CPU, also called Central Processing Unit, is the abbreviation of three initials of Central Processing Unit in English. It is a very large scale integrated circuit, and it is also the computing core and control unit of a computer. It mainly includes arithmetic unit, cache memory and bus to realize data, control and status among them. Together with memory and input and output devices, it is called the three core components of electronic computer. Its function is mainly to interpret computer instructions and process data in computer software.
CPU mainly includes arithmetic logic unit, register unit and control unit. First of all, talk about the arithmetic and logic components in the physical structure of CPU. The English name of this component is logic components. It can perform fixed-point or floating-point arithmetic operations, shift operations and logical operations, as well as address operations and conversions. It is the execution unit of central processing unit (CPU) and the core component of all CPU. It is an arithmetic logic unit composed of AND gate and OR gate. Its main function is to perform two-bit arithmetic operations, such as addition, subtraction and multiplication (excluding integer division). Basically, in all modern CPU architectures, binary is represented in the form of complement.
