The Simulation Of The Single Chip Microcomputer System

Principle and Interface-technology of Single chip microcomputer is a main course in engineering college, and the problem that the hardware simulators of single chip microcomputer go out of work often happens. Therefore, the simulation software was developed in this paper to avoid it. The hardware simulators of single chip microcomputer and the assemble language of single chip microcomputer will be replaced by the simulation software of single chip microcomputer, which is based on PC platform, was programmed with VB6.0, and is able to simulate the software and hardware of single chip microcomputer.The task includes two parts. Firstly, the demands of the peripheral equipment of the single chip microcomputer system should be inputted into PC through conversation between people and PC, and the peripheral circuits should be created automatically according to it. Secondly, the running states of the system (peripheral circuits and inputted-assemble-language) according to the inputted-assemble-language instructions needed to be displayed. The first part was mainly introduced in this paper.The principle of discrete-system simulation was firstly introduced, and the method of the simulating procedure was discussed in details, which were the foundations of task.Secondly, the principle of OOP-expert-systems, the gaining of knowledge, the building of knowledge-base and the reasoning method were discussed detailedly. The expert-system of fault-diagnosis was built to recognize the false instructions inputted by the users.The programming method and the realization of the whole system were introduced. The software was debugged and finished. The assuming plan of how to simulate the peripheral interruptions was introduced at the last.
