摘要
本文首先基于TEC-XP16教学机,介绍了在组合逻辑控制器中扩展指令的主要过程。然后,以扩展SWRR指令为例,详细介绍了如何在控制器的源文件中添加扩展指令的控制信号的逻辑表达式、编译控制器的源文件、对MACH器件进行编程、编写程序验证扩展指令是否正确的整个过程。本文对控制器部件的教学实验有一定的指导作用。
This paper introduces the main process of expand new instructions in combinational logic controller.Then,taking the expansion of instruction SWRR as an example,this paper describes the whole process of how toadd logical expressions for the control signals of expanded instructions in the source file of the controller,compilethe source file of controller,program MACH devices and write programs to verify that the expanded instructions arecorrect. This paper can serve as a significant guide in the teaching and experiments of controller component.
