Detailed Description
Some embodiments of the invention are described below with reference to the accompanying drawings in conjunction with a single-chip microcomputer. It should be understood by those skilled in the art that these embodiments are only for explaining the technical principle of the present invention, and are not intended to limit the scope of the present invention. The solution according to the invention can obviously also be applied to control devices having other forms, without departing from the basic principle of the invention.
In the description of the present application, a "processor" may include hardware, software, or a combination of both. The processor may be a central processing unit, a microprocessor, or any other suitable processor. The processor has data and/or signal processing functionality. The processor may be implemented in software, hardware, or a combination thereof. Non-transitory computer readable storage media include any suitable medium that can store program code, such as magnetic disks, hard disks, optical disks, flash memory, read-only memory, random-access memory, and the like. The term "a and/or B" denotes all possible combinations of a and B, such as a alone, B alone or a and B. The term "at least one A or B" or "at least one of A and B" means similar to "A and/or B" and may include only A, only B, or both A and B. The singular forms "a", "an" and "the" may include the plural forms as well. A User application (User application) refers to main computer code that is stored in a User area of the ROM memory and used for implementing functions of the control device, and a Boot application (Bootloader) refers to a program that is stored in the Boot area of the ROM memory and used for controlling the User application in the User area, such as erasing and programming the computer code in the User area (for example, erasing an original User application and then programming a new User application when upgrading the User application).
In the prior art, a Boot area and a User area are arranged in a ROM memory of a control device such as a single chip microcomputer, the Boot area is configured to store a Boot application program capable of performing upgrading work on the User area, and the User area is configured to store the User application program. After the single chip microcomputer is powered on and started or reset, a Boot application program firstly initializes the single chip microcomputer to configure the operating environment required by all application programs stored in a ROM (read only memory), and the operating environment configuration comprises but is not limited to: and respectively allocating storage spaces of the RAM memory for Boot applications, User applications and other applications, so that each application can store operation data generated and/or used by operation in the corresponding RAM storage space during operation. Subsequently, the Boot application will detect whether a User application upgrade instruction is received. If the Boot application program detects a User application program upgrading instruction, the Boot application program can completely erase the User application program in the User area and rewrite a new User application program, and after the erasing and the rewriting are completed, the Boot application program jumps to the User area, and then the new User application program is operated in the User area. If the Boot application program does not detect a User application program upgrading instruction, the single chip microcomputer is initialized and then directly jumps to a User area, and then the User application program is operated in the User area. Further, when the User application program is operated, if the User application program detects a User application program upgrading instruction, the User application program interrupts operation, and the single chip microcomputer immediately jumps to the Boot area after the User application program is interrupted, so that the Boot application program is operated again in the Boot area, and at this time, the operation process of the Boot application program is the same as that of the Boot application program, and is not described herein again.
As can be seen from the above, all the application programs (such as Boot application program, User application program, other application programs, etc.) stored in the ROM memory of the single chip microcomputer share one start program, and when the single chip microcomputer is started or reset, the start program configures the software and hardware environment of the single chip microcomputer according to the operation requirements of all the application programs. Meanwhile, data used when the Boot application program erases and programs the User application program can be stored in the RAM through a Boot program, when the User application program needs to be erased and programmed, the Boot application program can call the data to erase and program the User application program, the data are still stored in the RAM to continuously occupy the storage space of the RAM after the erasing and programming work is finished, and when the storage space of the RAM is small or the storage space occupied by the Boot application program is large, the storage space of the RAM may be insufficient, so that the normal operation of all the application programs cannot be guaranteed. For example, in a certain single chip microcomputer provided by the rassa technology, the storage space of the RAM memory is 2K, the storage space required to be occupied by the database of the Boot application program is 1300B, and the Boot application program itself also occupies at least several hundred bytes of storage space, when the single chip microcomputer is started, the Boot program allocates most of the storage space of the RAM memory to the Boot application program for use, and other application programs almost have no available storage space.
In the embodiment of the invention, each application program (such as a User application program and a Boot application program) is configured with an independent startup program, when a certain application program needs to be run, the startup program of the application program initializes the single chip microcomputer to clear all storage spaces of the RAM memory and completely allocate all the storage spaces after clearing to the application program for use, namely, the startup program can not only configure the hardware environment and the software environment of the control device for the running of the application program, but also provide sufficient running data (running data generated/used during the running of the application program) storage spaces for the running of the application program by clearing all the storage spaces of the RAM memory, thereby ensuring the normal running of the application program.
Referring first to fig. 1, fig. 1 is a flowchart illustrating main steps of a program operating method of a control device such as a single chip microcomputer according to an embodiment of the present invention. In this embodiment, the control device includes a ROM memory that stores a plurality of application programs and a boot program corresponding to each application program, and a RAM memory that stores operation data generated/used when the application programs in the ROM memory are operated. The application program stored in the ROM refers to computer program code written in a computer coding language for the purpose of realizing a certain application of the control apparatus, and for example, the application program may be a system application program, a driver application program, or the like. The starting procedure of the application program refers to preprocessing the hardware configuration and the software configuration of the control device before the application program is run, so that the hardware environment and the software environment of the control device both meet the running requirements of the application program. For example, a stack pointer and a program counter pointer of the single chip microcomputer are initialized, sizes of the stack and the heap are set, and an external Static Random-Access Memory (SRAM) is configured as a data Memory, and the like. In addition, in this embodiment, the start-up program may also clear all the storage spaces of the RAM memory and allocate all the storage spaces after the clearing to the corresponding application program for use, so that the application program may utilize all the storage spaces of the RAM memory to store the operation data required for operation and the operation data generated by operation during operation. As shown in fig. 1, the program running method of the control device in the present embodiment mainly includes the following steps:
step S101: when an application program is to be run, the startup program corresponding to the application program performs initialization processing on the control device to clear all the storage space of the RAM memory and allocate all the storage space to the application program for use.
In an embodiment, the ROM memory may include a Boot area and a User area, the Boot area may be configured to store a Boot application program capable of performing an upgrade operation on the User area, the User area may be configured to store a User application program and a corresponding Boot program, and the Boot program of the Boot application program may be stored in other storage areas of the ROM memory. The following describes a storage space allocation method of the RAM memory in this embodiment with reference to fig. 2 (that is, when an application is to be run, a startup program corresponding to the application performs initialization processing on the control device to clear all storage spaces of the RAM memory and allocate all storage spaces to the application for use). Referring to fig. 2, fig. 2 is a flowchart illustrating the main steps of a method for allocating a storage space of a RAM memory of a control device, such as a single chip microcomputer, according to an embodiment of the present invention. In this embodiment, the method for allocating the storage space of the RAM memory mainly includes the following steps:
step S1011: after the control device is started or reset, the control device is initialized through a Boot program corresponding to the Boot application program so as to clear all storage spaces of the RAM memory and allocate all the storage spaces to the Boot application program for use.
The control device is started, namely the control device is powered on again in a power-off state, and the control device is reset, namely the control device is operated again according to a reset signal in a power-on state. For example, the reset of the single chip microcomputer may be that a reset signal is input at a reset end of the single chip microcomputer, and the single chip microcomputer operates again after detecting the reset signal.
Further, in an embodiment, the number of Boot areas may be multiple, and each Boot area stores a type of Boot application program, in this case, step S1011 may be: after the control device is started or reset, selecting a Boot application program with the highest operation priority according to the operation priority of a preset Boot application program; and initializing the control device by a Boot program for running the Boot application program with the highest priority so as to clear all storage spaces of the RAM and allocate all storage spaces to the Boot application program with the highest running priority for use.
It is to be noted that, although the embodiment of the present invention selects and runs the Boot application according to the running priority of the Boot application, it will be understood by those skilled in the art that the scope of the present invention is obviously not limited to this specific implementation. Without departing from the principle of the present invention, a person skilled in the art may select a Boot application from multiple Boot applications to run by other methods, and such modifications or replacements will fall within the protection scope of the present invention.
Step S1012: and acquiring a program jump flag bit of the current ROM.
The program jump flag bit contains address information of the storage area of the application program in the ROM, and the corresponding storage area can be jumped to according to the address information, so that the corresponding application program can be operated in the storage area. For example, when the program jump flag is a Boot jump flag, the program jump flag includes an address of the Boot area, and the program can jump to the Boot area according to the address. Furthermore, after the program jump flag bit is set, the program jump flag bit is stored in a public storage area, and each application program can access the program jump flag bit.
Step S1013: and judging whether to run the User application program or not according to the program jump flag bit and the address of the User area.
Specifically, if the address information in the program jump flag bit is the same as the address of the User area, it is determined that the User application needs to be run, and then the process may proceed to step S1014; if the address information in the program jump flag is different from the address of the User area, it is determined that the User application does not need to be run, and then the process may proceed to step S1015.
Step S1014: jumping to the User area, and initializing the control device again in the User area through a starting program corresponding to the User application program so as to clear all storage spaces of the RAM memory and allocate all storage spaces to the User application program for use.
Step S1015: no memory space of the RAM memory is allocated to the User application.
In the embodiment, both the Boot application program and the User application program are configured with separate Boot programs, when the Boot application program or the User application program needs to be operated, the single chip microcomputer is initialized through the Boot program corresponding to the Boot application program or the User application program to clear all storage spaces of the RAM memory and all the cleared storage spaces are allocated to the Boot application program or the User application program for use, and sufficient storage spaces of operation data (operation data generated/used during the operation of the application program) are provided for the operation of the Boot application program or the User application program, so that the normal operation of the Boot application program or the User application program is ensured.
Step S102: and running the application program.
In one embodiment, the ROM memory may further store an interrupt vector table corresponding to each application program, the application programs may include a main program and an interrupt handler, and running the application program may include the steps of: the method comprises the steps of firstly running a main program of a current application program and setting an interrupt flag bit, acquiring an address of an interrupt handling program of the current application program from an interrupt vector table of the current application program according to the interrupt flag bit if an interrupt signal is detected in the running process of the main program, then jumping to the corresponding interrupt handling program according to the address, and then running the interrupt handling program.
The main program refers to a main function of the computer program, the interrupt processing program refers to an interrupt function of the computer program, the interrupt vector table refers to a storage space for storing interrupt vectors, the interrupt vectors refer to entry addresses of the interrupt processing program or addresses of a storage area for storing the interrupt processing program, the addresses corresponding to the interrupt processing program can be obtained by inquiring the interrupt vector table, and the interrupt processing program can be jumped to according to the addresses.
In one embodiment, the ROM memory may further store a ROM storage space allocation program corresponding to each application program, and before executing step S101, a ROM storage area may be further allocated to each application program by the ROM storage space allocation program corresponding to each application program, so as to store each application program. In the prior art, all application programs stored in a ROM memory of a control device such as a singlechip share one interrupt vector table and a ROM storage space allocation program, and in the embodiment of the invention, the interrupt vector table and the ROM storage space allocation program are respectively set for each application program, so that each application program is completely independent from each other and does not influence each other, and the normal operation of the application programs is further ensured.
With continuing reference to fig. 2, in the embodiment shown in fig. 2, when the determination result of step S1013 is that the User application needs to be run, step S1016 is further included after step S1014 is executed, where step S1016 specifically is: the User application is run directly in the User area. When the determination result in step S1013 is that the User application does not need to be run, step S1017 is further included after step S1015 is executed, where step S1017 specifically is: and skipping to the Boot area according to the address of the Boot area and running a Boot application program in the Boot area. Further, when the number of Boot areas may be multiple and each Boot area stores a type of Boot application, step S1017 may also be: and skipping to a corresponding Boot area according to the address of the Boot area of the Boot application program with the highest running priority, and running the Boot application program with the highest running priority in the Boot area.
Further, when the User application program is operated, whether a User application program updating instruction is received or not can be detected in real time through the User application program, and whether the Boot application program is operated or not is judged according to a detection result. The User application update command is a command for performing a program update (i.e., erasing an original User application and rewriting a new User application, such as upgrading the User application) on a User application in a User area in the ROM memory.
Specifically, when a User application program updating instruction is detected, it indicates that program updating needs to be performed on a User application program in a ROM memory, at this time, address information in a program jump flag is set as an address of a Boot area and a reset interrupt program is run, after the reset interrupt program is run, all storage spaces of a RAM memory can be allocated to the Boot application program by executing step S1011, and the Boot application program is run by executing steps S1012 to S1017, thereby completing program updating of the User application program. And when the User application program updating instruction is not detected, continuing to run the User application program and detecting whether the User application program updating instruction is received or not in real time through the User application program.
Furthermore, after the Boot application program is completely run, the program jump flag bit can be reset through the Boot application program, so that the User application program can be run after the control device is started or reset.
Specifically, after the Boot application program is completely run, the program jump flag bit is reset according to the address of the User area, so that the User application program can jump to the User area according to the program jump flag bit and run in the User area after the control device is started or reset. Such as the execution of the User application by performing steps S1011 to S1016.
