Explanation:
Detailed explanation-1: -The hardwired control consists of a combinational circuit that outputs desired controls for decoding and encoding functions. The instruction that is loaded in the IR is decoded by the instruction decoder. If the IR is an 8-bit register, then the instruction decoder generates 28 (256) lines.
Detailed explanation-2: –Hardwired control unit is a digital circuit that generates the control signals by using combinational logic circuits.-These control signals are generated by the use of logic gates, decoders, and multiplexers.
Detailed explanation-3: -The control memory is absent in a hardwired control unit and present in a microprogrammed control unit.
