概述 1971年美国英特尔公司研制成功了Intel4004微处理器及MCS—4型微计算机,迄今才近十年,但其发展极其迅速。4004是第一代四位微处理器,采用PMOS工艺,指令(指寄存器加法指令,下同)执行时间为10.8微秒。73年底英特尔公司开始生产8080,74年底莫托罗拉公司开始生产MC6800。这是目前广泛应用的代表第二代产品的八位微处理器,采用NMOS工艺,指令执行时间为1.3～2微秒,其它性能也大为改进。78年下半年来泽洛格公司制造了16位高性能的Z-8000系统,采用
Overview Intel Corporation in 1971 the United States successfully developed the Intel4004 microprocessor and MCS-4-type microcomputer, so far only ten years, but its development is extremely rapid. 4004 is the first generation of four microprocessors, the use of PMOS technology, instruction (referring to the register addition instruction, the same below) execution time of 10.8 microseconds. At the end of 73, Intel Corporation started production of 8080. At the end of 74, Motorola started production of the MC6800. This is an eight-bit microprocessor that is widely used today to represent the second-generation products. Using NMOS technology, the instruction execution time is 1.3 to 2 microseconds, and other features are greatly improved. In the second half of the 78th Zeloop created 16 high-performance Z-8000 systems for use
