摘　　要：针对现有微机原理实验平台固化,实验内容与数字电路基础知识脱节等问题,基于自主开发的可重构微处理器实验平台设计了新的实验案例。实验以FPGA为核心器件,运用硬件描述语言结合数字电路基础知识在FPGA中实现一个微处理器,在此基础上设计存储器和接口电路,根据外围部件设计汇编语言程序,实现步进电机的启停和旋转控制。设计的实验案例有效地融合了“数字电路”与“微机原理”的核心知识点,有助于考察学生融会贯通的能力。In view of the problems of the current microcomputer principle experimental platform being fixed and the experimental instance and the knowledge of digital circuits being disconnected,a new experimental instance based on self-developed reconfigurable microprocessor experimental platform is proposed.The designed experimental instance uses FPGA as the core device,the hardware description language combined with basic knowledge of digital circuit is exploited to implement a microprocessor in FPGA.On this basis,storage and interface circuits are designed,and assembly language programs are designed to control the start,stop,and rotation speed of the step motor.The proposed experimental instance effectively integrates the core knowledge of"Digital Circuits"course and"Microcomputer Principles"course,which can be utilized to examine students'ability to integrate and apply knowledge.
