CPU CPU controller controls the work

In the user view, unnecessarily detailed analysis of the internal circuitry of the CPU, but each part is working mechanism should be enough to understand. CPU CPU controller controls the work, cpu modules plc which it reads the instruction, the instruction interpretation and execution of instructions. However, the pace of work is controlled by the oscillation signal. Operator used for digital or logic operations, high-speed plc  working under the command of the controller. Register to participate in operations, and store intermediate result of the operation, it is also working under the command of the controller.
