The Research and Implementation Of Universal Simulation In Embedded CPU Instruction System

嵌入式系统的软件仿真可以使开发者对嵌入式系统架构的正确性及性能进行验证，从而大大降低开发成本和时间，是保证和提高嵌入式开发软件可靠性的重要手段。但目前市场上大多数的嵌入式系统软件仿真平台中对CPU指令模块的仿真都是从编译后的机器语言入手，这样就造成对嵌入式处理器生产厂家的编译器的依赖，阻碍了软件仿真的发展。为此本文提出了基于源代码分析的指令仿真技术，即对嵌入式应用软件代码的仿真采取直接从汇编源代码仿真执行入手，而不需要通过具体的机器语言，并提出用基于编译原理的“三个分析”方法来实现对源代码的功能仿真。 在目前现有的嵌入式系统软件仿真工具中，还未出现针对凌阳SPCE061A单片机的软件仿真器。...Software simulation is used to test the validity and performance of the structure in embedded system, which greatly reduces the cost and time of development. In addition, it's an important method to guarantee and improve the reliability of embedded developing software. But at present, most of the software simulation platform for simulating CPU module in embedded system is based on the binary code ...学位：工学硕士院系专业：信息科学与技术学院通信工程系_通信与信息系统学号：2332006115260
