The single-chip simulator refers to a set of dedicated hardware devices specially designed and manufactured for the purpose of debugging the single-chip software.
The single-chip microcomputer is completely the same as the PC in the architecture, and it also includes the central processing unit, input and output interfaces, memory and other basic units, so it is similar to the software structure of the PC and other equipment. Therefore, in the process of software development, the single-chip microcomputer also needs to debug the software, observe the intermediate results, and eliminate the problems in the software. However, due to the application of the single-chip microcomputer, it does not have a standard input and output device, and limited by storage space, it is difficult to accommodate special software for debugging. Therefore, to debug the software of the single-chip microcomputer, a single-chip simulator must be used. The single-chip simulator has basic input and output devices, and has software that supports program debugging, so that single-chip developers can input and modify programs through the single-chip simulator, observe the program running results and intermediate values, and at the same time check and observe the hardware supporting the single-chip , Can greatly improve the programming efficiency and effect of the microcontroller.
The earliest single-chip simulator is a set of independent devices, with a dedicated keyboard and display, used to input programs and display the results of the operation; with the popularity of PCs, most of the new generation of simulators use PCs as standard input The output device, and the simulator itself becomes the interface between the microcomputer and the target system. The simulation method has also developed from the initial machine code to assembly language and C language simulation. The simulation environment is also very similar to the high-level language programming and debugging environment on the PC. Up.
The emulator generally has an emulation head, which is used to replace the single-chip microcomputer in the target system, that is, the plug is used to imitate the single-chip microcomputer, which is also the origin of the name of the single-chip simulator.
At present, with the miniaturization and placement of single-chip microcomputers and the wide application of single-chip microcomputers with ISP and IAP functions, the application range of traditional single-chip simulators has also been reduced. The application of software single-chip simulator (ie single-chip simulation program) is gradually becoming more widely used. The single-chip simulation program is a special program that runs on a personal computer, which can simulate the hardware environment of the single-chip computer to a certain extent, and run the single-chip target program in this environment , And can debug the target program, break points, observe variables and other operations, which can greatly improve the debugging efficiency of the single-chip system. Pure software single-chip microcomputer simulators are often integrated and released together with hardware design programs, so that developers can simultaneously develop single-chip hardware and software.
