What is a CPU?

The CPU includes operational logic components, register components, and control components. English logic components; operational logic components can perform fixed-point or floating-point arithmetic operations, shift operations, and logical operations, and can also perform address operations and conversions. ^[1]

Register parts, including

English Control unit; The control unit is mainly responsible for decoding the instructions and issuing the operations to complete each instruction

Intel and AMD

English Perform an action; the function of an instruction is often realized by a sequence of operations performed by components in the computer. The CPU should generate corresponding operation control signals according to the functions of the instructions and send them to the corresponding components, so as to control these components to operate according to the requirements of the instructions. ^[1]

English Control time; time control is the timing of the implementation of various operations. During the execution of an instruction, what operations should be performed at any time should be strictly controlled. Only then can the computer work methodically. ^[1]

That is, performing arithmetic and logical operations on data, or performing other information processing.

Its function is mainly to interpret computer instructions and process data in computer software and execute instructions. Microcomputer is also called microprocessor. All operations of computer are controlled by CPU. The performance index of CPU directly determines the performance index of computer system. The CPU has the following four basic functions: data communication, resource sharing, distributed processing, and providing system reliability. The operating principle can be basically divided into four stages: Fetch, Decode, Execute, and Writeback. ^[1]
