What is the function of control unit of micro processor?

The control unit (CU) of a microprocessor directs the operation of the processor by managing the execution of instructions. It interprets the instruction set and generates control signals to coordinate the activities of the processor's components, such as the arithmetic logic unit (ALU), memory, and input/output devices. Essentially, the CU ensures that the correct sequence of operations is followed, enabling the microprocessor to perform tasks efficiently.
