2-1.Microprocessors

2-1.Microprocessors In a microcomputer system,the central processing unit(CPU) or processor is contained on a single chip called the microprocessor.The microprocessor is either mounted onto a carrier package that plugs into the system board or contained within a cartridge that plugs into a special slot on the system board (See Figure1-6).The microprocessor is the "brains" of the computer system. It has two basic components:the control unit and the arithmetic-logic unit. Functions of these two units have be mentioned in section 1.1 of this textbook.

在微型计算机系统中，中央处理器（CPU）或称处理器，包含在一个芯片上，又称为微处理器。微处理器即可以安装在插入到主板上的承载插件上，也可以安装在插入到主板专用插槽的盒上，如图1-6所示。微处理器是计算系统的“大脑”。它有两个基本部件：控制器和算术-逻辑部件。这两个部件的功能已在本书的1.1节中介绍过。
