The central processing unit (CPU) is a large-scale integrated circuit that serves as the computing and control core of a computer. Its main function is to interpret computer instructions and process data in computer software. It mainly includes the arithmetic unit, cache memory, and the bus that implements the data, control, and state connections between them. It, along with internal memory and input/output devices, is collectively referred to as the three core components of an electronic computer.
