一、概述所谓微处理机(Microprocessor,简称μP)是指由一片或多片大规模集成电路组成的中央处理部件及其时钟脉冲发生器和系统控制器。所谓微型计算机(Microcomputer,简称μC)是指似微处理机为基础再配以随机存贮器(RAM)、只读存贮器(ROM)以及输入/输出(I/O)接口电路和相应的其它配套电路。现在已能够把上述各种片子制作在一个芯片上,即所谓单片微型机。所谓微型计算机系统(Microcomputer System,
I. Overview The so-called microprocessor (Microprocessor, referred to as μP) refers to one or more large-scale integrated circuits consisting of central processing unit and its clock pulse generator and system controller. The so-called Microcomputer (Microcomputer, referred to as μC) refers to the microprocessor-based and then with random access memory (RAM), read only memory (ROM) and the input / output (I / O) interface circuit and the corresponding Other supporting circuits. It is now possible to make these various films on a single chip, the so-called one-chip microcomputer. The so-called microcomputer system (Microcomputer System,
