[0015] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0016] In an embodiment of the present application, the inventor proposes a driver code optimization method, device, and electronic device, which generates a template code based on the function names, register addresses, and register values ​​corresponding to all functions after traversing and calling all functions in the driver code and obtaining the register addresses and register values ​​corresponding to all functions. Through the above method, it is possible to traverse and call all functions in the driver code, obtain the register addresses and register values ​​corresponding to all functions, and then generate a template code based on the function names, register addresses, and register values ​​corresponding to all functions, thereby simplifying the lengthy driver code into a template code containing register addresses and register values, that is, in the subsequent development and use process, the driver code can be replaced by the template code, so that while reducing the storage space occupied by the code, the difficulty of the driver code being reverse cracked can be increased, thereby improving the security of the driver code.

[0017] See also Figure 1 , an embodiment of the present application provides a driver code optimization method, the method comprising:

[0018] S110: Traverse and call all functions in the driver code, and obtain the register addresses and register values ​​corresponding to all functions.

[0019] Among them, the electronic device may be provided with Figure 2 The peripheral simulation software 11 shown. The peripheral simulation software 11 may include a virtual communication node 111, a virtual register module 113, a control configuration module 115, a timing recording module 117, and a hardware connection module 119. The hardware peripherals may be sensors, actuators, EMMC, DDR, Norflash, etc. The electronic device may be a terminal device, such as a computer, a tablet, a server, etc., and the electronic device may also be a device used for code transplantation or development in a vehicle.

[0020] The virtual communication node 111 can be used to transmit driver code and configuration information. The driver code can refer to the code developed by the SDK (Software Development Kit) provided by the hardware peripheral chip manufacturer. The driver code and the hardware peripheral can be a one-to-one correspondence, that is, a driver code developed by the manufacturer is only applicable to one hardware peripheral. The configuration information can refer to the working mode, data transmission efficiency, data read and write interface, etc. of the peripheral simulation software 11 in the electronic device. The working mode can include a transparent transmission mode, a conversion mode, a data mode, a simulation mode, etc. The virtual communication node 111 can include a first virtual communication node and a second virtual communication node, wherein the first virtual communication node can be used to transmit configuration information, and the second virtual communication node can be used to transmit the driver code.

[0021] The virtual register module 113 may include one or more virtual registers corresponding to hardware peripherals. The control configuration module 115 may be used to transmit data and control the peripheral simulation software 11 to work. The timing recording module 117 may be used to record the timing relationship of all functions in the driver code, i.e., the execution order. The hardware connection module may be used to complete the data transmission between the control peripheral simulation software 11 and the hardware peripherals.

[0022] As a method, the control configuration module 115 can traverse and call all functions in the driver code; obtain the register addresses and register values ​​corresponding to all functions through the virtual registers corresponding to the first hardware peripheral, and the driver code is developed based on the first hardware peripheral.

[0023] Among them, when the control configuration module 115 traverses and calls all functions in the driver code, it will involve access to the virtual registers corresponding to the first hardware peripheral, modifying the data content, etc. Therefore, when traversing and calling all functions in the driver code, the virtual registers corresponding to the first hardware peripheral can be used to obtain the register addresses and register values ​​corresponding to all functions, and the execution order of all functions can be recorded through the timing recording module 117.

[0024] S120: Generate template code based on the function names, register addresses and register values ​​corresponding to all functions.

[0025] As a method, when the working mode of the electronic device is the transparent transmission mode, the control configuration module 115 can write the register values ​​corresponding to all functions into the register corresponding to the first hardware peripheral based on the register addresses corresponding to all functions; receive the communication process data corresponding to all functions returned by the first hardware peripheral; and generate template code based on the function names, register addresses, register values ​​and communication process data corresponding to all functions.

[0026] The transparent transmission mode may refer to a mode in which the acquired data (register address and register value) is directly transmitted to the hardware peripheral without any modification. The communication process data may refer to the data generated by the first hardware peripheral in the process of writing the register values ​​corresponding to all functions into the register corresponding to the first hardware peripheral.

[0027] In an embodiment of the present application, after the work content of the transparent transmission mode is executed, there are two ways to generate template code based on the function names, register addresses, register values ​​and communication process data corresponding to all functions.

[0028] As an implementation method, when the working mode of the electronic device is switched from the transparent transmission mode to the code generation mode, the control configuration module 115 can obtain the function names and read-write interfaces corresponding to all functions; based on the function names, read-write interfaces, register addresses, register values, and communication process data corresponding to all functions, generate template code.

[0029] Among them, the code generation mode can be used to convert the driver code into a template code. After entering the code generation mode, the control configuration module 115 can read the function function list (ie, function name) and read-write interface corresponding to the driver code, and generate the template code in combination with the recorded communication data.

[0030] As another implementation method, when the working mode of the electronic device is switched from the transparent transmission mode to the data mode, the control configuration module 115 can send the register addresses, register values ​​and communication process data corresponding to all functions to the target device, so that the target device generates a template code based on the function names, register addresses, register values ​​and communication process data corresponding to all functions.

[0031] The target device may refer to the electronic device itself or another electronic device connected to the electronic device. The data mode may be used to transfer data in the peripheral simulation software 10 to the target device, or to import the acquired register values ​​and register addresses from the target device to the peripheral simulation software 10.

[0032] Optionally, after the target device receives the function names, register addresses, register values ​​and communication process data corresponding to all functions, the acquired function names, register addresses, register values ​​and communication process data corresponding to all functions can be displayed to the R&D personnel through the screen, so that the R&D personnel can make manual modifications according to the needs of the R&D tasks (such as adjusting the function execution order, deleting or adding certain functions, etc.), and then use the modified results as template codes.

[0033] In the embodiment of the present application, by combining the transparent transmission mode with the code generation mode to generate the template code, the automatic generation of the template code can be realized, which is faster and more convenient; by combining the transparent transmission mode with the data mode to generate the template code, the template code can be generated in a personalized manner, which improves the flexibility of the generated template code. The above two methods of generating template code can replace the driver code with the template code, thereby reducing the redundancy of the code and improving the uninterpretability of the code. That is to say, in the application scenario of driver code optimization, any of the above two methods can be selected according to one's own needs.

[0034] Optionally, before generating the template code based on the function names, register addresses and register values ​​corresponding to all functions, the control configuration module may obtain configuration information such as the working mode of the electronic device as shown in Table 1 from the first virtual communication node.

[0037]

[0038] The present embodiment provides a driver code optimization method, which generates template code based on the function names, register addresses and register values ​​corresponding to all functions after traversing and calling all functions in the driver code and obtaining the register addresses and register values ​​corresponding to all functions. Through the above method, it is possible to traverse and call all functions in the driver code, obtain the register addresses and register values ​​corresponding to all functions, and then generate template code based on the function names, register addresses and register values ​​corresponding to all functions, thereby simplifying the lengthy driver code into a template code containing register addresses and register values, that is, in the subsequent development and use process, the driver code can be replaced by the template code, so that while reducing the storage space occupied by the code, the difficulty of the driver code being reverse cracked can be increased, thereby improving the security of the driver code.

[0039] See also Figure 3 , an embodiment of the present application provides a driver code optimization method, the method comprising:

[0040] S210: In response to receiving a virtual register address that the driver code needs to access from the second virtual communication node, sending a write request to the virtual register address.

[0041] The virtual register address may be a virtual register address of the first hardware peripheral corresponding to the driver code in the virtual register module 113 .

[0042] As a method, the control configuration module 115 in the electronic device may send a write request to the virtual register address in response to receiving the virtual register address that the driving code needs to access from the second virtual communication node.

[0043] Optionally, when the peripheral simulation software 10 is started, a virtual communication node, such as a first virtual communication node and a second virtual communication node, can be virtualized first, so that when the driver code accesses the peripheral simulation software 10, the virtual register address that the driver code needs to access can be sent through the second virtual communication node first, so that the control configuration module 115 responds to receiving the virtual register address that the driver code needs to access from the second virtual communication node, and sends a write request to the virtual register address.

[0044] S220: If the feedback information received about the virtual register address indicates that writing is allowed, all functions in the driver code are written into the virtual register address.

[0045] As a method, if the control configuration module 115 receives feedback information of the virtual register address indicating that writing is allowed, all functions in the driver code are written to the virtual register address.

[0046] Optionally, when it is necessary to read data in the peripheral simulation software 10, the register address to be accessed may be sent through the second virtual communication node first, and wait for receiving data returned by the corresponding register address.

[0047] S230: Traverse and call all functions in the driver code, and obtain the register addresses and register values ​​corresponding to all functions.

[0048] S240: Generate template code based on the function names, register addresses and register values ​​corresponding to all functions.

[0049] S250: Based on the mapping relationship between the register address of the first hardware peripheral and the register address of the second hardware peripheral, convert the register addresses and register values ​​corresponding to all the functions into the register addresses and register values ​​in the second hardware peripheral.

[0050] As a method, when the working mode of the electronic device is the conversion mode, the control configuration module 115 can convert the register addresses and register values ​​corresponding to all functions into the register addresses and register values ​​in the second hardware peripheral based on the mapping relationship between the register addresses of the first hardware peripheral and the register addresses of the second hardware peripheral.

[0051] Among them, the first hardware peripheral and the second hardware peripheral can be peripheral chips of the same series, such as Realtek 9071, Realtek 9072, etc.; the first hardware peripheral and the second hardware peripheral can also be chips that comply with the same industry specifications, such as PHY chips. The industry stipulates that the values ​​of the first 32 registers are the same, so that the mapping relationship between the register address of the first hardware peripheral and the register address of the second hardware peripheral is known.

[0052] Among them, the first hardware peripheral and the second hardware peripheral can also be chips of different series and different industry specifications. In this case, you can first confirm whether the first driver code and the second driver code exist, wherein the first driver code is a code developed for the first hardware peripheral, and the second driver code is a code developed for the second hardware peripheral, and the first driver code and the second driver code play the same role; if they exist, you can simulate the first driver code and the second driver code and track the running data to obtain the mapping relationship between the register address of the first hardware peripheral and the register address of the second hardware peripheral.

[0053] Optionally, at this time, the electronic device may not be configured with the first hardware peripheral, but only with the second hardware peripheral.

[0054] S260: Generate a migration template code based on function names corresponding to all functions, register addresses and register values ​​in the second hardware peripheral, where the migration template code is used to run in the second hardware peripheral.

[0055] As a way, when the working mode of the electronic device is the conversion mode, the control configuration module 115 can generate a migration template code based on the function names corresponding to all functions, the register addresses and register values ​​in the second hardware peripheral.

[0056] Optionally, when the driver code is debugged for the first time or the first hardware peripheral is lacking, the R&D personnel can set the working mode of the electronic device to simulation mode, so that when the control configuration module 115 receives the configuration information of the simulation mode, it can simulate the first hardware peripheral and provide an interactive interface and virtual interactive data during simulation.

[0057] In the embodiment of the present application, the driver code debugging is completed through the simulation mode, which can solve the problem that the embedded software is heavily dependent on the hardware board, that is, hardware simulation is realized at a low cost, so that the debugging of the driver code does not need to rely on the hardware.

[0058] A driver code optimization method provided in this embodiment can traverse and call all functions in the driver code through the above method, and obtain the register addresses and register values ​​corresponding to all functions, and then generate template codes based on the function names, register addresses and register values ​​corresponding to all functions, so as to simplify the lengthy driver code into template codes containing register addresses and register values, that is, in the subsequent development and use process, the driver code can be replaced by the template code, so that while reducing the storage space occupied by the code, the difficulty of the driver code being reverse cracked can be increased, and the security of the driver code is improved. In addition, in this embodiment, based on the conversion mode, the driver code that is only applicable to the first hardware peripheral can be changed into a migration template code that can be applicable to the second hardware peripheral, so that the same driver code can be adapted to multiple hardware peripherals, so that the driver code can be used across platforms, and the transplantation difficulty of embedded software (such as driver code) can be reduced. In addition, in this embodiment, by setting multiple working modes of electronic devices, and based on one or more working mode combinations, the application of driver code optimization, code platformization, and code simulation in three scenarios can be completed, so that the driver code is optimized through the above three application scenarios, the driver code is reduced, the driver code transplantation degree is reduced, and the limitation of relying on hardware is overcome.

[0066] Optionally, the information acquisition unit 410 is specifically used to obtain the working mode of the electronic device from the first virtual communication node.

[0067] As a method, the code optimization unit 420 is specifically used to convert the register addresses and register values ​​corresponding to all the functions into the register addresses and register values ​​in the second hardware peripheral based on the mapping relationship between the register addresses of the first hardware peripheral and the register addresses of the second hardware peripheral; based on the function names corresponding to all the functions, the register addresses and register values ​​in the second hardware peripheral, generate a migration template code, and the migration template code is used to run in the second hardware peripheral.

[0068] As a method, the information acquisition unit 410 is specifically used to send a write request to the virtual register address that the driver code needs to access in response to receiving the virtual register address from the second virtual communication node; if the feedback information received from the virtual register address indicates that the write is agreed, all functions in the driver code are written to the virtual register address.
