Which statement correctly describes a hardwired control unit?

Options

  • A. It generates control signals using fixed logic circuits
  • B. It requires every instruction to be stored as a microprogram
  • C. It is always slower than a microprogrammed control unit
  • D. More than one of the above
  • E. None of the above

Correct Answer (Detailed Explanation is Below)

A. It generates control signals using fixed logic circuits

Detailed Explanation

Correct Answer: It generates control signals using fixed logic circuits.

Explanation: A hardwired control unit uses logic gates, decoders, flip-flops, and other digital circuits to generate control signals. It is generally fast but less flexible to modify than a microprogrammed control unit.
