What is the computer data processing center and the highest execution unit?

Central processing unit (CPU), as the operation and control core of computer system, is the final execution unit of information processing and program running. Since its birth, CPU has made great progress in logical structure, operating efficiency and function expansion.

CPU appeared in the era of large-scale integrated circuits, and the iterative update of processor architecture design and the continuous improvement of integrated circuit technology promoted its continuous development and improvement. Since its birth, CPU has been developing rapidly, from being dedicated to mathematical computing to being widely used in general computing, from 4-bit to 8-bit, 16-bit, 32-bit processor, and finally to 64-bit processor, from the incompatibility of various manufacturers to the emergence of different instruction set architecture specifications.
