AI Technical Summary
In modular systems, traditional read/write methods result in long response times for slave modules, especially for low-speed communication modules such as I2C bus and UART serial communication modules. Furthermore, existing technologies lack effective methods to map out-of-order responses to corresponding read/write commands.
When a response command is received from a slave module, the system searches for the response number in a preset identifier table based on the response command's own identifier, and then determines the target row in a dynamic additional information table based on the response number. This ensures that each response command is matched with the previous request command, guaranteeing the sequential nature of the responses.
This ensures that each communication response is processed sequentially, reducing the need for data storage resources and improving communication efficiency.

Abstract
Description
Technical Field
[0001] This invention relates to the field of communication technology, and in particular to a data processing method, apparatus, storage medium, and terminal. Background Technology
[0002] In today's modular system design, the master unit often needs to read and write to each slave module. The traditional read and write method involves sending a read or write command and waiting for a read data response or a write response before executing the next read or write command. However, both read and write responses take a certain amount of time to complete, especially for slow-responding slave units such as I2C bus communication modules and UART serial communication modules, where the waiting time is particularly long.
[0003] Lead-ahead transmission solves the problem of long waiting times by allowing the host to send subsequent read / write commands before receiving a previous response. Each read / write command has an ID, and multiple commands can be sent with the same ID, but responses to the same ID must be sent in the order they were sent. This results in numerous read / write commands being sent sequentially to various slave devices, which may not respond in order; faster slaves may respond first, while slower ones may respond later, leading to out-of-order responses. Therefore, a method is needed to associate each response with previously sent commands, facilitating the retrieval and processing of this information upon response arrival. Currently, no such data processing method exists. Summary of the Invention

[0050] This application provides a data processing method, apparatus, storage medium, and terminal to solve the problems existing in the aforementioned related technologies. In the technical solution provided by this application, because the additional information of the target row can be determined in a dynamic additional information table by determining the response number and combining it with the self-identifier of the response command, each response command is mapped to the previously sent request command, ensuring that each communication response is performed sequentially, while reducing data storage resources. The following is a detailed description using exemplary embodiments.
[0051] The following will be combined with the appendix Figure 1 - Appendix Figure 2 This application provides a detailed description of the data processing method provided in its embodiments. This method can be implemented using a computer program and can run on a data processing device based on the von Neumann architecture. The computer program can be integrated into an application or run as a standalone utility application.
[0052] Please see Figure 1 This is a flowchart illustrating a data processing method provided in an embodiment of this application. Figure 1 As shown, the method in this application embodiment may include the following steps:
[0053] S101, when a response command is received from the slave module, the response number is searched in the preset identifier table according to the identifier of the response command itself;
[0054] In this embodiment, before receiving the response instruction from the slave module, a data read / write instruction sending stage is also included. First, when a data read / write instruction is detected, the data read / write parameters of the instruction are obtained, additional information is acquired, and then the request number and storage row number corresponding to the instruction are determined. Then, the storage row is determined in the dynamic additional information table based on the storage row number. Next, the identifier of the instruction, the request number, and the additional information are saved to the storage row. Finally, the data read / write instruction is sent to the slave module.
[0055] Specifically, when determining the request number and storage row number corresponding to the data read / write instruction, the system first searches for the request number corresponding to the self-identifier of the data read / write instruction in the preset identifier table, then reads a piece of data from the preset row identifier table, and determines the storage row number corresponding to the data read / write instruction based on the read data.
[0056] Furthermore, the storage row identifier of the storage row can be set to 1, and the request number in the preset identifier table can be automatically incremented by 1.
[0057] In one possible implementation, when a data read / write instruction is received, the corresponding request number (req_num) is first found from the preset identifier table num_table based on the instruction's own ID. At the same time, a piece of data is read from the preset row identifier table entry_num_fifo to determine which row in the dynamic additional information table info_table the data read / write instruction should reside in. Then, the instruction's own ID, request number, and additional information are filled into that row of info_table, and the storage row identifier vld of that row is set to 1, i.e., valid. Finally, the request number req_num in the preset identifier table num_table is incremented by 1.
[0058] In this embodiment, upon receiving a response command from the slave module, the response number can be searched in a preset identifier table based on the response command's own identifier. For example, the corresponding response number rsp_num can be found in the preset identifier table num_table based on the response command's own ID.
[0059] S102, determine the target row in the dynamic additional information table based on the response instruction's own identifier and response number;
[0060] In this embodiment of the application, when determining the target row in the dynamic additional information table based on the self-identifier and response number of the response instruction, it is first determined whether there is a target identifier and request number in the dynamic additional information table that are consistent with the self-identifier and response number of the response instruction; if so, the row containing the target identifier and request number that are consistent with the self-identifier and response number of the response instruction is determined as the target row.
[0061] Furthermore, the row number of the target row is cleared in the dynamic additional information table, and the row number of the target row is rewritten back into the preset row identifier table.
[0062] For example, the corresponding command is found in the dynamic additional information table info_table using the response command's own identifier and response number rsp_num. This line must be unique. After finding it, the additional information info in that line is retrieved and used as additional information for the response command. The line number of this line is written to the preset line identifier table entry_num_fifo for use by subsequent commands. At the same time, the response can perform further processing as needed after retrieving the additional information.
[0063] S103, determine the additional information in the target line as additional information for the response instruction.
[0064] In this embodiment of the application, after the target line is determined, the additional information info can be extracted and determined as the additional information of the response instruction.
[0065] For example Figure 2 As shown, Figure 2 This is a flowchart illustrating a data processing procedure provided in this application. First, a data read / write command is detected, such as "read or write cmd with info, and id = 1". At this time, the data read / write command's own identifier is 1, and the additional information is "info". Then, based on its own identifier 1, the corresponding request number "req_num" is searched in the preset identifier table "num_table". Next, a row number is read from the preset row identifier table "entry_num_fifo", for example, 2. At this time, the data read / write command's own identifier, request number, and additional information are stored in the second row of the dynamic additional information table, starting from row number 0. The "req_num" in the preset identifier table is incremented by 1, so that one request number always corresponds to one response number. The data read / write command is then sent to the slave module. After processing, the slave module can respond with a response command to the master. When the master receives the response command from the slave module, it can look up the response number rsp_num in the preset identifier table num_table based on the response command's own identifier ID. Then, based on the response number rsp_num and its own identifier ID, it matches the corresponding row number in the dynamic additional information table info_table and extracts the additional information info from that row number to obtain the additional information of the response command. This process ensures that a request and a response always correspond one-to-one, avoiding out-of-order responses.
[0066] In this embodiment, when the data processing device receives a response command from the slave module, it first looks up the response number in a preset identifier table based on the response command's own identifier. Then, it determines the target row in a dynamic additional information table based on the response command's own identifier and the response number. Finally, it determines the additional information in the target row as the additional information of the response command. Because this application determines the additional information of the target row in the dynamic additional information table by determining the response number and combining it with the response command's own identifier, it ensures that each response command corresponds to the previously sent request command, guaranteeing that each communication response is performed sequentially, while simultaneously reducing data storage resources.

The apparatus 1 includes a response number lookup module 10, a target row determination module 20, and an additional information determination module 30.
[0069] The response number lookup module 10 is used to look up the response number in a preset identifier table based on the identifier of the response instruction itself when a response instruction is received from the slave module.
[0070] The target line determination module 20 is used to determine the target line in the dynamic additional information table based on the self-identifier and response number of the response instruction;

[0072] Optional, for example Figure 4 As shown, device 1 also includes:
[0073] The additional information generation module 40 is used to obtain the data read / write parameters of the data read / write command and obtain additional information when a data read / write command is detected.
[0074] The parameter determination module 50 is used to determine the request number and storage row number corresponding to the data read / write instruction;
[0075] The storage row determination module 60 is used to determine the storage row in the dynamic additional information table based on the storage row number;
[0076] The parameter storage module 70 is used to save the data read / write instruction's own identifier, request number, and additional information to the storage line;
[0077] The instruction sending module 80 is used to send data read / write instructions to the slave module.
