基于CPLD的计算机组成原理实验板

Experimental Board for the Course of Computer Principles Based on CPLD

针对传统的计算机组成原理实验仪只能进行功能实现和验证,无法满足在校学生自主设计和创新问题,提出了一种改进计算机组成原理实验板的方法.该方法采用复杂可编程逻辑器件(CPLD)芯片替代传统分立小规模集成IC芯片作为载体,使用电子设计自动化(EDA)开发工具,以硬件描述语言(VHDL)来实现各种硬件逻辑,再与硬件的输入输出接口线路相连,最终组成一台可用于实验教学的完整计算机系统.实验表明,新设计的实验板能够实现原实验仪的实验要求,增强实验系统的功能,提高系统的灵活性,降低实验成本.

The problem of a traditional experimental instrument for the course of computer principles is that it can only be used for the functions of realization and vertification and cannot meet the requirement for students＇ independent design and innovation. A method for improving the experimental board of computer organization is proposed. The method uses a complex programmable logic device（CPLD） chip to replace the traditional discrete small-scale IC chip as the carrier. By using electronic design automation（EDA） tools and very-high-speed integrated circuit hardware description language（VHDL） it can achieve a variety of hardware logic, and connection with the input and output hardware interface circuits. The final composition with a complete computer system can be used for experimental teaching. Experiments show that the new experimental board can achieve the experimental requirements of original experimental instrument, enhance the function of the experimental system, improve flexibility and reduce test costs.
