(5)微处理器的基本工作原理 1)微处理器的硬件结构特点从硬件上看,它是由一块大规模集成电路(MOS片)组成的电视机专用4位(或8位)微型计算机。由于它属于计算机的一种,所以其内部有中央处理单元即CPU运算器、控制器(包括算术逻辑运算单元、累加器、寄存器、程序计数器、地址寄存器、指令寄存器、总线结构电路等)和存储器(只读存储器ROM和随机存储器RAM)以及输入/输出(I/O)总线接口电路等。由
(5) The basic working principle of the microprocessor 1) The hardware structure of the microprocessor Features From the hardware point of view, it is composed of a large-scale integrated circuit (MOS chip) TV dedicated 4 (or 8) microcomputer . Because it belongs to a computer, so it has a central processing unit that is CPU processor, controller (including arithmetic and logic unit, accumulator, register, program counter, address register, instruction register, bus structure circuit, etc.) and memory (Read Only Memory ROM and Random Access Memory RAM), and input / output (I / O) bus interface circuits. by
