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.

In a microcomputer system,the central processing unit(CPU) or processor is contained on a single chip called the microprocessor.
在微机系统中,中央处理单元(CPU)或处理器包含在称为微处理器的单片机上。
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).
微处理器要么安装在插入系统板的载体包上,要么包含在插入系统板上特殊插槽的墨盒中(见图1-6)。
The microprocessor is the "brains" of the computer system.
微处理器是计算机系统的“大脑。
It has two basic components:the control unit and the arithmetic-logic unit.
它有两个基本组成部分:控制单元和算术逻辑单元。
Functions of these two units have be mentioned in section 1.
第1节提到了这两个单位的职能。

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。
