多台微机并行工作,首先遇到的问题就是如何实现微机之间的通讯,即接口软件的研制.本文选用Z80微机作为描述算法的样机,使用Z80汇编语言来给出一实现通讯算法的程序.一般来说,单板机都带有并行输入/输出接口PIO,以DBJ-Z80为例,其PIO地址:80H:A数据寄存器;
The first problem encountered in parallel operation of multiple computers is how to realize the communication between the two computers, that is to say, the development of the interface software.In this paper, the Z80 microcomputer is chosen as the prototype to describe the algorithm, and the Z80 assembly language is used to give a program to realize the communication algorithm. In general, the single board machine with parallel input / output interface PIO to DBJ-Z80, for example, the PIO address: 80H: A data register;
