Description of the drawings
In order to more clearly explain the embodiment of the invention or the technical proposal in the existing technology, to embodiment or will show below
There is attached drawing needed in technology description to be briefly described, it should be apparent that, the accompanying drawings in the following description is only this
Some embodiments of invention for those of ordinary skill in the art without creative efforts, can be with
Obtain other attached drawings according to these attached drawings.
Fig. 1 is a kind of coupling message credit method for releasing flow diagram disclosed by the embodiments of the present invention；
Fig. 2 is that a kind of coupling message credit disclosed by the embodiments of the present invention discharges system structure diagram.
Specific implementation mode
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation describes, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other without creative efforts
Embodiment shall fall within the protection scope of the present invention.
The embodiment of the invention discloses a kind of coupling message credit method for releasing and systems, with the letter of release coupling message
With to the processing capacity at balance transmission end and receiving terminal.
Referring to Fig. 1, a kind of coupling message credit method for releasing provided in an embodiment of the present invention, including：
S101, the message that message output module is sent out is received；
S102, judge whether the message is coupling message；If so, execute S103, will it is described coupling message in it is every
Kind message caches by type, and records the type of message information of the coupling message；If it is not, then executing S101；
Specifically, when the message is not coupling message, instruction information is not added, and continues to processing output module hair
The next record message gone out.
Wherein, after the type of message information for recording the coupling message, including：
By each message addition coupling mark position in the coupling message.
Specifically, before message is cached by transmission channel, it can differentiate that this message is by type of message
It is no to belong to coupling message, if it is coupling message, then it will couple all types of messages that message includes and add coupling mark
Position, that is, the message for containing coupling flag bit are the messages coupled in message；Coupling message is cached respectively by type of message again
Into the subchannel packet buffer module of first in, first out.Wherein, in subchannel packet buffer module, different type message corresponds to
Caching it is mutual indepedent, when subsequent module reading process, dependence is not present each other.
Wherein, when coupling message write-in subchannel packet buffer module, the type of message information of message will be coupled, that is, wrapped
Information containing which kind message, while the coupling information logging modle of first in, first out is also written.
S104, according to the type of message information, judge whether each message of the coupling message is reported by each channel
Literary receiving module is read；
If so, executing S105, one credit of release to the message output module；If it is not, then continuing to execute S104.
Specifically, since all type of messages that coupling message is included share a credit, so only when coupling report
After all type of messages that text is included all are read processing, the release of this credit could be carried out, deadlock otherwise can be caused
Or messages be unable to get correct processing the phenomenon that such as overflow.
Wherein, according to the type of message information, judge whether each message of the coupling message is reported by each channel
Literary receiving module is read, including：
According to the type of message information, the corresponding coupling packet counting of each message in the coupling message is judged
Whether the numerical value of device is all higher than one；Wherein, the initial value of the coupling packet accouter is zero, and mark position is coupled when carrying
After message is read, then it will add one with the numerical value of the coupling packet accouter corresponding to the message that is read；
If so, each message of the judgement coupling message is read by each channel message receiving module.
Specifically, in message subchannel cache module, each type message channel is respectively provided with independent coupling message meter
Number devices, when the coupling information flag for the message being read is effective, then the corresponding coupling packet accouter of this type message
Numerical value add one, otherwise couple packet accouter numerical value remain unchanged.Wherein, it couples representated by packet accouter value,
Including the coupling message of the type message in this channel by subsequent module reading process, but corresponding coupling message credit is not
The quantity being released.Regulation coupling packet accouter initial value is 0, in order to make Counter Value not overflow, it is specified that its bit wide institute
The maximum counter value that can be represented, is not less than the maximum value of coupling information message credit.
And the type of message information in the present embodiment, coupling message is all recorded, so according to the suitable of first in, first out
Sequence judges all messages that the type of message information includes according to the type of message information that coupling information logging modle records
Whether the numerical value for coupling packet accouter is non-zero, if being non-zero, judges each message for coupling message by each logical
Road message receiving module is read, then discharges a coupling message credit, and enter and discharge arbitration process next time, otherwise, continue
It waits for until meeting release conditions.
Wherein, after discharging a credit to the message output module, including：
The numerical value of coupling packet accouter corresponding to each message in the coupling message is subtracted one, and will be described
Couple the type of message erasing of information of message.
Specifically, the record in coupling information logging modle in the present embodiment, it may be determined whether have been written into report
Literary subchannel cache module, but the basis for estimation that corresponding coupling credit does not discharge also.If coupling information logging modle is sky,
Show that there is no the coupling messages for needing release credit, otherwise enters coupling credit and discharge arbitration process.Therefore in release one
After credit to message output module, the numerical value of the coupling packet accouter corresponding to each message in the coupling message of release is subtracted
One, and the type of message information of the coupling message is read and abandoned from coupling information logging modle.
A kind of coupling message credit method for releasing provided in an embodiment of the present invention, including：Message output module is received to send out
Message；Judge whether the message is coupling message；If so, each message in the coupling message is delayed by type
It deposits, and records the type of message information of the coupling message；According to the type of message information, the every of the coupling message is judged
Whether kind message is read by each channel message receiving module；If so, release one credit to the message output module, can
See, in the present embodiment, after each message only in coupling message is read, can just be released to message output module one
Credit, to which just there are one credits to send next coupling message for message output module, to balance transmission end and receiving terminal
Processing capacity, not only resource overhead is few, but also realization method is simple.
A kind of coupling message credit release system provided in an embodiment of the present invention is introduced below, described below one
