What does the CPU perform to complete basic operations?

cpu completes basic operations by executing "instructions". Every time the computer's CPU executes an instruction, it completes a basic operation or judgment. In the CPU, the execution of an instruction includes three steps: instruction fetching, analysis and execution. Therefore, executing an instruction will complete a basic operation or judgment.

Central processing unit (CPU) is one of the main devices of electronic computers and the core component of computers. Its function is mainly to interpret computer instructions and process data in computer software. The CPU is the core component of the computer that reads instructions, decodes them, and executes them. The central processing unit mainly consists of two parts, namely the controller and the arithmetic unit, which also include cache memory and the data and control bus that realize the connection between them. The three core components of an electronic computer are the CPU, internal memory, and input/output devices. The main functions of the central processing unit are to process instructions, perform operations, control time, and process data. [2]

In the computer architecture, the CPU is the core hardware unit that controls and allocates all hardware resources of the computer (such as memory, input and output units) and performs general operations. The CPU is the computing and control core of the computer. The operations of all software layers in the computer system will eventually be mapped to CPU operations through the instruction set.
