The complexity of the interaction flow of mouth processing platform processing message, improves DSP disposal abilities, and then cause the interface processing platform
It is also equipped with compatible, portability.
The embodiment of the present invention is described in further detail with reference to Figure of description.
The method of MAC layer and PHY layer interacting message includes the descending of message and issues handling process and the up of message is reported
Handling process.
Wherein, as shown in figure 1, the exchange method of the message of the embodiment of the present invention one is the descending handling process issued, including：
Step 100, the DSP core in upper level in interface processing platform reads the shared drive that itself shares with upper strata
In message package, and the message package read is stored in the local memory of the DSP core in upper level；
Step 101, the DSP core in upper level is parsed to the attribute information of every message in message package, and according to
Attribute information determines that the message in processing message package is needed after next stage processing, it is determined that needing to handle the MAC-PHY interfaces of message
The DSP core of next stage is in technology platform；
Step 102, the DSP core in upper level stores message to itself with being in next stage in the form of message package
In the shared shared drive of DSP core.
It should be noted that the interface processing platform in the present invention is MAC-PHY interface processing platforms.
In step 100, the DSP core in upper level in interface processing platform read itself share with upper strata it is shared in
If the message that the DSP core in upper level in the message package deposited is received comes from MAC layer, upper strata refers to MAC layer, if place
When the message received in the DSP core of upper level comes from other DSP cores, then upper strata refers to DSP core.
Wherein, the descending handling process that issues of message is carried out in preset time, that is to say, that when one default
In, complete the descending of message and issue flow, such as：One preset time is the time of a frame, i.e. 4.615ms, a frame bag
Containing eight time slots.
The exchange method of the message of the embodiment of the present invention one is illustrated with reference to Fig. 2, if in DSP in upper level
DSP core is DSP core 0, it is assumed that preset time is the time of a frame, and one of frame is divided into several frame slots.
Wherein, the number of every layer of DSP core can be configured as needed.
If it is preferred that the upper strata in upper level DSP core is MAC layer, the DSP core in upper level only has one
It is individual.
Interacted that is, only one of which DSP core is DSP core 0 with MAC layer by the progress of shared drive 0 message package
Storage, so reduces the interactive interface with other DSP cores.
MAC layer can be to physical layer issuing message bag to shared drive 0, by disappearing in shared drive 0 every the time of a frame
Breath interaction mark set, and trigger signal is sent to DSP core 0, to notify DSP core 0 to go to handle MAC layer message package.
Wherein, the interacting message mark of shared drive can be that shake hands position or other flags are used to represent in shared drive
With the presence or absence of message.Under normal circumstances, when the interacting message of shared drive is designated 1, represent there is message package in shared drive；
When the interacting message of shared drive is designated 0, represent shared drive in do not deposit message package, can also shared drive message
When interaction is designated 0, represent there is message package in shared drive；When the interacting message of shared drive is designated 1, represent in shared
Message package is not deposited in depositing, wherein, interaction mark is manually set.
Trigger signal can be used to notify DSP core or ARM cores to go processing shared for the signal of internuclear interruption or other forms
Message package in internal memory.
It is preferred that the DSP core in upper level read message package in the shared drive itself shared with upper strata it
Before, in addition to：
The DSP core in upper level is received from upper strata transmission for notifying the DSP for being in upper level
Core read itself share with upper strata it is shared in message package trigger signal.
That is, DSP core 0 are before the message package in reading shared drive 0, what receiving mac layer was sent is used to lead to
Know that DSP core 0 read the trigger signal of message package in shared drive 0, so that DSP core 0 can be preferentially read in shared
The message package in 0 is deposited, and it is handled.
DSP core 0 are after the trigger signal of MAC layer transmission is received, to being carried out in shared drive 0 with the presence or absence of message package
Judge, if without message package in shared drive 0, DSP core 0 are no longer handled it, it is to avoid do not deposited in shared drive
In the case of putting message package, MAC layer sends trigger signal to DSP core 0, and DSP core 0 directly read the situation of message package
Occur, to ensure being normally carried out for subsequent step.
To judging in shared drive 0 with the presence or absence of message package, it is preferred that including two schemes：
First, DSP core 0 determine that the interacting message mark for the shared drive 0 shared with MAC layer represents to be total to MAC layer
There is message package in the shared drive enjoyed.
Wherein, the interacting message mark of the shared drive 0 shared with MAC layer is to arrive message package storage in MAC layer
Set after in the shared drive 0 shared with MAC layer.
Second, the message statistics number for the shared drive 0 that DSP core 0 share with MAC layer is not 0.
Then, DSP core 0 read the message package in shared drive 0, and the message package is stored in into DSP core's 0
In local memory.
It is preferred that after the message package to be stored in DSP core 0 DSP core 0 local memory, by shared drive
In interacting message mark set to 0, illustrate message in shared drive to be empty, to ensure being normally carried out for subsequent step.
DSP core 0 are parsed according to the attribute information of message in message package to the message being issued in local memory,
And the DSP core that the attribute information according to message is handled the message parsed with the mapping relations determination of corresponding DSP core,
The attribute information of message is to configure good in systems with the mapping relations of corresponding DSP core.
Wherein, the attribute information of the message includes but is not limited to the parameters such as type of message, carrier wave ID, channel type.
Illustrate how the message in local memory determines so that DSP core 0 are parsed according to carrier wave ID as an example below
The DSP core handled the message parsed.DSP core 0 are parsed to the carrier wave ID of message, according to being pre-configured with
Carrier wave ID and DSP core between corresponding relation, so that it is determined that carrying out processing DSP core to the message that parses.Normal conditions
Under, the corresponding DSP core of message that carrier wave ID is 0 or 1 is DSP core 0, therefore carrier wave ID is stayed in into DSP for 0 or 1 message
Core 0 is handled.If the corresponding DSP core of message that carrier wave ID is 2 or 3 is DSP core 1, by the message parsed
Carrier wave ID for 2 or 3 message to be issued in the form of message package in shared drive 1, other carrier waves ID message and above-mentioned side
Method is similar, will not be repeated here.
When the method that is handled according to type of message, channel type or other attribute informations the message parsed with
It is similar according to the method that carrier wave ID is handled the message parsed, it will not be repeated here.
DSP core 0 determine the DSP core to tackling its processing according to the message of parsing, are sent to corresponding with corresponding DSP
During the shared shared drive of core is internuclear shared drive.Specifically, the message that DSP core 0 are parsed according to carrier wave ID
The message that DSP core 1 in need, DSP core 3 or other DSP cores are handled, is handled without DSP core 2
Message, then DSP core 0 message package of corresponding message is issued to successively in different frame slots and is total to corresponding DSP core
In the shared drive enjoyed.
Corresponding message package is issued to what is shared with corresponding DSP core successively in different frame slots in DSP core 0
After in shared drive, how to trigger the DSP core of next stage has kinds of schemes to the progress processing in its corresponding shared drive, under
Three kinds of schemes are enumerated in face：
First, DSP core 0 send trigger signal successively to the DSP core of corresponding processing message in need, notify under it
The corresponding DSP core of one-level goes corresponding shared drive to read corresponding message package, then can trigger the DSP core of next stage to its correspondence
Shared drive in message package be read out, otherwise without trigger action；
Second, the corresponding interacting message with the shared drive of DSP core 0 of other DSP cores (in addition to DSP core 0) detection is identified, and
Interacting message mark represents and there is message package in the shared drive of DSP core 0, then can trigger the DSP core corresponding shared to its
Message package in internal memory is read out, otherwise without trigger action；
Third, other DSP cores (in addition to DSP core 0) detect that the corresponding message statistics number with the shared drive of DSP core 0 is not
Zero, then it can trigger the DSP core and the message package in its corresponding shared drive is read out, otherwise without trigger action.
As DSP core 1 according to above-mentioned a certain method judge shared drive 1 i.e. DSP core 1 and DSP between DSP core
There is message package in Core0 shared drive, then read the message between DSP core in shared drive 1 in the frame slot set, and will
Message identifier between DSP core in shared drive 1 is set to 0, and in the frame slot set, DSP core 2 sentence according to above-mentioned a certain method
Step is then no longer read out without message in shared drive 2 between disconnected DSP core, continues to perform the grades of DSP core 3 successively according to inspection
The operation whether being read out is surveyed, after a read, will be common between correspondence DSP core if corresponding DSP core has carried out read operation
The message identifier enjoyed in internal memory is set to 0.
Finally, the message that the DSP core in addition to DSP core 0 is read to it is handled accordingly.
Due to when in upper level DSP core be other DSP cores when, be at upper level DSP core be DSP core
The 0 descending handling process that issues is similar, and it is no longer repeated herein.
As shown in figure 3, the method for the interacting message of the embodiment of the present invention three is up to report handling process, including：
Step 300, the Digital Signal Processing DSP core in upper level in interface processing platform is next with being in by itself
The corresponding DSP core of level is shared and message package that report the need for existing in the shared drive of reporting message bag dump to itself with
In the shared shared drive in upper strata；And
Step 301, the message package in need reported in the local memory of the DSP core in upper level, then will be required
The message deposit to be reported is into itself and the shared shared drive in upper strata.
Wherein, required sequencing is not present in step 300 and step 301.
The report flow of message is illustrated by taking Fig. 2 as an example, wherein the DSP in upper level in interface processing platform
Core can be the DSP core 0 in Fig. 2, or any DSP core such as DSP core 1 or DSP core11.
If it is preferred that the upper strata in DSP core 0 is MAC layer, the DSP core 0 that is in has one.
When i.e. the DSP core in upper level is DSP core 0, only one of which DSP core is entered with MAC layer by shared drive 0

The up report flow of message is also to be carried out in preset time.Specifically, if a cycle for a frame when
Between, when in DSP core being DSP core 0 in interface processing platform, in first time slot of each frame, DSP core 0
Judge not store message in its shared drive 0, its determination methods is preferably comprised two schemes, but is not limited to both schemes：
One：DSP core 0 determine that the mark that interacts for the shared drive shared with MAC layer is represented and MAC layer shared drive
Message package is not stored；
Secondly：The cores of DSP core 0 detect that the message statistics number of the shared drive for the shared drive shared with MAC layer is 0.
If by judging, message is stored in shared drive 0, then continue to judge, until there is no message in shared drive 0, then
Proceed by report flow.
If by judging, message is not stored in shared drive 0, then in the 1st time slot, if existing in DSP core 0 needs
During the message package of report, DSP core 0 are stored in shared drive 0, if being not present in the 1st time slot, DSP core 0 needs
The message package to be reported, does not there is the message to be reported always within this time, then carries out next step.
It whether there is reporting message in the 2nd time slot DSP core 0 detect the shared drive 1 shared with DSP core 1
Bag, the message package reported in the absence of needs, then need not report, and carry out next step., will be shared interior if there is reporting message bag
The message in 1 is deposited to dump in shared drive 0.If in other DSP core 2 ... ..., DSP core N shared shared drive
Reported successively in the presence of the message package reported, the report flow class in the shared drive 1 that its flow is shared with DSP core 1
Seemingly, it will not be repeated here.
Wherein, reported it is preferred that detecting to whether there is in the shared drive 1 shared with DSP core 1 to DSP core 0
Message package, including but not limited to following two schemes：
DSP core 0 detect the mark that interacts for the shared drive shared with other DSP cores, and what expression presence to be reported disappears
Breath bag；Or
DSP core 0 detect that the message statistics number for the shared drive shared with other DSP cores is not 0.
The message station reported is stored to after shared drive 0 within the cycle, touched it is preferred that DSP core 0 are sent to MAC
Signal, notify there is the message package reported in MAC layer shared drive 0, MAC layer obtains message and then it is handled.
Then, in next cycle, then judged successively and reported.
As shown in figure 4, the exchange method of the message of the embodiment of the present invention four issue to be descending handling process when, including：
Step 400, message package is issued in the shared drive shared with DSP core 0 by MAC layer.
Step 401, the interacting message mark set for the shared drive shared with DSP core 0 is used to represent that this is shared by MAC layer
Message is deposited in internal memory, and sends trigger signal to DSP core 0 is used to notify DSP core 0 to handle the message package in the shared drive.
Step 402, after the trigger signal that the receiving mac layer of DSP core 0 is sent, read in the shared drive shared with MAC layer
Message, and the message is dumped in the local memory of DSP core 0.
Step 403, DSP core 0 is according to the attribute information of message in message package and the mapping relations of each DSP core, it is determined that pair
The DSP core that the message parsed is handled.
Step 404, if the corresponding DSP core of one or several message parsed is DSP core 0, the message is stayed in
DSP core 0 is handled；If the message parsed includes the message that needs other DSP cores correspondence DSP core is handled,
By message to be issued in the form of message package in the shared drive that its DSP core 0 is shared with other corresponding DSP cores.
Step 405, the DSP core in addition to DSP core 0 judges whether there is message in the shared drive shared with DSP core 0 successively
Bag, if so, performing step 406, otherwise performs step 407.
Step 406, each DSP core is obtained and the message in the message package in the shared drive of DSP core 0 and progress is corresponding one by one
Processing, the flow terminates.
Step 407, corresponding DSP core (in addition to DSP core 0) operates without obtaining, and the flow terminates.
As shown in figure 5, the interaction flow of the message of the embodiment of the present invention five report to be up handling process when, including：
Step 500, whether there is message package in the shared drive that the detection of DSP core 0 is shared with MAC layer, if without message package,
Step 501 is performed, step 503 is otherwise performed.
Step 501, DSP core 0 continues to detect in the shared drive shared with MAC layer whether there is message package, if when default
It is interior to have message package always, then step 503 is performed, step 502 is otherwise performed.
Step 502, DSP core 0 abandons reporting message bag, and the flow terminates.
Step 503, DSP core 0 turns the message package to be reported in local memory and other DSP cores message package to be reported
It is stored in the shared drive shared with MAC layer；
Step 504, dumped in the message package that DSP core 0 will be reported after the shared drive shared with MAC layer, to MAC layer
Sending trigger signal is used to notify MAC layer to read the message package in the shared drive.
Step 505, MAC layer receives trigger signal, and further detects the message for the shared drive shared with DSP core 0
Interaction mark is used to represent there is message package in the shared drive, reads the message package in the shared drive and is located accordingly
Reason, if being identified in the interacting message for further detecting the shared drive shared with DSP core 0 for representing do not have in the shared drive
There is message package, then do not carrying out obtaining step, the flow terminates.
