AI Infra HPC — CPU

The Basic components of a CPU Nowadays, CPUs have evolved to the point where they integrate large-scale and complex circuits. It can be regarded as a complex machine assembled by many work units. However, no matter how the specific implementation of the CPU changes or how many times the number of transistors increases, it can be roughly divided into three main parts from a functional perspective: arithmetic logic unit , storage unit , and control unit . Of course, the image below is just a simplified diagram. Actually, the central Arithmetic and Logic Unit(ALU) has extremely complex wiring, the entire I/O, and the entire specific control flow. The following section will introduce these units and how they collaborate. with each other. Arithmetic and Logic Unit(ALU) The main function of CPU is to perform calculations, which is implemented through the Arithmetic and Logic Unit (ALU). An ALU circuit is internally composed of an arithmetic unit (AU) and a logic unit (LU), which can perform
