IC695CPU320中央处理器

IC695CPU320中央处理器（Central Processing Unit，CPU）是一块超大规模的集成电路，是计算机的运算和控制核心，其作用类似于人脑，负责对数据的加工处理和各种控制信号的发送。主要功能是解释执行计算机指令来完成计算，基本功能是指令顺序控制、操作控制、时间控制和数据加工。中央处理器与内部存储器和输入/输出设备合称为电子计算机三大核心部件。

IC695CPU320中央处理器主要包括运算器、控制器、高速缓冲存储器（Cache），以及实现它们之间联系的数据、控制其状态的总线。其中，运算器用于完成算术运算、逻辑运算和数据传送等数据加工处理任务；控制器根据存放在存储器中的指令序列（程序）进行工作，并由一个程序计数器控制指令的执行。

IC695CPU320中央处理器的运作原理可以分为四个阶段：提取（Fetch）、解码（Decode）、执行（Execute）和写回（Writeback）。中央处理器从存储器或高速缓冲存储器中取出指令、放入指令寄存器，并对指令译码、执行指令。中央处理器的发展经历了真空管、晶体管、集成电路、大规模集成电路、超大规模集成电路几个时代。

中央处理器著名厂商有Intel和AMD公司，Intel公司的主要CPU系列产品有赛扬、奔腾、酷睿、至强、凌动等，AMD主要有闪龙，速龙，羿龙，A10，FX等系列CPU产品。

IC695CPU320 CPU

IC695CPU320 Central Processing Unit (CPU) is a large scale integrated circuit, is the computing and control core of the computer, its role is similar to the human brain, responsible for data processing and the transmission of various control signals. The main function is to interpret and execute computer instructions to complete the calculation, and the basic function is instruction sequence control, operation control, time control and data processing. The central processing unit, together with internal memory and input/output devices, is called the three core components of the electronic computer.

The IC695CPU320 central processing unit mainly includes an arithmetic unit, a controller, a Cache, and the data that connects them and the bus that controls their state. Among them, the arithmetic device is used to complete the data processing tasks such as arithmetic operation, logic operation and data transmission. The controller works according to a sequence of instructions (programs) stored in memory, and a program counter controls the execution of the instructions.

The operating principle of the IC695CPU320 CPU can be divided into four stages: Fetch, Decode, Execute and Writeback. The central processor takes out the instructions from the memory or cache, puts them into the instruction register, interprets and executes the instructions. The development of the central processing unit has experienced several times: vacuum tubes, transistors, integrated circuits, large-scale integrated circuits, and very large scale integrated circuits.

CPU famous manufacturers are Intel and AMD company, Intel company's main CPU series products are Celeron, Pentium, Core, Xeon, Atom, etc. AMD mainly has Shantiron, Speeddragon, Yilong, A10, FX and other series CPU products.
