3.1 概述微型计算机的整个内部逻辑虽然是十分复杂的,但由于采用了大规模集成电路,使硬件简化为少数几种标准器件,加上在第四章中将要介绍的功能灵活的可编程序接口电路后,使得微型计算机系统的硬件变得十分简单。近期MOTOROLA公司更新研制出与060系列机功能相当的单片微型计算机,例如MC6801单片机内,包含了CPU及其全部支持器件,128字节的RAM和2K字节的ROM以及串行和并行输入输出接口。而 3.1 Overview Microcomputer’s overall internal logic is very complex, but due to the use of large-scale integrated circuits, the hardware simplified to a few standard devices, coupled with the fourth chapter will introduce the function of flexible programmable interface After the circuit, the hardware of the microcomputer system becomes very simple. Recent MOTOROLA company to develop and develop similar to the 060 series of single-chip microcomputers, such as MC6801 microcontroller, contains the CPU and all its supporting devices, 128 bytes of RAM and 2K bytes of ROM and serial and parallel input and output interface. and
