What are the functional requirements of control unit?

The control unit (CU) is responsible for directing the operation of the processor by managing the execution of instructions. Its functional requirements include fetching instructions from memory, decoding them to understand the required actions, and generating control signals to coordinate the operation of the CPU, memory, and input/output devices. Additionally, it ensures proper sequencing of instructions and manages data flow within the system to maintain efficient processing. Overall, the CU acts as the brain of the CPU, orchestrating all activities to ensure smooth and efficient operation.
