微处理机自十七年代初发明以来,迅速获得了广泛的应用。国内微型机应用方面的工作也正在积极开展,拥有微型机的用户愈来愈多。但是,在发展一个微型机系统的工作过程中,除了硬件的设计安装外,还要编制各种管理程序和用户程序,而这些程序最终都是要放在存贮器中的。即使是在一个最小的微型机系统中,除了微处理器(μpu)以外,存贮器是必不可少的组成部分。在微型机系统中用到的存贮器有只读存贮器(ROM)和读/写存贮器(RAM)两大类。RAM用于存贮各种数据、信息以及某些服务程序。此外,在编制程序的过程中,RAM用于程序的调试。程序调通以后再把程序记录在磁带或软磁盘中,或者写到ROM中
Microprocessors have been rapidly gaining widespread adoption since their invention in the early 1700s. Domestic micro-computer applications are also actively involved, with more and more users of micro-computer. However, in the course of developing a microcomputer system, in addition to the hardware design and installation, various management programs and user programs have to be compiled, and these programs are ultimately stored in memory. Even in the smallest microcomputers, memory is an integral part of the microprocessor in addition to the μpu. The memory used in the microcomputer system has two major categories: read-only memory (ROM) and read / write memory (RAM). RAM is used to store a variety of data, information and some service programs. In addition, RAM is used for program debugging during programming. After adjusting the program and then recorded in the tape or floppy disk, or write to ROM
