1、前言目前微型计算机的普及发展十分迅速,在民用产品中的应用成果也相继发表了许多文章。近一两年来微型机特别引人注目的发展趋势,是各种应用的多样化。可以予料在短时间内,微型机将朝着价格低廉的低档型和多功能型的两极分化的方向发展。本文介绍的8086微型机,是多功能型的代表,可以说是名符其实的第四代微型机。该机在制造工艺上,采用了业已成熟的2147型等存贮器中的高性能 MOS(HMOS)技术,在一芯片上集成了大约两万只晶体管。另一方面在体系结构上,考虑了跟8080A/
1, Preface At present, the popularization and development of microcomputer is very rapid. Many achievements have been published in the application of civil products. In the past one or two years, the special trend of development of microcomputers is the diversification of various applications. Can be expected in a short period of time, the minicomputer will move toward the low-cost low-end and multi-functional type of polarization direction. This article describes the 8086 microcomputers, is a multi-functional representatives, can be said to be truly fourth-generation microcomputers. The machine uses a high performance MOS (HMOS) technology in the proven 2147-type memory in manufacturing processes, integrating approximately 20,000 transistors on a single chip. On the other hand in the architecture, consider the 8080A /
