Q. Make an instruction execution feasible?
What are the functions that a control unit performs to make an instruction execution feasible? Instruction execution is achieved by executing micro-operations in a specific sequence. For different instructions this sequence can be different. So the control unit should perform two elementary functions:
However how are these two tasks achieved? The control unit produces control signals which in turn are responsible for achieving the above two tasks.
