The composition of cpu
Concept: in the constituent components of a computer, the device that performs data operations according to the instructions of the program and controls the whole computer is called CPU.
The interior of CPU consists of four parts: register, controller, arithmetic unit and clock, and each part is connected by current signals.
Registers can be used to temporarily store instruction data and other processing objects, which can be regarded as a kind of memory. There are 20,100 registers inside a CPU.
The controller is responsible for reading the instructions and data in the memory into the register and controlling the whole computer according to the execution result of the instruction.
The arithmetic unit is responsible for calculating the data read into the register from memory.
The clock is responsible for sending out the clock signal that the CPU starts timing. There are also some computers whose clocks are located outside the CPU.
Thank you for your reading, the above is the content of "what is the composition of cpu", after the study of this article, I believe you have a deeper understanding of what the composition of cpu is, and the specific use needs to be verified in practice. Here is, the editor will push for you more related knowledge points of the article, welcome to follow!
