摘　　要：针对目前高校计算机系统各课程实验衔接不紧密、实验成本较高的问题,提出设计基于小型FPGA开发板、以RISC-V CPU和Rust操作系统内核为核心的计算机系统综合实验平台。硬件实验以在低成本FPGA芯片上搭建picorv32 RISC-V CPU为核心,软件实验以在硬件实验基础上移植Rust编写的rCore教学操作系统为核心。以较低成本在同一平台完成计算机组成原理与操作系统实验设计,使其形成一个有机的整体,在资源与成本有限的情况下构建一个较为完整的实验体系。实例结果表明,实验平台以软硬件协作的方式,适应技术的发展,及时更新实验内容,可满足高校计算机系统教学综合实验的基本要求。Aiming at trying to improve the experimental connection among the computer system courses in the universities and reduce the experiment cost,a comprehensive computer system experimental platform based on a small FPGA board and a teaching operation system was proposed.The hardware experiment was building a system on chip(SoC)with picorv32 RISC-V CPU on a low-cost FPGA chip.The software experiment was transplanting the rCore teaching operation system written by Rust on their own SoC.The computer composition principle and operation system experimental design on the same platform at a lower cost was completed,and an organic whole was formed.The experimental system was a relative complete platform with limited costs.Examples show that,the experimental contents are timely updated for tracing computer technology trends in a software-hardware cooperative manner to meet the basic requirements of computer system teaching experiments in universities.
