Example 1

Referring to fig. 1, a flowchart of steps of a method for processing data after a link failure according to an embodiment of the present invention is shown. It will be appreciated that the flow charts in the method embodiments are not intended to limit the order in which the steps are performed. The data processing method after the link abnormality is applied to a system-on-chip (SOC) chip. The system-on-chip comprises a response module, a routing module and a recycle bin module. The following description is made by taking a system-in-chip as an execution body, specifically as follows:

as shown in fig. 1, the method for processing data after link abnormality may include steps S100 to S108, in which:

step S100, obtaining a link state of the link.

Wherein the link state includes the link state being in a normal condition or the link state being in an abnormal condition, the link state being in an abnormal condition including but not limited to: abnormal conditions in which the link is in disconnection, abnormal conditions in which the link is in data transmission errors, and the like.

In an exemplary embodiment, the system-on-chip includes a plurality of destination modules with link layer data transmission functions; the destination module receives and responds to the access request initiated by the source module through the link layer data transmission function. The step S100 of obtaining the link state of the link further includes: and acquiring the link state of the link in real time through a destination module which receives the access request sent by the source module, wherein the link state comprises the link state in a normal condition or the link state in an abnormal condition. In this embodiment, the system-level chip includes a plurality of functional modules and a plurality of destination modules, and in the process of performing data interaction, not every destination module performs data transmission interaction at the same time, so that only the destination module that receives the access request needs to monitor and acquire the link state of the link in real time, which not only reduces occupation of resources, but also can respond to the access request according to the link state obtained by real-time monitoring, thereby effectively ensuring that system data and control channels are not suspended when the link of the system-level chip is abnormal, and ensuring effective transmission and interaction of the data.

Step S102, if the link state of the link is in an abnormal condition, generating, by the response module, a first command based on the access request sent by the source module, and sending the first command to the source module, where the first command includes the link state and preconfigured data corresponding to the link state and used for instructing the source module to send a subsequent access request to the routing module when the link state is in an abnormal condition.

In order to realize that the link abnormality does not cause the data path of the system to hang up in the data transmission process, in an exemplary embodiment, the method further includes: pre-configuring a response module in each destination module, wherein the pre-configuring of the response module comprises: configuring a response time sequence corresponding to a communication protocol between the source module and the destination module under the condition that a link state is abnormal in advance according to user requirements; and configuring an abnormal state corresponding to each abnormal condition of the link state and pre-configuration data corresponding to each abnormal state in advance according to each abnormal condition of the link state. Referring to fig. 2, in this embodiment, a response module is configured in each destination module, and each response module includes a configuration module and a timing control module. The configuration module is used for setting pre-configuration codes or pre-configuration specific characters according to abnormal conditions of different link states so as to represent the abnormal conditions corresponding to the link states, and is also used for configuring pre-configuration data corresponding to each abnormal state according to the environment of the system-in-chip, for example, setting certain specific signal values according to the environment of the system. In the application process, when the link state is in an abnormal condition, the access request sent by the source module is remapped according to the determined abnormal state and the corresponding preconfigured data. The system comprises a plurality of destination modules, a source module, a time sequence control module and a link state management module, wherein a communication protocol for data interaction is pre-configured between each destination module and the corresponding source module, and the time sequence control module is used for configuring a response time sequence corresponding to the access of the source module, such as a read-write response time sequence of an AXI, in each destination module according to the requirements of users and the corresponding communication protocol under the condition that the link state is abnormal. In the application process, when the link state is in an abnormal condition, responding to the access request sent by the source module according to the response time sequence determined by the communication protocol.

In an exemplary embodiment, each of the destination modules is preconfigured with the response module; the step S102 of generating, by the response module, a first command based on the access request sent by the source module, and sending the first command to the source module may further include: acquiring a pre-configuration response time sequence corresponding to a communication protocol between the source module and the destination module through a response module in the destination module according to the link state; determining a preconfigured target abnormal state and corresponding preconfigured target data based on the link state; and responding to the access request according to a pre-configuration response time sequence corresponding to the source module based on the target abnormal state and the pre-configuration target data so as to generate the first command, and sending the first command to the source module. In this embodiment, when the link is in an abnormal condition, the link responds in time according to the configured response module in the destination module, so as to effectively avoid the condition that the transmission network (i.e. the data path) inside the system is dead. In other embodiments, if the link state is in a normal state, the sending module and the receiving module in the destination module process the access request sent by the source module according to the conventional response time sequence, and return the corresponding response data to the source module.

Step S104, receiving, by the routing module, a new access request sent by the source module based on the first command, where the new access request includes the link state, the preconfigured data, and request data of the access request.

And step S106, when the link state of the link is abnormal, rewriting the new access request to generate a second command, and sending the second command to the recycle bin module, wherein the second command comprises the link state, data obtained by converting the preconfigured data based on a preconfigured command rewriting rule and request data of the access request.

In an exemplary embodiment, the step S106 of overwriting the new access request to generate the second command in the case that the link state of the link is abnormal may be further obtained by: analyzing the new access request under the condition that the link state of the link is abnormal, and determining a target communication protocol between a destination module for sending the first command and a source module for accessing the destination module; determining a preconfigured command rewrite rule corresponding to the target communication protocol from a plurality of preconfigured command rewrite rules based on the target communication protocol; and rewriting the new access request based on a pre-configured command rewrite rule corresponding to the target communication protocol to generate the second command. Referring to fig. 3, in this embodiment, the routing module is used for state parsing, command buffering, command rewriting, and command sending. The routing module receives the new access request sent by the source module, analyzes and obtains that the current link state is in an abnormal condition, rewrites the new access request according to a command rewrite rule determined by the communication protocol, such as an address mapping rewrite rule and the like, and converts the new access request into a second command. Even if the current link state is in abnormal condition, the access request is processed according to the set command rewrite rule, and the condition that the data path of the system is suspended is avoided.

In an exemplary embodiment, the method further comprises: if the link state of the link is abnormal, if the same destination module receives access requests sent by a plurality of source modules within a preset time period, respectively responding to the plurality of access requests through the same destination module to obtain first commands respectively corresponding to the plurality of access requests, and respectively returning the plurality of access requests to the corresponding source modules; and receiving new access requests generated and sent by the source modules based on the corresponding first commands through the routing module, caching the new access requests, and sequentially processing the new access requests according to the sequence of receiving the new access requests. In this embodiment, when the routing module receives new access requests generated by a plurality of source modules respectively responding to a plurality of first commands sent by the same destination module within a short time period or within a preset time period, and the routing module processes the requests received after the first requests according to the time sequence, the routing module processes the requests received after the first requests, and sequentially caches the plurality of new access requests, so that sequential processing is facilitated, and data processing efficiency and system stability are effectively improved.

In an exemplary embodiment, the sending the second command to the recycle bin module further includes: and under the condition that the link state of the link is abnormal, determining the recycle bin module and a corresponding sending path based on a corresponding routing rule, and sending the second command to the recycle bin module according to the sending path. In this embodiment, the transmission paths may be multiple, and the routing rule and the corresponding transmission path of the response may be flexibly configured in advance by software based on the environment, the resource, the load, and the like of the system-in-chip, so that data transmission in the application process is facilitated.

And step S108, responding to the second command through the recycle bin module to obtain response data, and returning the response data to the source module.

In this embodiment, a recycle bin module is provided, and even if the link is in an abnormal condition, the recycle bin module can timely respond to an access request of the source module, and the source module is prompted that the current link is in an abnormal condition through returned response data.

The embodiment has at least the following advantages: by setting the command of the source module and the data transmission of the response module, the routing module and the recycle station module when the link is abnormal, the situation that the data path of the whole system is blocked after the link is abnormal (for example, the link is disconnected) in the data transmission process of the system-level chip can be effectively solved, the system chip is not required to be restarted, and on the premise that the work of other equipment is not influenced, the access request of the source module can be responded when the link is abnormal, the data path protection mechanism of the link is effectively formed, and the data processing efficiency and the stability of the system are ensured.
