1769-L32C CPU, Central Processing Unit (CPU) As the computing and control core of the computer system, is the final execution unit of information processing and program operation. Since the emergence of CPU, it has made great progress in logical structure, operation efficiency and function extension.

Central processing unit (CPU), is one of the main equipment of electronic computers, the core accessories in computers. Its main function is to interpret computer instructions and process data in computer software. CPU is the core part of the computer that is responsible for reading instructions, decoding instructions and executing instructions. The 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.

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