基于SOPC的微机原理与接口技术实验教学改革研究

Research on Teaching Reform of Microcomputer Principle and Interface Technology Experiment Teaching Based on SOPC

微机原理与接口技术是一门实践性较强的高校计算机专业课程。针对目前该课程实验教学过程中的操作复杂及故障检测难的问题,提出一种基于SOPC技术的实验教学方法,以EP2C35F672C8芯片为平台设计出以8086 CPU为核心的软核片上系统,撤销原有的硬导线连接方法,改用Quartus II中的电路图来实现各种信号的软连接。实践表明,该方法充分发挥SOPC IP软核优势,有效降低了硬连线的故障排查时间和故障率,提高了学生的兴趣和实验效率。

Microcomputer principle and interface technology is a practical course for computer specialty in colleges and universities. An improved method based on SOPC is proposed to resolve the problem of the complex operation and fault detection in traditional experimental teaching. FPGA chip EP2C35F672C8 is used for basic platform where a complete computer system is designed by using VHDL including an 8086 CPU and original hard wire connection method is replaced with soft connection which is realized by electronic circuit in software environment of Quartus II. The practice shows that this method gives full play to the advantages of SOPC IP soft core, effectively avoiding the troubleshooting time and failure rate of hard wired and improving the interest of students and the efficiency of the experiment.
