Fig. 2 is the disclosed a kind of coupling message credit delivery system structural representation of the embodiment of the present invention.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
The embodiment of the invention discloses a kind of coupling message credit method for releasing and system, to discharge the credit of coupling message, thus the disposal ability of balance transmitting terminal and receiving terminal.
See Fig. 1, the one coupling message credit method for releasing that the embodiment of the present invention provides, comprising:
The message that S101, reception message output module send;
S102, judge that whether described message is coupling message; If so, then perform S103, by the often kind of message buffer memory by type in described coupling message, and record the type of message information of described coupling message; If not, then S101 is performed;
Concrete, when this message is not coupling message, do not add indication information, and continue to receive the next record message processing output module and send.
Wherein, after recording the type of message information of described coupling message, comprising:
Each message in described coupling message is added coupling and indicates position.
Concrete, before message carries out buffer memory by transmission channel, can differentiate whether this message belongs to coupling message by type of message, if coupling message, then all types of messages that coupling message comprises all are added coupling flag bit, the message namely containing coupling flag bit is all the messages in coupling message; Again by coupling message by type of message respectively buffer memory enter the subchannel packet buffer module of first-in first-out.Wherein, in subchannel packet buffer module, the buffer memory that dissimilar message is corresponding is separate, during subsequent module reading process, and not Existence dependency relationship each other.
Wherein, when the message that is coupled writes subchannel packet buffer module, by the type of message information of coupling message, namely comprise the information which plants message, also write the coupling information logging modle of first-in first-out simultaneously.
S104, according to described type of message information, judge whether often kind of message of described coupling message is all read by each passage message receiver module;
If so, S105, release credit is then performed to described message output module; If not, then continue to perform S104.
Concrete, the all type of messages comprised due to coupling message share a credit, so after only having all type of messages comprised when coupling message to be all read process, just can carry out the release of this credit, otherwise the message such as deadlock or spilling can be caused cannot to obtain the phenomenon of correct process.
Wherein, according to described type of message information, judge whether often kind of message of described coupling message is all read by each passage message receiver module, comprising:
According to described type of message information, judge whether the numerical value of the coupling packet accouter that each message in described coupling message is corresponding is all greater than one; Wherein, the initial value of described coupling packet accouter is zero, after the message carrying coupling sign position is read, then adds one by with the numerical value of the packet accouter that is coupled corresponding to the message be read;
If so, then judge that often kind of message of described coupling message is all read by described each passage message receiver module.
Concrete, in message subchannel cache module, every type message passage all arranges the packet accouter that is independently coupled, when the coupling information flag of the message be read is effective, then the numerical value of the coupling packet accouter that this type message is corresponding adds one, otherwise the numerical value of coupling packet accouter remains unchanged.Wherein, representated by coupling packet accouter value, the coupling message comprising the type message at this passage by subsequent module reading process, but the undelivered quantity of coupling message credit of correspondence.Regulation coupling packet accouter initial value is 0, in order to make Counter Value overflow, specifies the maximum counter value that its bit wide can represent to be not less than the maximum of coupling information message credit.
And in the present embodiment, the type of message information of coupling message is all recorded, so according to the order of first-in first-out, according to the type of message information of coupling information logging modle record, judge whether the numerical value of the coupling packet accouter of all messages that this type of message information comprises is non-zero, if be non-zero, then judge that often kind of message of coupling message is all read by each passage message receiver module, then discharge a coupling message credit, and enter and discharge arbitration process next time, otherwise, continue to wait for until meet release conditions.
Wherein, after discharging a credit to described message output module, comprising:
The numerical value of the coupling packet accouter corresponding to each message in described coupling message is all subtracted one, and by the type of message erasing of information of described coupling message.
Concrete, the record in the present embodiment in coupling information logging modle, can determine whether there is and write message subchannel cache module, but the basis for estimation that the coupling credit of correspondence does not also discharge.If coupling information logging modle is empty, show not exist the coupling message needing to discharge credit, otherwise enter coupling credit release arbitration process.Therefore after release credit to message output module, the numerical value of the coupling packet accouter in the coupling message of release corresponding to each message is subtracted one, and the type of message information of this coupling message is read from coupling information logging modle and abandons.
The one coupling message credit method for releasing that the embodiment of the present invention provides, comprising: receive the message that message output module sends; Judge whether described message is coupling message; If so, then by the often kind of message buffer memory by type in described coupling message, and the type of message information of described coupling message is recorded; According to described type of message information, judge whether often kind of message of described coupling message is all read by each passage message receiver module; If, then discharge a credit to described message output module, visible, in the present embodiment, after only having each message in coupling message to be all read, just can discharge to message output module credit, thus message output module just has a credit to send next coupling message, thus the disposal ability of balance transmitting terminal and receiving terminal, not only resource overhead is few, and implementation is simple.
Be introduced the one coupling message credit delivery system that the embodiment of the present invention provides below, one coupling message credit delivery system described below is coupled message credit method for releasing with above-described one can be cross-referenced.
