Description

Technical Field

[0001] The embodiments of the present invention relate to the field of network communication technology, and in particular to a data processing method, apparatus, computer device, and computer-readable storage medium after a link anomaly. Background Technology

[0002] Existing SoC chips often include various devices. Some of these devices transmit data via links trained on them. If a link failure occurs during transmission, it can cause the entire system access path to become blocked. Access requests already received by some devices may not be able to respond promptly due to the link failure. Ultimately, recovery may be achieved by restarting the system based on link failure detection and recovery mechanisms, but this restart process will disrupt the operation of other devices. Therefore, the situation where the system access path becomes blocked due to a link failure cannot be effectively resolved. Summary of the Invention

[0048] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without inventive effort are within the scope of protection of this invention.

[0049] It should be noted that the descriptions involving "first," "second," etc., in the embodiments of the present invention are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by the present invention.

[0050] In the description of this invention, it should be understood that the numerical labels before the steps do not indicate the order in which the steps are performed, but are only used to facilitate the description of this invention and to distinguish each step, and therefore should not be construed as a limitation of this invention.

[0051] Example 1

[0052] Please see Figure 1 This document illustrates a flowchart of the data processing method following a link failure according to an embodiment of the present invention. It is understood that the flowchart in this embodiment is not intended to limit the order of execution steps. The data processing method following a link failure is applied to a system-on-a-chip (SoC). The SoC includes a response module, a routing module, and a recycle bin module. The following description uses the SoC as the execution entity as an example:

[0053] like Figure 1 As shown, the data processing method after a link anomaly may include steps S100 to S108, wherein:

[0054] Step S100: Obtain the link status of the link.

[0055] The link status includes a normal link status or an abnormal link status. The abnormal link status includes, but is not limited to, an abnormal link status such as a disconnected link status or an abnormal link status such as a data transmission error.

[0056] In an exemplary embodiment, the system-on-a-chip (SoC) includes multiple destination modules with link-layer data transmission capabilities. The destination modules receive and respond to access requests initiated by source modules through these link-layer data transmission capabilities. Step S100, which involves obtaining the link status of the link, further includes: the destination module receiving the access request from the source module obtaining the link status in real time. The link status includes whether the link is in a normal state or an abnormal state. In this embodiment, the SoC includes multiple functional modules and multiple destination modules. During data interaction, not every destination module is simultaneously transmitting data. Therefore, only the destination module receiving the access request needs to monitor and obtain the link status in real time. This not only reduces resource consumption but also allows for a corresponding response to the access request based on the real-time monitored link status. This effectively ensures that even when the SoC link malfunctions, the system data and control paths will not become stuck, and guarantees effective data transmission and interaction.

[0057] Step S102: If the link status of the link is in an abnormal state, the response module generates a first command based on the access request sent by the source module and sends the first command to the source module. The first command includes the link status and pre-configured data corresponding to the link status, which is used to instruct the source module to send subsequent access requests to the routing module when the link status is in an abnormal state.

[0058] To ensure that data transmission will not be interrupted even if a link failure occurs during data transmission, in an exemplary embodiment, the method further includes: pre-configuring a response module in each destination module. The pre-configuration of the response module includes: pre-configuring, according to user requirements, the response timing corresponding to the communication protocol between the source and destination modules when the link status is abnormal; and pre-configuring, according to each abnormal link status, an abnormal state corresponding to each abnormal link status and pre-configured data corresponding to each abnormal state. Combined with... Figure 2In this embodiment, a response module is configured in each destination module. Each response module includes a configuration module and a timing control module. The configuration module is used to set pre-configured codes or pre-configured specific characters to represent the abnormal conditions corresponding to different link states, based on the different abnormal conditions of the link state. The configuration module is also used to configure pre-configured data corresponding to each abnormal state according to the system-on-a-chip environment, for example, setting certain specific signal values ​​according to the system environment. During application, when the link state is in an abnormal state, the access request sent by the source module is remapped according to the determined abnormal state and the corresponding pre-configured data. A communication protocol for data interaction is pre-configured between each destination module and the corresponding source module. The timing control module is used in each destination module to configure the response timing corresponding to the access from the source module when the link state is in an abnormal state, based on user needs and the corresponding communication protocol, such as the read / write response timing of AXI. During application, when the link state is in an abnormal state, the access request sent by the source module is responded to according to the response timing determined by the communication protocol.

[0059] In an exemplary embodiment, each destination module is pre-configured with the response module. Step S102, which generates a first command based on the access request sent by the source module and sends the first command to the source module, may further include: obtaining a pre-configured response timing sequence corresponding to the communication protocol between the source module and the destination module based on the link status using the response module in the destination module; determining a pre-configured target abnormal state and corresponding pre-configured target data based on the link status; and responding to the access request according to the pre-configured response timing sequence corresponding to the source module based on the target abnormal state and the pre-configured target data, thereby generating the first command and sending the first command to the source module. In this embodiment, when the link is in an abnormal state, the timely response from the pre-configured response module in the destination module effectively avoids a deadlock in the internal transmission network (i.e., the data path). In other embodiments, if the link status is normal, the sending and receiving modules in the destination module process the access request sent by the source module according to the normal response timing sequence and return the corresponding response data to the source module.

[0060] Step S104: The routing module receives a new access request sent by the source module based on the first command. The new access request includes the link status, the pre-configured data, and the access request data.

[0061] Step S106: In the case that the link status is abnormal, the new access request is rewritten to generate a second command, and the second command is sent to the recycle bin module. The second command includes the link status, data obtained by converting the pre-configured data based on the pre-configured command rewriting rules, and the request data of the access request.

[0062] In an exemplary embodiment, step S106, which involves rewriting the new access request to generate a second command when the link state is abnormal, can also be achieved through the following operations: parsing the new access request when the link state is abnormal, determining the target communication protocol between the destination module sending the first command and the source module accessing the destination module; determining a pre-configured command rewriting rule corresponding to the target communication protocol from a plurality of pre-configured command rewriting rules based on the target communication protocol; and rewriting the new access request based on the pre-configured command rewriting rule corresponding to the target communication protocol to generate the second command. Combined with... Figure 3 In this embodiment, the routing module is used for state resolution, command caching, command rewriting, and command sending. The routing module receives new access requests from the source module, parses the request, and if it finds that the current link state is abnormal, it rewrites the new access request according to the command rewriting rules determined by the communication protocol, such as address mapping rewriting rules, and generates a second command. Even if the current link state is abnormal, the access request is still processed according to the set command rewriting rules to prevent the system's data path from becoming blocked.

[0063] In an exemplary embodiment, the method further includes: when the link status of the link is abnormal, if the same destination module receives multiple access requests sent by multiple source modules within a preset time period, the same destination module responds to the multiple access requests respectively to obtain a first command corresponding to each of the multiple access requests, and returns the multiple access requests to their respective source modules; and the routing module receives new access requests generated and sent by the multiple source modules based on the corresponding first commands, caches the multiple new access requests, and processes the multiple new access requests sequentially according to the order in which they are received. In this embodiment, when the routing module receives new access requests generated by multiple source modules responding to multiple first commands sent by the same destination module within a short time period or a preset time period, and the requests received by the routing module in chronological order are still being processed before the subsequent requests are processed, the multiple new access requests are cached in an orderly manner to facilitate orderly processing later, effectively improving data processing efficiency and system stability.

[0064] In an exemplary embodiment, sending the second command to the recycle bin module further includes: when the link status is abnormal, determining the recycle bin module and the corresponding sending path based on the corresponding routing rules, and sending the second command to the recycle bin module according to the sending path. In this embodiment, there can be multiple sending paths. Based on the system-on-a-chip's environment, resources, load, and other conditions, the corresponding routing rules and sending paths can be flexibly configured in advance by software, facilitating data transmission during the application process.

[0065] Step S108: The recycling module responds to the second command to obtain response data, and then returns the response data to the source module.

[0066] In this embodiment, a recycle bin module is set up so that even if the link is in an abnormal situation, the recycle bin module can respond to the access request of the source module in a timely manner and indicate to the source module that the current link is in an abnormal situation through the returned response data.

[0067] This embodiment has at least the following beneficial effects: By setting the recycle bin module to respond promptly to the commands of the source module when the link is abnormal, as well as the data transmission of the response module, routing module and recycle bin module, it can effectively solve the problem of the entire system's data path being stuck when the link of the system-on-a-chip fails during data transmission (e.g., the link is disconnected). Without restarting the system chip and without affecting the operation of other devices, it can also respond to the access requests of the source module when the link is abnormal, effectively forming a data path protection mechanism for link abnormalities, ensuring data processing efficiency and system stability.

[0071] The acquisition module 400 is used to acquire the link status of the link;

[0072] An anomaly response module 402 is used to generate a first command based on the access request sent by the source module if the link status of the link is in an abnormal situation, and send the first command to the source module. The first command includes the link status and pre-configured data corresponding to the link status, which is used to instruct the source module to send subsequent access requests to the routing module when the link status is in an abnormal situation.

The second command includes the link status, data obtained by transforming the pre-configured data based on pre-configured command rewriting rules, and the request data of the access request.

[0075] The recycle bin module response module 408 is used to respond to the second command through the recycle bin module to obtain response data and return the response data to the source module.
