Research And Realization Of Simulation Platform Of Micro-Chips In Embedded Systems

Software simulation of embedded systems is an important method to support software testing.By using System Simulation methodology to simulate both the software and hardware of embedded micro-chips,the simulation platform can be used to test the embedded programmes and to assist the design of chips.Integrated into design tools or testing tools of micro-chips,simulation platform plays essential roles to ensure the stable and efficient performances of embedded programmes and embedded micro-chips themselves.The research on this field can be of great value both theoretically and practically.This thesis is a spirited and useful attempt based on the object above.Current embedded system simulation softwares mostly are capable of imitating a particular kind of micro-chip.An universal simulation platform which can imitate various micro-chips is introduced and implementd in this thesis.The simulation platform in the thesis is able to imitate two different types of micro-chips.The thesis mainly focuses on the simulatons of various interior hardwares in embedded micro-chips.By using MFC mode of programing in Visual C++,the universal simulation platform imitates the hardware parts of two micro-chips as follows:CPU core,memory,input/output ports, interruption system,A/D converter,D/A converter and serial access ports. Those hardware parts are common in embedded micro-chips.In order to achieve the expansibility,compatibility and universalism of the simulation platform,in the process of implementation,Design Patterns Methodology was referenced,and so was Object-oriented Program Methodology.The implementation test of the simulation platform shows that every part of the simulation platform can integrally imitate the mechanisms of real micro-chips,while working effectively together.The design and implementation of the this simulation platform can be widely used to imitate other embedded micro-chips,therefore,the thesis is expected to facilitate the future foundation of a comprehensive and universal software auto-testing system.
