The composition of CPU: 1. Registers, used to temporarily store processing objects such as instruction data; 2. Controller, read instructions, data, etc. in the memory into registers; 3. Arithmetic unit, responsible for calculations from memory Read the data in the register; 4. Clock, responsible for sending the clock signal for the CPU to start timing.

Composition of cpu
Concept: Among the components of a computer, the device that performs data operations according to the instructions of the program and controls the entire computer is called the CPU.
The CPU is internally composed of four parts: registers, controllers, operators and clocks. Each part is connected to each other by current signals.
Registers can be used to temporarily store processing objects such as instruction data and can be regarded as a type of memory. There are 20 to 100 registers inside a CPU.
The controller is responsible for reading instructions, data, etc. from the memory into registers, and controlling the entire computer based on the execution results of the instructions.
The operator is responsible for computing the data read from the memory into the register.
The clock is responsible for sending the clock signal for the CPU to start timing. There are also computers where the clock is located outside the CPU.
