基于ARM7的嵌入式系统虚拟实验平台的设计

The design of a virtual experimental platform of embedded system based on ARM7

针对目前嵌入式系统传统实验教学中实验设备少、实验模式枯燥、时空受局限等问题,采用Proteus和Keil开发工具,通过虚拟仿真技术,设计了一套基于ARM7内核的嵌入式系统虚拟实验平台。平台分基础型知识和综合型知识2个层次,并以外部中断实验为例,详细介绍了平台的设计过程,包括实验要求、硬件设计、软件设计和联合调试。最后采用模糊综合评价理论对该实验平台的教学效果进行了分析,实践表明,学生对该平台教学的总体评价等级为优秀。评价结果验证了该平台的实用性。

Through the virtual simulation technology , ？a virtual experimental platform of embedded system based on the ARM7 was designed with the Proteus and Keil tools to resolve the problems of short of experimental equipments, boring experimental model and limited space and time. The platform include the basic knowledge platform and the comprehensive knowledge platform. The design process of the platform are introduced in detail through the external interrupt experiment example, including the experimental requirements, hardware design, software design and joint debugging. Finally the teaching effect of the experimental platform is analyzed by using fuzzy comprehensive evaluation theory, and the practice shows that the teaching evaluation of the platform from students is good. The evaluation results proved the practicability of the platform.
