电子计算机的应用已深入到国民经济的各个领域中.自从1964年世界上研制第一台诺伊曼式电子计算机以来,经历了电子管、晶体管、集成电路、大规模集成电路四代变化,但计算机的设计思想基本上是按照“程序存储”式来设计的,输入计算机的信息和控制计算机工作的指令及数据均采用二进制编码,并统一储存在存储器中.然后由控制器不断地从存储器中取出操作指令,再根据指令将有关信息送入运 Since the first Neumann electronic computer was developed in the world in 1964, it has undergone four generations of changes in electron tubes, transistors, integrated circuits and large-scale integrated circuits. However, the application of computers has penetrated into various fields of the national economy. The design concept is basically in accordance with the “program storage” type to design, enter the computer information and control computer work instructions and data are binary code, and unified storage in memory and then continuously removed from the controller by the memory Operation instructions, then according to the instructions will be sent to the relevant information
