二、CPU的功能 1. 执行指令：CPU能够执行各种指令，包括算术运算、逻辑运算、控制流等。 2. 处理数据：CPU通过高速缓存和主存储器等部件，对数据进行读取、存储和传输。 3. 控制电脑运行：CPU负责控制电脑中各个硬件的协调工作，确保电脑正常运行。 三、CPU的组成 CPU主要由控制器、运算器和寄存器组成。控制器负责读取指令并控制运算器的操作；运算器则负责执行各种算术和逻辑运算；寄存器则用于存储数据和指令。 四、CPU的翻译（英文版） Understanding the Brain of a Computer - CPU In a computer, there is an indispensable component that is aptly described as the "brain" of the computer - the CPU (Central Processing Unit). The CPU is the core component of a computer, responsible for executing various instructions and processing data, enabling the computer to operate normally.

I. What is a CPU? CPU, or Central Processing Unit in English, is an integrated circuit that contains billions of tiny transistors. These transistors perform logical operations and data processing through interconnections, realizing various functions of a computer. II. Functions of a CPU 1. Executing instructions: The CPU can execute various instructions, including arithmetic operations, logical operations, control flow, etc. 2. Processing data: The CPU reads, stores, and transmits data through high-speed caches and main memories. 3. Controlling computer operation: The CPU is responsible for controlling the coordinated operation of various hardware in a computer, ensuring the normal operation of the computer. III. Composition of a CPU A CPU is mainly composed of a controller, an arithmetic logic unit (ALU), and registers. The controller reads instructions and controls the operation of the ALU; the ALU performs various arithmetic and logical operations; and registers are used to store data and instructions.
