[0026] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. When the following description refers to the drawings, identical numerals in different figures represent identical or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.
[0027] The block diagrams shown in the accompanying drawings are merely functional entities and do not necessarily correspond to physically separate entities. That is, these functional entities may be implemented in software, in one or more hardware modules or integrated circuits, or in different networks and / or processor devices and / or microcontroller devices.
[0028] The flowcharts shown in the accompanying drawings are for illustrative purposes only and do not necessarily include all contents and operations / steps, nor must they be executed in the order described. For example, some operations / steps may be decomposed, while others may be combined or partially combined. Therefore, the actual execution order may vary depending on the actual situation.
[0029] In this application, "plurality" refers to two or more. "And / or" describes the relationship between related objects, indicating that three possible relationships exist. For example, "A and / or B" can mean: A exists alone, A and B exist simultaneously, and B exists alone. The character " / " generally indicates that the related objects are in an "or" relationship.
[0030] A multi-core controller has a main core and at least one auxiliary core. The main core has a built-in storage module or an external storage module. Each auxiliary core reads the corresponding data directly from the storage module to perform local operations and realize the corresponding application functions. This makes the storage module less stable and prone to data loss, causing the auxiliary core to fail to read data and unable to guarantee the operation of the auxiliary core's basic functions.
[0031] To this end, one aspect of the present application provides a data processing method for a multi-core controller. Figure 1 , Figure 1 This is a flow chart of a data processing method for a multi-core controller, shown as an exemplary embodiment of the present application. The multi-core controller includes a primary core and a secondary core, the primary core includes an agent module, and the data processing method is applied to the primary core and includes at least steps S110 to S120, as detailed below: S110: In response to the read request of the auxiliary core, calling the proxy module to perform a read operation on the storage module.
[0032] The auxiliary core is the initiator of the read request. This application does not limit the number of auxiliary cores, and there can be multiple auxiliary cores.
[0033] The proxy module can be understood as a virtual program, such as a proxy application, within the primary core, or as a proxy port. It serves as a communication bridge between the primary and secondary cores, managing read requests from each secondary core. The primary core accesses relevant storage data from the storage module through the proxy module to prevent multiple secondary cores from directly accessing the storage module, which could lead to storage module instability. Interaction with the storage module through the proxy module ensures storage module stability.
[0034] like Figure 2 As shown, Figure 2 The main core and each auxiliary core can communicate with each other, and each auxiliary core can send a read request to the main core to read the storage data in the storage module connected to the main core. The storage module can be as follows: Figure 2 The device shown is external to the multi-core controller and can be considered a solid-state memory, such as a hard drive. When the multi-core controller is powered on, the primary core sequentially boots, initializes each module, and connects to the storage module. After the OS completes execution, it issues a synchronization boot command to the other secondary cores. Upon receiving the boot command, the secondary cores begin initialization. During initialization, the secondary cores read the values in the storage module connected to the primary core.
[0035] S120 : Upon receiving a first return value representing a reading result, the proxy module is called to send the first return value to the auxiliary core, so that the auxiliary core determines whether to perform a local operation based on a local preset value based on the first return value.
[0036] The first return value includes a read result indicating a successful read and a read result indicating a failed read (e.g., 0x1 for a successful read and 0x2 for a failed read). The default local value is the auxiliary core's own value and serves as a fallback to prevent the auxiliary core's basic functions from being lost due to a read failure, effectively ensuring the operation of the auxiliary core's basic functions.
[0037] If the first return value is a read result indicating a successful read, the proxy module returns the first return value to the slave core and also returns the read value obtained from the storage module to the slave core. The slave core can determine whether the data read was successful or failed based on the first return value. If the read was successful, the slave core performs a local operation based on the read value; if the read failed, the slave core performs a local operation based on a preset value.
[0038] This embodiment uses a proxy module in the main core to read data from the storage module, thereby preventing multiple auxiliary cores from accessing the storage module simultaneously and causing a decrease in storage module stability. The proxy module can return a first return value representing the read result to the corresponding auxiliary core, so that the auxiliary core can determine whether to perform a local operation based on a local preset value based on the first return value. This embodiment introduces the local preset value as a fallback execution value to avoid the loss of basic auxiliary core functions due to read failures, thereby effectively ensuring the operation of the auxiliary core's basic functions.
[0039] In another exemplary embodiment, the main core can also respond to the write request of the auxiliary core. For details, please refer to Figure 3 , Figure 3 is based on Figure 1 The exemplary embodiment shown is a flow chart of another data processing method for a multi-core controller. Figure 1 Based on S110 to S120 shown, at least S310 to S320 are also included. The auxiliary core includes multiple applications, which are described in detail as follows: S310: In response to a write request from a designated application in the auxiliary core, calling an agent module to perform a write operation on a storage module; wherein the write request includes a write value.
[0040] Each slave core contains at least one application, and different applications can initiate read and write requests to the primary core. It's important to note that different applications in the same slave core cannot initiate read and / or write requests concurrently. They must initiate them sequentially, for example, sending requests to the primary core in the order they were initiated.
[0041] The proxy module in this embodiment has the functions of both reading and writing data. The proxy module can write the write value in the write request into the storage module so that the write value is used as storage data.
[0042] S320: Upon receiving the second return value representing the write result, the calling proxy module returns the second return value to the designated application, so that the designated application determines whether to perform a local operation based on the write value based on the write result represented by the second return value.
[0043] Similarly, the second return value includes a write result value indicating a successful write and a write result value indicating a write failure. For example, 0x3 indicates a successful write, and 0x4 indicates a write failure. The designated application in the auxiliary core can determine the success or failure of the data write based on the second return value. If the write is successful, the designated application in the auxiliary core performs local operations based on the written value; if the write fails, the auxiliary core stops executing local operations.
[0044] In some embodiments, the master core also monitors the number of write requests to avoid responding to frequent write requests from the same source. Specifically, if the number of write requests received from a specified application exceeds a preset number within a first preset time period, the write function of the specified application is restricted. By monitoring write requests from the same source and, if corresponding penalty conditions are met, restricting writes to the specified application, this ensures that the storage module is not frequently operated, thereby improving the stability of the storage module.
[0045] Among them, the first preset duration can be a preset number of proxy cycles. This application does not limit its specific duration, and it can be adaptively adjusted according to actual scenario requirements.
[0046] In another exemplary embodiment of the present application, how to record the corresponding situation of the relevant request is described in detail. Figure 4 , Figure 4 is based on Figure 1 、 Figure 3 A flowchart of another data processing method for a multi-core controller according to any of the exemplary embodiments shown in FIG. The data processing method further includes S410 ; wherein the multi-core controller further includes a recording module, which is described in detail as follows: S410: In response to a read request, the read interface corresponding to the read request is sent to the recording module, so that when the recording module receives the first return value generated by the storage module, it generates an operation and maintenance record reflecting the response status of the read request based on the read interface and the first return value.
[0047] The recording module can be a module independent of the main core and the auxiliary core, or it can be an application with a recording function placed in the main core or the related auxiliary core, and this application does not limit it.
[0048] like Figure 5 As shown, Figure 5 This is a schematic diagram of a data processing scenario for a multi-core controller, shown in an exemplary embodiment of the present application. RTE_Redata represents the read interface, RTE_Wrdata represents the write interface, and Return_code represents the return value, which can be either the first return value (i.e., a value indicating read success / failure) or the second return value (i.e., a value indicating write success / failure). Figure 5 The multi-core controller in Figure 1 The multi-core controller shown in FIG. 1 further includes a recording module. The proxy module can send the read interface corresponding to the read request to the recording module. The RTE layer between the proxy module and the storage module sends the obtained first return value to the recording module. The recording module can generate an operation and maintenance record that fully reflects the response status of the read request based on the read interface and the first return value. In some embodiments, the read value can also be sent to the recording module for recording.
[0049] Similarly, the recording module can also fully record the response status of the write request, referring to the recording method of the response status of the read request, which will not be repeated in this application.
[0050] This embodiment introduces a recording module to completely record the responses to read requests and write requests, so as to facilitate tracing relevant data during problem analysis and improve data traceability.
[0051] In another exemplary embodiment of the present application, a method for preventing data from being overwritten is described in detail. Figure 6 , Figure 6 is based on Figure 1 、 Figure 3 、 Figure 4 The exemplary embodiment shown in any one of the flowcharts of another multi-core controller data processing method. The data processing method at least includes S610 to S620, which are described in detail as follows: S610: When power-on is successful and the current pending request is a write request, determine whether to respond to the current pending request based on historical return values.
[0052] Each time the main core is powered on, if the current pending request (i.e., the request that needs to be responded to immediately after power-on) is a write request, it is necessary to analyze the operation request at the last power-off, that is, to determine whether the last operation request was a read request based on the historical return value, and thus determine whether to respond to the current pending request.
[0053] S620: If the historical return value is the first return value, and the read result indicates a successful read, respond to the current pending request.
[0054] If the historical return value is the second return value, it indicates that a data writing operation was performed on the storage module before the power was turned off last time. If a writing operation is performed on the storage module again, the last written data will be overwritten.
[0055] If the historical return value is the first return value and the read result indicates a successful read, it indicates that a data read operation was performed on the storage module before the last power-off, and the storage module includes valid data that can be read. If the current power-on is successful, a write request can be responded to to perform a write operation on the storage module.
[0056] By analyzing the historical return value after each power-on, it is determined whether to respond to the current pending request which is a write request, so as to avoid the valid data in the storage module being overwritten due to continuous write operations.
[0057] One aspect of the present application provides another data processing method for a multi-core controller applied to an auxiliary core. The data processing method has the same framework logic as any of the above data processing methods, and the only difference is the execution subject. Figure 7 , Figure 7 This is a flow chart illustrating another data processing method for a multi-core controller according to an exemplary embodiment of the present application. The multi-core controller includes a primary core and a secondary core, the primary core includes a proxy module, and the data processing method is applied to the secondary core, including at least steps S710 to S730, as detailed below: S710: Initiate a read request to the main core, and detect whether a first return value representing a read result fed back by the proxy module is received within a second preset time period; wherein the read request represents a request for performing a data read operation on the storage module.
[0058] In order to ensure the timeliness of the relevant return value, this embodiment of the auxiliary core has an invalidation monitoring mechanism, setting a second preset time to monitor the invalidation of the first return value. In some embodiments, the auxiliary core will also monitor the invalidation of the second return value corresponding to the relevant write request, which will not be repeated here.
[0059] The second preset duration can also be a preset number of proxy cycles, just like the first preset duration. This application does not limit its specific duration, nor does it limit the size relationship between the first preset duration and the second preset duration. They can both be adaptively adjusted according to actual scenario requirements.
[0060] S720: If a first return value is received within a second preset time period, and the reading result of the first return value indicates a successful reading, a local operation is performed based on the received read value; wherein the read value is a value read by the proxy module from the storage module.
[0061] If the first return value is a value indicating a successful read, the proxy module returns the first return value to the slave core and also returns the read value read from the storage module to the slave core.
[0062] S730: If the first return value is received within the second preset time period, and the reading result of the first return value indicates a reading failure, performing a local operation based on the local preset value.
[0063] If the first return value is a reading result indicating a reading failure, the pointer proxy module does not read the relevant data from the storage module. The proxy module only returns the first return value indicating a reading failure to the auxiliary core, without a reading value. The auxiliary core then performs local operations based on local preset values, thereby effectively ensuring the operation of the basic functions of the auxiliary core.
[0064] This embodiment uses a proxy module in the main core to read data from the storage module, thereby preventing multiple auxiliary cores from accessing the storage module simultaneously and causing a decrease in storage module stability. The proxy module can return a first return value representing the read result to the corresponding auxiliary core, so that the auxiliary core can determine whether to perform a local operation based on a local preset value based on the first return value. This embodiment introduces the local preset value as a fallback execution value to avoid the loss of basic auxiliary core functions due to read failures, thereby effectively ensuring the operation of the auxiliary core's basic functions.
[0065] Another aspect of the present application provides a multi-core controller, such as Figure 2 As shown, the multi-core controller includes a main core and an auxiliary core, and the main core includes an agent module.
[0066] The auxiliary core initiates a read request to the main core. In response to the read request, the main core calls the proxy module to perform a read operation on the storage module. The proxy module returns a first return value representing the read result to the auxiliary core. Based on the first return value, the auxiliary core determines whether to perform a local operation based on a local preset value.
[0067] In another exemplary embodiment, the proxy module is configured to determine a response order for each request based on the request time of each request. Specifically, the proxy module can prioritize related read requests and / or related write requests to avoid read / write conflicts caused by responding to multiple requests simultaneously, thereby preventing impacts on the stability of the main core and storage module. In certain embodiments, the proxy module includes a request queue for prioritizing responses to each request. Each received request is sequentially placed into the request queue based on its receipt time. The request queue then outputs related requests for response in a first-in, first-out manner, thereby achieving prioritized responses to each request.
[0068] The proxy module is further configured to record the number of write requests received from the same source within a first preset time period. If the number of write requests received from the same source within the first preset time period exceeds a preset number, the write function of the source (the source slave core or an application in the slave core) is restricted.
[0069] In another exemplary embodiment, Figure 5 As shown, the multi-core controller also includes a recording module for completely recording the response status of read requests and write requests, so as to facilitate tracing relevant data during problem analysis and improve data traceability.
