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:
