz of kernel 50 is lowered to next working frequency points
500MHz.And so on, herein not to a upper working frequency points, the spacing of subsequent work frequency point is limited.
This step preferably can carry out frequency modulation to kernel 50 by phase-locked loop circuit 40 or software as shown in Figure 2.That is basis
Kernel 50 is adjusted to the frequency that suitably works for according to the practical calculated performance of kernel 50 by the frequency Regulation mechanism of kernel level
Point, the frequency of the high kernel 50 of up-regulation calculated performance, lowers the frequency of the low kernel 50 of calculated performance, to give full play to each
The calculated performance of kernel 50.
For example, setting 400000 is used as reference node point value, calculates correct weighted value and be set as 180, calculates error weight value and set
It is 9000, calculates proper threshold value and calculating error thresholds are set as 100000.
Kernel 50 is often computed correctly at least once, and 180 (calculating correct weighted value) are added on the reference node point value；Kernel 50
Every erroneous calculations at least once, reduce by 9000 (calculating error weight value) on the reference node point value；With the reference node point value
On the basis of, often increase or decrease 100000 (calculate proper threshold value and calculate error thresholds), a upward frequency point is advanced or to next
Frequency point depression of order.
Present scheme is similar to mistake and correct tug-of-war mechanism, and correct and mistake can have different weights.If
Reference node point value is set, a correct result is often received, increase once calculates correct weighted value, often receives an error result, subtract
Few primary calculating error weight value carries out the up-regulation or downward of frequency if reward or punishment are more than respective side thresholding.It can be with
Understanding that adjustment system has a marker, reference node point value is the initial value of maker, if there is correctly submitting then maker+180,
Mistake submits then maker -9000 every time.Correct (N is the natural number more than or equal to 1) by n times, (M is big after M mistake
In or equal to 1 natural number), marker should be in the position of 400000+N*180-M*9000, if Marker be more than certain side
Thresholding then carries out corresponding frequencies adjustment (up-regulation or downward).Then every secondary frequencies are adjusted to all initialize the value on new frequency point,
Current reference nodal value is re-set as to initial reference node point value.
Fig. 6 is the flow chart that the preferred chip frequency modulation method of equipment is calculated in yet another embodiment of the invention, can pass through institute
The realization of chip frequency modulation device 100 is stated, the calculating equipment includes at least one operation chip, and the operation chip is provided with multiple
Kernel.The method includes the steps have:
Multiple working frequency points are arranged to calculate the operation chip of equipment, by multiple kernels in operation chip in step S601
50 work in each working frequency points respectively.
Step S602 presets the reference node point value of kernel 50, calculates correct weighted value, calculates error weight value, meter
It calculates proper threshold value and calculates error thresholds.
Whether step S603, the Nonce that analysis kernel 50 is submitted every time are correct.
Preferably, this step further comprises:
(1) after kernel 50 submits a Nonce, Nonce is calculated first as a result, by scheduled algorithm by kernel 50
It include fisrt feature in one result.
(2) Nonce is calculated second as a result, wrapping in the second result by identical algorithm by the checking computations unit of operation chip
Contain second feature.
(3) it if fisrt feature is identical as second feature, checks unit and determines that Nonce is correct Nonce, otherwise determine
Nonce is wrong Nonce.
For example, kernel 50 is submitted after calculating a Nonce, the first Kazakhstan is calculated in Nonce insertion block head
It wishes as a result, preceding 20 values of the first Hash result are 0 (fisrt feature).It checks unit 212 and the Nonce is also embedded in block head
The second Hash result is calculated, if first 20 of the second Hash result are also 0 (second feature), then it is assumed that the Nonce is
Primary correct submission.
Step S604, kernel 50 is every to submit correct Nonce at least once, increases primary calculate correctly on reference node point value
Weighted value, kernel 50 is every to submit mistake Nonce at least once, and primary calculating error weight value is reduced on reference node point value.It is excellent
Choosing increases on reference node point value in the primary correct Nonce of every submission of kernel 50 and once calculates correct weighted value.Certainly,
It may be set to be the every submission N of kernel 50 (N is greater than 1 natural number) secondary correct Nonce, increase on reference node point value primary
Calculate correct weighted value.Kernel 50 is every to submit primary mistake Nonce, and primary calculating error weight is reduced on reference node point value
Value.It is of course also possible to the every submission N of kernel 50 (N is greater than 1 natural number) secondary mistake Nonce is set as, on reference node point value
Reduce primary calculating error weight value.
Step S605 judges whether the current reference nodal value of kernel 50 reaches and calculates proper threshold value or the wrong threshold of calculating
Value.If the current reference nodal value of kernel 50 reaches calculating proper threshold value, S606 is thened follow the steps, if the current reference of kernel 50
Nodal value reaches calculating error thresholds, thens follow the steps S607.
Step S606, if the current reference nodal value of kernel 50 reaches calculating proper threshold value, by the work at present of kernel 50
A working frequency points are transferred on frequency point.
Step S607, if the current reference nodal value of kernel 50 reaches calculating error thresholds, by the work at present of kernel 50
Frequency point is lowered to next working frequency points.
In a concrete application embodiment of the invention: 6 phase-locked loop circuits 40 are used, 6 working frequency points are set:
500MHz, 550MHz, 600MHz, 650MHz, 700MHz, 750MHz.Such as and it is arranged 400000 as reference node point value, calculates just
True weighted value is set as 180, calculates error weight value and is set as 9000, calculates proper threshold value and calculating error thresholds are set as

It is as follows that the number of cores being distributed in each respective frequencies that power plate counts is calculated according to 4 pieces:
Calculate power plate 0:[294 26 96 224 1,023 1665]
Calculate power plate 1:[274 47 111 212 963 1721]
Calculate power plate 2:[350 25 153 369 1,381 1050]
Calculate power plate 3:[488 33 184 367 1,342 950]
Firstly, combined data further illustrates mechanism.Correct weighted value/(calculate correct is calculated according to resident error rate S=
Weighted value+calculating error weight value), and by given data can extrapolate the resident error rate S of kernel 50 (being interpreted as can
Some frequency point is resided in for a long time) it is 180/ (180+9000)=1.29%, the permanent work of kernel 50 at this time is on some frequency point
(because expectation step-length is 0 at this time), working frequency will not be raised or be lowered.It can be deduced that if the calculating error rate of kernel 50 is big
In 1.29% (resident error rate S), working frequency will be raised；If the calculating error rate of kernel 50 is (resident less than 1.29%
Error rate S), working frequency will be lowered.
According to the difficulty being arranged, (difficulty is related with benchmark is examined, and calculates accuracy to kernel 50 and has an impact, degree-of-difficulty factor
Bigger, accuracy is lower；It is on the contrary then accuracy is higher), it can calculate the approximate period for making mistake and adjusting when rising, it is assumed that mistake
Rate is e, then the expectation step-length of each Nonce are as follows:
(1-e) * 180-e*9000=180-9180e.By taking e=0.5% as an example, it is expected that step-length=134.1；It is with e=1%
Example, it is expected that step-length=88.2；By taking e=2% as an example, it is expected that step-length=- 3.6.
By taking 650MHz as an example, kernel 50 submits 1.3/second that are desired for of single Nonce (to submit 1.3 within i.e. 1 second
Nonce).It is explained with the scene that e is 0.5%, i.e., after 746 Nonce submission processes, so that it may it is expected that adjusting upward
Once；E is 1.0% needs, 1134 submissions, it is contemplated that adjusts upward once, if error probability is 2.0%, needs 27778
