A microprocessor is a central processing unit composed of one or a few large-scale integrated circuits. These circuits perform the functions of control components and arithmetic logic components. Compared with traditional central processing units, microprocessors have the advantages of small size, light weight and easy modularization. The basic components of a microprocessor are: register stack, arithmetic unit, timing control circuit, and data and address bus. The microprocessor can complete operations such as fetching instructions, executing instructions, and exchanging information with external memory and logic components. It is the operation control part of the microcomputer. It can form a microcomputer with memory and peripheral circuit chips.
