The controller mainly consists of command components, timing components and what?

The controller is mainly composed of an instruction component, a timing component and a control component. The instruction component mainly completes the registration and decoding of instructions; the timing component generally consists of a three-level sequence of cycle, beat and work pulse, which provides the execution of instructions. Generate timing signals; the control component forms corresponding logical relationships according to the combination conditions, and then combines with the timing signals to generate the required control signals.

The controller refers to changing the wiring of the main circuit or control circuit in a predetermined sequence and changing the resistance value in the circuit to control the starting, speed regulation and braking of the motor. It is a reverse master device; its main task is to issue commands and play a coordinating and commanding role in the operation of the entire computer system.

The controller is an important part of the CPU, which consists of the instruction component, timing component and control component.

• The instruction component mainly completes the registration and decoding of instructions;

• The timing component generally consists of three levels of timing: cycle, beat and work pulse. It is composed of components that generate timing signals for the execution of instructions; the

• control components form corresponding logical relationships according to the combination conditions, and then combined with the timing signals, the required control signals can be generated.
