To combine the accompanying drawing in the embodiment of the invention below, the technical scheme in the embodiment of the invention is carried out clear, intactly description, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the present invention's protection.
The embodiment of the invention provides a kind of multi-system data processing unit, and is as shown in Figure 4, and said multi-system data processing unit comprises: channel polling table 41, counter 42, channel to channel adapter 43 and data selector 44.
Channel polling table 41 is used to store the channel number according to the pre-defined rule ordering; Each channel number all need be stored in the channel polling table 41 according to certain cycle in general; For example the channel number of first address storage is 5; And its cycle is 4, and the channel number of memory address storages such as the 6th, 10 is 5 so; If the channel number of second memory address storage is 1, and the cycle be 8, the channel number of memory address storages such as the 9th, 17 is 1 so.
For the channel number in can read-out channel polling list polling table 41, the embodiment of the invention can be counted through counter 42, selects the channel number stored in the appropriate address successively according to count value by channel to channel adapter 43 then.Particularly, counter 42 is used for clock is counted, and when count value reaches the mould value of counter, again clock is counted, and mould value that can counter in the present embodiment is set to the memory address number of channel number in the channel polling table; And channel to channel adapter 43 is used for successively number being specially from said channel polling table selector channel: channel to channel adapter 43 is used for selecting the channel number the count value corresponding stored address with counter from said channel polling table; For example: if the count value of counter is 10; Then from the 10th address, read corresponding channel number, can find out specifically that from present embodiment the channel number of from the 10th address, reading is 5.Said data selector 44 is used to connect the data channel of at least two kinds of standards, and after obtaining said channel number, said data selector 44 is used for the data of selected channel number corresponding data passage are outputed to the resource pool of data processing.
Through counter timeslice is divided in the embodiment of the invention, the mould value of counter is big more, and the maximum polling cycle that is equivalent to the channel polling table is also big more.Result through counter output can directly find channel number in its corresponding address, so that data selector breaks into serial flow according to the channel number dateout that obtains and with parallel data.And the channel data of different systems can output to same resource pool through data selector in embodiments of the present invention, has practiced thrift the number of resource pool.
Above-mentioned Fig. 4 is the scheme that adopts a counter to realize; The embodiment of the invention can also adopt plural counter to realize the selection of channel number; Specifically as shown in Figure 5, embodiment of the invention multi-system data processing unit comprises: the above counter of channel polling table 51, two 52, channel to channel adapter 53 and data selector 54.The data channel setting of the corresponding every kind of standard of the number of concrete counter; And the mould value of each counter is identical with the cycle of data channel in the channel polling table of its corresponding standard, is respectively equipped with the data channel identical delayed clock of original position in the channel polling table with its corresponding standard.Identical among the function of channel polling table 51 and data selector 54 and Fig. 4, and each counter is counted and when count value reaches the mould value of counter, again clock is counted clock behind the delayed clock that postpones setting; Said channel to channel adapter 53 is used for successively from said channel polling table selector channel number being specially: channel to channel adapter 53 is used for when counter begins clock carried out at every turn, reading the channel number next memory address from said channel polling table.
Said channel polling table need be by the pre-defined rule channel number that sorts, and there is following configuration difficult point in the pre-defined rule here:
At the particular location that distributes each channel number is possibly exist because original position and cycle inconsistent causes a certain memory address need distribute to two channel numbers, causes conflict.For example: the polling interval of passage 0 is n1; The polling interval of passage 1 is n2; Between two passages for the first time the polling interval be l; If then x cycle configuration of passage 0 need be satisfied following formula: x*n1=y*n2+l with y cycle configuration of passage 1, and when (y*n2+l)/n1 is integer, will occur conflict between passage 0 and the passage 1.For example: n1=5, n2=7, y=3, l=4 configuration conflict can occur during x=5.
For fear of above-mentioned conflict, as shown in Figure 6, the embodiment of the invention adopts following method to make above-mentioned channel polling table:
601, clock frequency is obtained the poll precision of channel polling table divided by the maximum polling cycle of channel polling table; Clock frequency is 122.88MHz in the present embodiment, if comprise L memory address of preserving passage in the channel polling table, then the maximum polling cycle of channel polling table is L, and the poll precision of corresponding channel polling table is: s=122.88MHz/L.
Maximum polling cycle with the channel polling table is decided to be 64 in the present embodiment, and then corresponding poll precision is 1.92MHz, and its corresponding sample rate is 1.92MSPS.
602, the signal rate with each standard data is converted into poll over-sampling speed, 2 of the poll precision that said poll over-sampling speed is the channel polling table
NDoubly, N is a natural number;
With the poll precision is that 1.92MHz is an example, and the signal rate of each standard data transforms a kind of that the poll over-sampling speed that obtains should be in the following data: 1.92MSPS, 3.84MSPS, 7.68MSPS, 15.36MSPS, 30.72MSPS, 61.44MSPS, 122.88MSPS etc.The corresponding polling cycle of above-mentioned poll over-sampling speed is followed successively by: 64,32,16,8,4,2,1.
Because after the signal rate of each standard data is converted into poll over-sampling speed; Actual employing speed is possibly greater than signal rate; There is certain bandwidth waste; In order to make bandwidth waste less as far as possible, the embodiment of the invention can the poll over-sampling speed that each standard data are corresponding be taken as data that just are not less than signal rate, and does not get other bigger numerical value; For example: the poll over-sampling speed for 6.5MSPS is corresponding should be got 7.68MSPS, and does not get other speed greater than 7.68MSPS.
Mixing mould applied clock frequency is 122.88MHz, need to support that 8 kinds of standards coexist simultaneously, and eight kinds of standards is followed successively by: GSM, LTE15M, CDMA, LTE1.4M, LTE5M, LTE20M, UMTS, LTE10M; Corresponding signal rate and the poll over-sampling speed of various standards specifically sees the following form:
| Channel number | The carrier wave standard | Signal rate | Poll over-sampling |
| 0 | GSM | 6.5MSPS | 7.68MSPS |
| 1 | LTE15M | 23.04MSPS | 30.72MSPS |
| 2 | CDMA | 1.2288MSPS | 1.92MSPS |
| 3 | LTE1.4M | 1.92MSPS | 1.92MSPS |
| 4 | LTE5M | 7.68MSPS | 7.68MSPS |
| 5 | LTE20M | 30.72MSPS | 30.72MSPS |
| 6 | UMTS | 3.84MSPS | 3.84MSPS |
| 7 | LTE10M | 15.36MSPS | 15.36MSPS |
603, dispose the memory location of each standard data respective channel number in the channel polling table from big to small according to poll over-sampling speed, the size order if poll over-sampling speed is identical according to channel number is configured; In the present embodiment each standard data respective channel memory cycle number in the channel polling table be poll over-sampling speed divided by the poll precision, specifically see the polling cycle that 602 exemplified draw.
The channel polling table configuration of above-mentioned for example middle GSM, LTE15M, CDMA, LTE1.4M, LTE5M, LTE20M, UMTS, LTE10M needs; Earlier with polling cycle 4 configuration LTE15M and LTE20M; Then with polling cycle 8 configuration LTE10M; Then with polling cycle 16 configuration GSM and LTE5M, again with polling cycle 32 configuration UMTS, at last with polling cycle 64 configuration CDMA and LTE1.4M; The channel polling table that specifically obtains is as shown in Figure 7.
After the automatic tabulation scheme of the channel polling table that the employing embodiment of the invention provides, because the channel number of every kind of standard is all with 2
NBe polling cycle, and maximum polling cycle also is 2 Nth power (get 64 in the present embodiment, specifically can change other data into); And (y*n2+l)/n1=y*n2/n1+1/n1; Wherein y*n2/n1 is an integer, and 1/n1 can be integer scarcely, so (y*n2+l)/n1 can not be integer certainly; So; Just there is not the collision problem in the channel polling table, not only simplified the process of automatic tabulation, realized the automation of automatic tabulation yet.
And, adopting after the embodiment of the invention, the configuration space of every kind of standard has satisfied from the beginning to the end that order all is not more than clock frequency divided by data rate, and also will satisfy this interval from tail to the end the time and all be not more than clock frequency divided by data rate.If regarding the polling sequence cycle as a circumference, the configuration cycle of each standard is actually just that circumference has carried out 2 in the present embodiment
NFive equilibrium has been guaranteed from the beginning to the end and to the end regular in full accord of tail like this.
Because communication system has strict requirement (using such as MIMO) to the certainty of delay process; But the combination of the scene in the scheme that the embodiment of the invention provides is often more; The poll over-sampling frequency that data adopted of various different systems is also incomplete same; Make that the time-delay of various scenes can not normalization, cause mixing that the time-delay configuration of modular system is very complicated safeguards with being difficult to.In order to make that the time-delay of various scenes in the embodiment of the invention can normalization; The embodiment of the invention externally provides overall timing signal; And above-mentioned counter is connected on the overall timing signal, said counter is counted clock when receiving overall timing signal again.The cycle of overall timing signal can be the least common multiple of each standard cycle data in general, upgrades simultaneously when overall timing signal arrives so that guarantee the data of all standards, makes all standard data when overall timing signal arrives, align once.
Behind the overall timing signal that the employing embodiment of the invention provides, can be so that the time-delay of the overall relatively timing signal of the data of each standard to be just fixing, the edge communications system handles time-delay.And to the serial flow parallelization, the time-delay characteristics of channel polling and standard, passage and configuration are irrelevant fully like this according to the maximum delay of data flow parallelization (depending on that the polling cycle table is long) for the recipient.
The embodiment of the invention can be connected to data selector the data channel of various standards through buffer memory when realizing; The data channel corresponding cache of every kind of standard is used for when the data of corresponding data passage arrive, flag register being changed to the data effective status, the data that simultaneously can also buffer memory receive; Data selector is behind the channel number that receives channel to channel adapter output; If flag register is the data effective status in this passage corresponding cache; Then data selector just reads corresponding data; And output to resource pool, be buffered in simultaneously after data selector reads the data of said data channel flag register is changed to the data disarmed state; When if flag register is the data disarmed state, then skip epicycle and read, wait for when next channel number arrives in reading of data.
Because every kind of all certain data rate of poll over-sampling speed that the standard data are corresponding in the embodiment of the invention more than or equal to itself; So; Each standard data has all adopted the scheme of over-sampling; Below with a kind of data instance of standard wherein, the core concept of over-sampling scheme among the present invention is described in detail:
Base band data for LTE20M; Whenever at a distance from data of 8 clocks arrivals, as shown in Figure 8 according to figure, stain is represented the data that LTE20M arrives in order successively among the figure under the 245.76MHz clock; And poll over-sampling speed is greater than the base-band data signal data of LTE20M; Its sketch map is seen the frame of broken lines among Fig. 8, and each frame of broken lines is all represented a poll over-sampling cycle, and the arrow among Fig. 8 is represented to carry out data sampling according to poll over-sampling speed.
In the embodiment of the invention, when base band data arrives, with the flag register set in inside; When the poll over-sampling speed of setting in according to the channel polling table is polled to this passage, if this flag register is " 1 ", then think the data effective status, then data selector reads the data in this passage, and flag register simultaneously clear " 0 "; When the poll over-sampling speed of setting in according to the channel polling table is polled to this passage, if this flag register is " 0 ", then think the data disarmed state, data selector is reading of data not just, is equivalent to a gap.Certainly, if this flag register is " 0 ", arriving simultaneously when base band data and over-sampling poll is to handle according to the data effective status.
Adopted after the above-mentioned gap processing mode; Can find out; Some sampled point in the poll over-sampling speed is not need reading of data, and is as shown in Figure 8, and dotted line and hollow arrow are exactly the sampled point that does not need reading of data among the figure; Because base band data does not also arrive when poll over-sampling speed arrives this sampled point, do not need reading of data.And, because poll over-sampling speed is more than or equal to data rate, so the situation of loss of data can not occur.
Certainly, the poll over-sampling speed that is adopted for data and its of different systems is different, and gap point that obtains at last and sampling time point and data arrives time point are difference to some extent, specifically can expand with reference to Fig. 8, repeat no more here.
A kind of application scenarios of the embodiment of the invention is described below; A kind of comparatively general structure is FIR (Finite Impulse Response in the intermediate frequency chip; The response of limit for length's unit impulse is arranged) filter; The characteristics of FIR filter are cache resources and take advantage of the demand that adds resource all higher, and the filter demand that suppresses especially for spectral shaping and nearly band is than higher.Under the scene for the multi-system data passage, the scheme that can adopt the embodiment of the invention to provide makes a plurality of data channel can share a FIR filter, go forward side by side row cache and multiply-add operation.Specifically as shown in Figure 9; The data channel of each standard is connected to the embodiment of the invention through the tap buffer memory multi-system data processing unit is provided; Become serial data stream to output to the FIR filter transformation of data by the multi-system data processing unit, filtering operation such as add with taking advantage of so that the FIR filter carries out corresponding buffer memory.The description of Fig. 4 to Fig. 8 is specifically seen in the realization of multi-system data processing unit in the present embodiment.
And when mixing mould and using, the filtering exponent number of different systems semaphore request maybe be different, and the filtering exponent number that needs also has difference on parity, and this not only requires to mix mode filter and will design according to top step number, and also requirement can support real-time change exponent number to handle.
Adopted tap buffer memory shown in figure 10 in the embodiment of the invention, MUX1 among the figure (MUX, multiplexer) and MUX4 are used to realize the switching on 128 rank and 96 rank, and MUX2 and MUX3 are used to realize the switching on odd even rank.
The embodiment of the invention not only can be used in the more scene of FIR filter to reduce the use amount of FIR filter, also can be used in the scene of other resource pools, reduces the use amount of resource pool.For example, more for a long time, the intermediate frequency chip need dock the multi-disc baseband chip simultaneously at the interface of intermediate frequency chip, if adopt prior art to carry out Interface design, can cause the logical design of interface butted part complicated, and the interface of use is more; And more chip pin all can have bigger influence to back end design, Chip Packaging, package area, chip cost etc.
Also can directly be interpreted as resource pool for the interface in the intermediate frequency chip; Between the data of multi-modulation scheme and interface, connect the multi-system data processing unit that the embodiment of the invention provides; Through this device the mode of the The data poll of multi-modulation scheme is outputed to an interface, realized the multiplexing of interface.Concrete multi-system data processing unit is realized can be with reference to the specific descriptions of Fig. 4 to Fig. 8.
After adopting the embodiment of the invention to carry out Interface design, can improve the utilance of interface, reduce the quantity of pin in the interface in theory as far as possible, make Interface design more simple.And help the normalization of multimode wireless communication platform, dock different baseband chips and only need revise the corresponding interface logic of interface FPGA and get final product, mixed mould intermediate frequency chip is general fully.
The embodiment of the invention also provides a kind of multi-system type data processing method, needs in this method at least two kinds of corresponding channel numbers of standard data channel are sorted according to pre-defined rule, and concrete sequencer procedure is seen the description among Fig. 6, repeats no more here.After the ordering that obtains channel number, the embodiment of the invention need be according to sort successively selector channel number of pre-defined rule, so that the data of output respective channel number are to resource pool, shown in figure 11, its concrete implementation method comprises:
111, at first clock is counted, and count value is exported;
Counting in the embodiment of the invention need be counted clock when count value reaches the mould value of counter again, perhaps when receiving overall timing signal, again clock is counted.In general, the cycle of the overall timing signal in the present embodiment is the least common multiple of each standard cycle data.
112, after obtaining count value; Directly select with count value corresponding stored address in channel number; For example; Count value is 30, obtains the channel number of its storage in then direct 30 memory addresss of Cheng Congdi, is to be determined by the collocation method described in Fig. 6 and stored which channel number inside concrete.
113, when clock is counted; The embodiment of the invention also need receive the data in the data channel; And when the data of data channel arrive, flag register is changed to the data effective status, and flag register should be in the data disarmed state when not receiving data.
114, behind the channel number that obtains taking out, judge whether the flag register of this channel number corresponding data passage is the data effective status, if be the data effective status, then carry out 115; If be the data disarmed state, then carry out 116.
115, directly read corresponding data in this channel number corresponding data passage, and output to the resource pool of data processing, then flag register is changed to the data disarmed state, return and carry out 111.
116, skip data and read, return and carry out 111.
The embodiment of the invention also provides another kind of multi-system type data processing method, needs in this method at least two kinds of corresponding channel numbers of standard data channel are sorted according to pre-defined rule, and concrete sequencer procedure is seen the description among Fig. 6, repeats no more here.After obtaining the good ordering of passage, the embodiment of the invention need be according to sort successively selector channel number of pre-defined rule, so that the data of output respective channel number are to resource pool, shown in figure 12, its concrete implementation method comprises:
121, clock is counted behind the delayed clock that postpones setting to the data channel of every kind of standard, and when count value reaches the mould value of counter, again clock is counted.
The mould value of each counter is identical with the cycle of data channel in the channel polling table of its corresponding standard in the present embodiment, and delayed clock is identical with data channel original position in the channel polling table of its corresponding standard.
122,, reads by each counter the channel number in next memory address when beginning at every turn or restart clock carried out.
123, when clock is counted; The embodiment of the invention also need receive the data in the data channel; And when the data of data channel arrive, flag register is changed to the data effective status, and flag register should be in the data disarmed state when not receiving data.
124, behind the channel number that obtains taking out, judge whether the flag register of this channel number corresponding data passage is the data effective status, if be the data effective status, then carry out 125; If be the data disarmed state, then carry out 126.
125, directly read corresponding data in this channel number corresponding data passage, and output to the resource pool of data processing, then flag register is changed to the data disarmed state, return and carry out 121.
126, skip data and read, return and carry out 121.
