This article is about which two parts the CPU CPU of the computer includes. The editor thinks it is very practical, so I share it with you. I hope you can get something after reading this article. Let's take a look at it with the editor.

The CPU of the computer consists of an arithmetic unit and a controller, in which the main function of the arithmetic unit is to perform arithmetic and logic operations, and the controller is composed of a program counter, an instruction register, an instruction decoder, a timing generator and an operation controller. It is a "decision-making body" that issues commands, that is, to coordinate and direct the operation of the whole computer system.

The central processing unit (CPU) of the electronic computer consists of two parts: the arithmetic unit and the controller.

Functions of the arithmetic unit:

The main function of the arithmetic unit is to perform arithmetic operation and logic operation. The arithmetic unit includes arithmetic logic unit (ALU), accumulator, state register and general register. The arithmetic logic operation unit is responsible for four operations, and, OR, non, XOR and other logical operations.

The data processed by the arithmetic unit comes from the memory; the processed result data is usually sent back to the memory or temporarily stored in the arithmetic unit. Together with Control Unit, it forms the core part of CPU.

Functions of the controller:

The controller consists of a program counter, an instruction register, an instruction decoder, a timing generator and an operation controller. It is a "decision-making body" that issues commands, that is, to coordinate and direct the operation of the whole computer system.

These are the two parts of the computer's central processing unit (CPU). The editor believes that there are some knowledge points that we may see or use in our daily work. I hope you can learn more from this article. For more details, please follow the industry information channel.
