　　中央处理器(Central Processing Unit，简称CPU)是电子计算机的主要设备之一，电脑中的核心配件。其功能主要是解释计算机指令以及处理计算机软件中的数据。IC698CPE010 CPU是计算机中负责读取指令，对指令译码并执行指令的核心部件。IC698CPE010 中央处理器主要包括两个部分，即控制器、运算器，其中还包括高速缓冲存储器及实现它们之间联系的数据、控制的总线。电子计算机三大核心部件就是CPU、内部存储器、输入/输出设备。中央处理器的功效主要为处理指令、执行操作、控制时间、处理数据。

　　以下是关于CPU的一些关键特性：

　　控制器：IC698CPE010 负责从内存中取出指令，并对指令进行译码;根据指令的要求，按时间的先后顺序，负责向其它各部件发出控制信号，保证各部件协调一致地工作，一步一步地完成各种操作。

　　运算器：又称算术逻辑单元(ALU)，是进行算术、逻辑运算的部件。

　　寄存器：CPU内部临时存储数据的部件，其重要性仅次于CPU的“大脑”核心运算部件——ALU(Arithmetic and Logic Unit，算术逻辑运算单元)。寄存器的大小是CPU性能的一个重要指标，它不仅关系到CPU内部的执行效率，也影响到整个微机系统的性能。

　　Central Processing Unit (CPU) is one of the main devices of the electronic computer, the core accessories in the computer. Its main function is to interpret computer instructions and process data in computer software. IC698CPE010 CPU is the core part of the computer responsible for reading instructions, decoding instructions and executing instructions. IC698CPE010 central processing unit mainly includes two parts, that is, the controller, the arithmetic device, which also includes the cache memory and the data and control bus that realize the connection between them. The three core components of an electronic computer are CPU, internal memory, and input/output devices. The main functions of the central processor are to process instructions, perform operations, control time, and process data.

　　Here are some key features about the CPU:

　　Controller: IC698CPE010 is responsible for retrieving instructions from memory and decoding the instructions; According to the requirements of the instructions, in order of time, responsible for sending control signals to other components to ensure that the components work in harmony and complete various operations step by step.

　　Arithmetic unit: Also known as arithmetic logic unit (ALU), is a component for arithmetic and logic operations.

　　Register: A part of the CPU that temporarily stores data, second only to the CPU's "brain" core Arithmetic Unit, the ALU (Arithmetic and Logic Unit). The size of register is an important indicator of CPU performance, which is not only related to the execution efficiency of CPU, but also affects the performance of the whole microcomputer system.
