| 摘 要： | 在控制器中设计新指令是控制器教学中比较难的内容。为解决TEC-XP16教学机缺少乘法指令和除法指令的问题,基于TEC-XP16教学机,介绍微程序控制器的基本组成与工作原理,分析在微程序控制器中扩展指令的主要过程,提出一种微程序控制器中MUL乘法指令与DIV除法指令的设计方案;以扩展MUL乘法指令为例,详细介绍在TEC-XP16教学机微程序控制器中设计实现扩展指令的完整过程;以实验方式验证了所设计和实现的乘法指令与除法指令的功能。所提出的设计方法对微程序控制器部件的教学与实验有一定的指导作用。

| Abstract: | It is difficult to design new instructions in controller teaching.This paper solved the problem that TEC-XP16 teaching machine lacked multiply and division instructions.Based on TEC-XP16 teaching machine,we introduced the basic composition and working principle of microprogram controller,analyzed the main process of extension instructions in microprogram controller,and proposed a design scheme of MUL instruction and DIV instruction in microprogram controller.Taking the extension MUL instruction as an example,we introduced the whole process of designing and implementing the extension instruction in TEC-XP16 teaching machine in detail.The functions of multiply and division instructions were verified by experiments.Our method has a certain guiding role in the teaching and experiment of microprogram controller components. |
