CPU (Center Processing Unit) central Processing Unit (CPU) is the core core and control the operation of a computer, CPU by Arithmetic Unit (Arithmetic), the Controller (Controller), Register (Register), and the data between them, the state of the control and Bus (Bus),
The CPU features are: 1. The main frequency, the CPU clock frequency, in general, the higher the frequency, the higher the overall operation efficiency of the machine,
2. Cache (Cache), mainly divided into external and internal Cache Cache, internal Cache is enclosed within the CPU Cache, used for temporary storage of CPU computing when part of the instructions and data access speed is consistent with the CPU frequency,
External cache, CPU external cache,
CPU is widely applied in AI, VR, big data cloud computing, industrial machinery automation, biomedical, aerospace and other aspects of the application of very much, with the development of CPU technology, chip technology as a new symbol of national science and technology ability, so it is very important to the development of the CPU,
