What Is a Central Processing Unit?

A central processing unit (CPU), as the computing and control core of a computer system, is the ultimate execution unit for information processing and program execution. Since its birth, the CPU has made tremendous progress in logical structure, operating efficiency, and functional extension. ^[1]

The central processing unit (CPU) is one of the main equipments of electronic computers and the core accessory in computers. Its function is mainly to interpret computer instructions and process data in computer software. The CPU is the core component in a computer responsible for reading instructions, decoding them, and executing them. The CPU mainly includes two parts, namely

CPU appears in

The powerful data processing function of the central processor has effectively improved the working efficiency of the computer. In the data processing operation, it is not just a simple operation. The operation of the central processor is based on the instructions given by computer users. During the execution of the instruction task, the control instruction input by the user is corresponding to the CPU. With the rapid development of China's information technology, computers have been widely used in people's life, work and corporate office automation. As a main control device,

The booming CPU has also brought many security issues. Appeared in 1994

The general-purpose central processing unit (CPU) chip is the basic component of the information industry and the core device of weapons and equipment. The lack of CPU technology and industry with independent intellectual property rights in our country not only results in the information industry being subject to people, but also national security is difficult to be fully guaranteed. During the 10th Five-Year Plan period, the National "863 Plan" began to support independent research and development of CPUs. During the "Eleventh Five-Year Plan" period, a major project of "Core Electronic Devices, High-end General-Purpose Chips and Basic Software Products" ("Nuclear High-Base") introduced the CPU achievements of the "863 Plan" into the industry. Starting from the "Twelfth Five-Year Plan" period, China has carried out independent research and development of CPU applications and trials in various fields, and formed an independent technology and industrial system within a certain range, which can meet the application needs of weapons and equipment, information technology and other fields. However, foreign CPUs have been monopolized for a long time, and it will take some time for China to independently develop CPU products and market maturity. ^[10]
