HardWired Control Unit:

• Hard-wired control unit is implemented as sequential logic circuit or finite state machine ( FSM) generates controls s/g to execute the instruction.
• It operates at faster clock rate and in less clock cycle then a soft wired control unit.

There are four techniques for design of hard wired control unit:

• State Table Method:
  • It is a standard algorithmic approach to design sequential circuit.
  • In this approach, it is necessary to design a state table & this stable table can be implemented by using finite state machine (FSM).
• This FSM has two types:
  • Mealy Type.
  • Moore Type.
