Description

Technical Field

[0001] This invention relates to the field of information technology, and in particular to a request processing method, system, storage medium, and device. Background Technology

[0002] With the widespread application of multi-core processors in the data domain, the efficiency of system buses is receiving increasing attention. In the existing CHI protocol coherent system bus, after the sender (rn) releases a read request, it receives a response from the receiver (hn). Then, rn sends a packet response, sending the response message to hn. The CHI protocol is the fifth generation of AMBA and can be considered an evolution of the ACE protocol. It uses packets to transmit all information, with each packet containing different information across various domains. Essentially, it still aims to solve the data consistency problem between multiple CPUs (rn).

[0003] The main drawback of existing technologies is the long read request process, which includes read request, read response, and response confirmation. This process increases the bandwidth requirements for data and prolongs the time for hn to release read request resources, making it impossible to release the resources allocated by hn, thereby affecting the efficiency and performance of the overall protocol. Summary of the Invention

[0004] In view of this, the purpose of this invention is to provide a request processing method, system, storage medium, and device to solve the problem of long request processing time in the prior art in the CHI protocol.

[0005] To achieve the above objectives, the present invention provides a request processing method, comprising the following steps:

[0006] A first request is sent from the first sending end to the receiving end, and a second request is sent from the second sending end to the receiving end;

[0007] In response to the receiving end receiving the second request, the receiving end sends a first listening message to the first sending end based on the listening directory of the receiving end, and obtains the listening result that the first sending end has issued the first request based on the first listening message, and sets the first collision flag of the first sending end to the bit based on the listening result.

[0008] In response to the setting of the first collision flag at the first transmitting end, a first collision response is generated and sent to the receiving end;

[0009] In response to the receiving end receiving the first conflict response and the first request not being processed, the second request is processed.

[0010] In some embodiments, the method further includes:

[0011] In response to the completion of the second request processing, a processing completion message is generated and sent to the second sender.

[0012] In some embodiments, the method further includes:

[0013] In response to the receiving end receiving the first request, a second listening message is sent to the second sending end.

[0014] In some embodiments, the method further includes:

[0015] In response to the completion message arriving at the second sender before the second listening message, the second sender generates a listening response based on the second listening message and sends the listening response to the receiver.

[0016] The receiving end sends the listening response to the first sending end, and the first sending end generates a first conflict request based on the listening response and the result of setting the first conflict flag, and sends the first conflict request to the receiving end.

[0017] In response to the receiving end receiving the first conflict request, an invalid conflict response is generated based on the first conflict request and sent to the first sending end.

[0018] In some embodiments, the method further includes:

[0019] In response to the second listening message arriving at the second sender before the message is processed, the second collision flag of the second sender is set, and the second sender generates a second collision response and sends it to the receiver.

[0020] In response to the receiving end receiving the second conflict response and the second request having been processed, the request source and request code ID of the second request are recorded;

[0021] In response to the completion of recording at the receiving end, the second sending end generates a second conflict request and sends the second conflict request to the receiving end;

[0022] In response to the receiving end receiving the second conflict request, a conflict monitoring message is sent to the second sending end;

[0023] In response to the second sending end receiving a conflict monitoring message, it sends a conflict monitoring response based on the second request to the receiving end, and the receiving end processes the first request based on the received conflict monitoring response.

[0024] In some embodiments, the method further includes:

[0025] In response to the completion of the second request processing, the resources of the receiving end used during the processing of the second request are released.

[0026] In some embodiments, sending a first listening message to a first sending end based on the listening directory of the receiving end includes:

[0027] By querying the receiver's listening directory, the receiver obtains the result of listening to the first sender, and sends the first listening message to the first sender based on the result.

[0028] Another aspect of the present invention provides a request processing system, comprising:

[0029] The request sending module is configured to send a first request to the receiving end through a first sending end, and to send a second request to the receiving end through a second sending end;

[0030] The conflict flag setting module is configured to respond to the receiving end receiving a second request, send a first listening message to the first sending end based on the listening directory of the receiving end, obtain the listening result that the first sending end has issued a first request based on the first listening message, and set the first conflict flag setting of the first sending end based on the listening result.

[0031] The collision response module is configured to respond to a first collision flag setting at the first transmitting end, generate a first collision response, and send the first collision response to the receiving end; and

[0032] The request processing module is configured to process a second request in response to the receiving end receiving a first conflict response and the first request not being processed.

[0033] In another aspect, the present invention provides a computer-readable storage medium storing computer program instructions that, when executed by a processor, implement any of the methods described above.

[0034] In another aspect, the present invention provides a computer device including a memory and a processor, wherein the memory stores a computer program that, when executed by the processor, performs any of the methods described above.

[0035] The present invention has at least the following beneficial technical effects:

[0036] This invention sets a conflict flag at the sending end and generates a conflict response after the conflict flag is set, which is then sent to the receiving end. This allows the receiving end to know in a timely manner whether there is a conflict in the request, avoiding the need to wait for each request to arrive at the receiving end to know that a conflict has occurred when there is a conflict between requests in the prior art. This saves request processing time and improves request processing efficiency. Attached Figure Description

[0042] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be further described in detail below with reference to specific examples and the accompanying drawings.

[0043] It should be noted that all uses of "first" and "second" in the embodiments of the present invention are for the purpose of distinguishing two different entities or different parameters with the same name. Therefore, "first" and "second" are merely for convenience of expression and should not be construed as limiting the embodiments of the present invention. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion, such as other steps or units inherent in a process, method, system, product, or device that includes a series of steps or units.

[0044] Based on the above objectives, a first aspect of the present invention provides an embodiment of a request processing method. Figure 1 The diagram shown is a schematic representation of an embodiment of the request processing method provided by the present invention. Figure 1 As shown, the embodiments of the present invention include the following steps:

[0045] Step S10: Send a first request to the receiving end through the first sending end, and send a second request to the receiving end through the second sending end;

[0046] Step S20: In response to the receiving end receiving the second request, the receiving end sends a first listening message to the first sending end based on the listening directory of the receiving end, and obtains the listening result that the first sending end has issued the first request based on the first listening message, and sets the first conflict flag of the first sending end to the bit based on the listening result.

[0047] Step S30: In response to the first collision flag being set at the first transmitting end, a first collision response is generated and sent to the receiving end;

[0048] Step S40: In response to the receiving end receiving the first conflict response and the first request not being processed, process the second request.

[0049] This invention provides an embodiment of the invention that sets a conflict flag at the sending end and generates a conflict response to the receiving end after the conflict flag is set. This allows the receiving end to know in a timely manner whether there is a conflict in the request, avoiding the need to wait for each request to arrive at the receiving end to know that a conflict has occurred when there is a conflict between requests in the prior art. This saves request processing time and improves request processing efficiency.

[0050] In some embodiments, the method further includes: generating a processing completion message in response to the completion of the second request processing, and sending the processing completion message to the second sender.

[0051] In some embodiments, the method further includes: in response to the receiving end receiving the first request, sending a second listening message to the second sending end.

[0052] In some embodiments, the method further includes: in response to a processing completion message arriving at a second sending end before a second listening message, generating a listening response based on the second listening message at the second sending end, and sending the listening response to a receiving end; the receiving end sending the listening response to a first sending end, generating a first conflict request based on the listening response and the result of setting a first conflict flag at the first sending end, and sending the first conflict request to the receiving end; in response to the receiving end receiving the first conflict request, generating an invalid conflict response based on the first conflict request, and sending the invalid conflict response to the first sending end.

[0053] In some embodiments, the method further includes: in response to the second listening message arriving at the second sending end before the processed message, setting the second conflict flag of the second sending end, and generating a second conflict response and sending it to the receiving end; in response to the receiving end receiving the second conflict response and the second request having been processed, recording the request source and request code ID of the second request; in response to the receiving end completing the recording, generating a second conflict request by the second sending end and sending the second conflict request to the receiving end; in response to the receiving end receiving the second conflict request, sending a conflict listening message to the second sending end; in response to the second sending end receiving the conflict listening message, sending a conflict listening response based on the second request to the receiving end, and processing the first request by the receiving end based on the received conflict listening response.

[0054] In this embodiment, ID represents an identification number and is unique. The request code ID is the identification number of each request in the request source.

[0055] In some embodiments, the method further includes: releasing the resources of the receiving end used during the processing of the second request in response to the completion of the second request processing.

[0056] In this embodiment, after the second request is processed, the resources used by the receiving end are released, and then the first request uses those resources for processing.

[0057] In some embodiments, sending a first listening message to a first sending end based on the listening directory of the receiving end includes: obtaining the result of the receiving end listening to the first sending end by querying the listening directory of the receiving end, and sending a first listening message to the first sending end based on the result.

[0058] The following is an exemplary embodiment based on the above embodiments:

[0059] 1) rn0 (first sender) sends a read request req0 (first request) to hn (receiver), and rn1 (second sender) sends a read request req1 (second request) to hn;

[0060] 2) If req1 arrives at hn first and finds that hn's listening directory needs to listen to rn0, then hn sends the first SNP listening message to rn0. Since rn0 has a req0 read request that is being sent, a conflict occurs. Therefore, the first conflict flag in rn0 will be set, and the first conflict response will be returned. When hn receives the first conflict response sent by rn0 and req0 has not yet been executed, it sends the response of req1. At this time, req1 releases resources in hn and begins to process the request of req0.

[0061] 3) When hn receives the req0 request, it sends the second SNP listening message to rn1. If the second SNP listening message arrives at rn1 later than the response message (processing completion message) of req1, then rn1 returns a listening response. After receiving the listening response returned by rn1, hn sends a response to req0 of rn0. After receiving the response, rn0 sends the first conflict request because the first conflict flag is set. Since req1 and req0 have already been completed by hn, hn directly returns an invalid conflict response to this first conflict request.

[0062] 4) If the second SNP listening message arrives at rn1 faster than the response message (processing completion message) of req1, a conflict occurs because rn1 has not yet received a response to its req1 request. In this case, the second conflict flag in rn1 will be set, and a second conflict response will be returned. When hn receives the second conflict response from rn1 and rn1 has already completed its execution, it will record the request source and request code ID of req1 in hn. After rn1 receives the response, it sends a second conflict request. After hn receives this second conflict request, it sends a conflict listening message to rn1. After rn1 receives the conflict listening message, it sends a conflict listening response. After hn receives rn1's req1 conflict listening response, it sends a response to req0.
