CUP(中央处理器)是电脑中的重要部件,有人称之为“电脑的心脏”,近十余年来,CPU一直是计算机世界发展速度最快的技术产品领域。在这个发展过程中,In-tel公司的80×86系列CPU在为数庞大的IBM PC及其兼容机的支持下一度占据了市场的主流,但与80×86并行发展的摩托罗拉680×0系列CPU透过美国苹果电脑也始终保持着独树一帜的市场地位。从技术上看,80×86系列和68O×O系列都属于CISC技术体系,CISC是英文Complex Instruction Set Computer的缩写、译作“复杂指令系统电脑”。CISC技术在执行一个电脑指令时,需要经过多重演绎程序来实现CPU的各种功能。采用这种技术的CPU指令复杂繁多,虽然软件
CUP (central processor) is an important part of the computer, some people call it “the heart of the computer”, the CPU has been the fastest growing technology products in the computer world for more than ten years. In the course of this development, In-tel’s 80 × 86 series of CPUs dominated the market for the first time with the support of a large number of IBM PCs and their compatibles. However, with the 80 × 86 parallel development of the Motorola 680 × 0 series of CPUs Through the United States Apple Computer has always maintained a unique market position. From a technical point of view, 80 × 86 series and 68O × O series belong to the CISC technology system, CISC is the acronym for English Complex Instruction Set Computer, translated as “complex instruction system computer.” CISC technology in the implementation of a computer instruction, you need to go through multiple deductive programs to achieve the various functions of the CPU. The CPU instructions using this technique are numerous and complicated, though the software
