　　中央處理器(Central Processing Unit，簡稱CPU)是電子計(jì)算機(jī)的主要設(shè)備之一，電腦中的核心配件。其功能主要是解釋計(jì)算機(jī)指令以及處理計(jì)算機(jī)軟件中的數(shù)據(jù)。IC698CPE010 CPU是計(jì)算機(jī)中負(fù)責(zé)讀取指令，對指令譯碼并執(zhí)行指令的核心部件。IC698CPE010 中央處理器主要包括兩個(gè)部分，即控制器、運(yùn)算器，其中還包括高速緩沖存儲器及實(shí)現(xiàn)它們之間聯(lián)系的數(shù)據(jù)、控制的總線。電子計(jì)算機(jī)三大核心部件就是CPU、內(nèi)部存儲器、輸入/輸出設(shè)備。中央處理器的功效主要為處理指令、執(zhí)行操作、控制時(shí)間、處理數(shù)據(jù)。

　　以下是關(guān)于CPU的一些關(guān)鍵特性：

　　控制器：IC698CPE010 負(fù)責(zé)從內(nèi)存中取出指令，并對指令進(jìn)行譯碼;根據(jù)指令的要求，按時(shí)間的先后順序，負(fù)責(zé)向其它各部件發(fā)出控制信號，保證各部件協(xié)調(diào)一致地工作，一步一步地完成各種操作。

　　運(yùn)算器：又稱算術(shù)邏輯單元(ALU)，是進(jìn)行算術(shù)、邏輯運(yùn)算的部件。

　　寄存器：CPU內(nèi)部臨時(shí)存儲數(shù)據(jù)的部件，其重要性僅次于CPU的“大腦”核心運(yùn)算部件——ALU(Arithmetic and Logic Unit，算術(shù)邏輯運(yùn)算單元)。寄存器的大小是CPU性能的一個(gè)重要指標(biāo)，它不僅關(guān)系到CPU內(nèi)部的執(zhí)行效率，也影響到整個(gè)微機(jī)系統(tǒng)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.
