一、概 述 INTEL8080微处理机是INTEL公司1974年研制成功的产品,8080是集成电路芯片的型号(它相当于一般计算机中的中央处理装置CPU)由于它在性能上比早先的8008芯片提高了一级,指令执行时间由20μS提高到2μS,指令系统由48条增加为78条,使微处理机达到了工业实用阶段,并很快在工业上得到了广泛应用。虽然以后许多公司也 I. Overview INTEL8080 microprocessor is INTEL company successfully developed in 1974 the product, 8080 is the integrated circuit chip model (which is equivalent to the general computer CPU) due to its performance than the previous 8008 chip increased by one Level, the instruction execution time increased from 20μS to 2μS, the instruction system increased from 48 to 78, so that the microprocessor reached the industrial practical stage, and soon has been widely used in industry.
