支持9种工作模式的ARM寄存器堆结构设计方法

A Design Method of ARM Register Heap Structure Supporting Nine Working Modes

基于自主研发的ARMv7架构教学模型计算机,提出一种与MIPS和RISC-V不同的通用寄存器堆结构设计方法。采用在译码电路中添加工作模式控制等策略,能够支持ARM 9种工作模式。该方法是对非开源的ARM芯片中多工作模式寄存器堆设计技术的模拟实现,也为传统计算机组成原理课程,增添一种新的计算机部件设计方法。借助RSIE-SPOC教学方法和自制远程可交互式FPGA实验设备,设计了教学实施方案。课程调查表明,90.5%学生认为实验对理解ARM CPU结构有促进作用。

Based on the ARMv7 architecture teaching model computer which is self-made, this paper proposes a general register heap structure design method which is different from MIPS and RISC-V. It can support 9 working modes of ARM by adding the working-mode bits control in the decoding circuit. This method simulates and realizes the structure design of nine working modes register heap structure in non-open source ARM chip. This method also adds a new design method of computer components to the traditional course of principle of computer organization. With the help of RSIE-SPOC teaching method and self-made remote interactive FPGA experimental equipment, ateaching implementation scheme is designed. The course survey shows that 90.5% of the students believe that experiment can promote the understanding of ARM CPU structure.
