What are the main components of CPU
Central processing unit (CPU) is one of the main equipment of electronic computer and the core accessory of computer. Its function is mainly to interpret computer instructions and process data in computer software. CPU is the core component of the computer which is responsible for reading instructions, decoding instructions and executing instructions. The central processing unit mainly includes two parts: controller and arithmetic unit, which also includes cache memory and data and control bus to realize the connection between them. The three core components of electronic computer are CPU, internal memory and input / output equipment. The main functions of CPU are processing instructions, executing operations, controlling time and processing data.
The main components of CPU are controller and arithmetic unit; The controller consists of program counter, instruction register, instruction decoder, timing generator and operation controller; The basic operations of the arithmetic unit include addition, subtraction, multiplication and division, and, or, non, XOR and other logical operations.
The CPU mainly includes two parts: controller and arithmetic unit, which also includes cache memory and data and control bus to realize the connection between them.
The basic operations of the arithmetic unit include addition, subtraction, multiplication and division, logical operations such as and, or, non and XOR, and operations such as shift, comparison and transmission, also known as arithmetic logic unit (ALU).
The controller is composed of program counter, instruction register, instruction decoder, timing generator and operation controller. It is the "decision-making body" to issue commands, that is, to coordinate and command the operation of the whole computer system.
In the computer architecture, CPU is the core hardware unit that controls and allocates all hardware resources of the computer (such as memory, input and output units) and performs general operations. The core of CPU and operation is computer control. The operation of all software layers in the computer system will eventually be mapped to the operation of CPU through instruction set.
It can be seen that the importance of CPU in electronic equipment. If the CPU does not operate normally, it will lead to very serious consequences. Heat dissipation also plays a key role in the performance of CPU. Most electronic components fail due to high temperature. Having a good heat dissipation system is indispensable to the stability system of electronic equipment. Necessary thermal design is also needed while designing electronic products.
