在四位机应用系统的设计中,除了进行必需的硬件电路(包括接口电路与辅助电路)设计之外,重要的一环是进行应用软件即专用程序的设计.下文先介绍基本的程序结构,然后介绍一些典型的实用程序.由于四位机的结构与指令都是大同小异的,因此掌握了一种四位机的编程方法后,再去掌握其它的四位机就轻而易举了.流程图是程序执行次序的图解表示,是描述程序的最好方法,也是帮助人们编制程序、交流程序设计思想的有力工具.流程图的各种基本符号都很明了易
In the four-bit machine application system design, in addition to the necessary hardware circuit (including interface circuit and auxiliary circuit) design, the important part is the application software that is dedicated program design.The following first introduces the basic program structure, And then introduce some typical utilities.Since the four-bit machine structure and instructions are more or less the same, so master a four-bit programming method, and then to grasp the other four-bit machine is easy.Flowchart is the program The graphical representation of the order of execution is the best way to describe the program and is also a powerful tool to help people program and communicate programming ideas. The basic symbols in the flowchart are straightforward
