What is a hardwired control unit?
Think about the difference between hardware and software.
Define what a finite state machine is.
Recall that it has finite states.
What does a hardwired control unit primarily use to generate control signals?
Think about what 'hardwired' means in terms of flexibility.
True or False? Hardwired control units are flexible and easily reprogrammable.
Consider the nature of hardware compared to software.
Design a finite state machine suitable for executing a series of arithmetic operations (e.g., ADD, SUBTRACT). Outline the key states and transitions.
Think about what each arithmetic operation entails.
Review the advantages of a hardwired control unit. Given a specific computational need, argue whether a hardwired or microprogrammed unit would be more effective.
Evaluate the context clearly.
