Consider the following data path diagram:
(a) Discuss the functionality of the RegDst and the ALUSrc control wires.
(b) Next, modify the diagram to indicate the datapath changes (and any additional multiplexing) needed to provide bypassing from EX to EX for all possible RAW hazards on arithmetic instructions. How does ALUSrc change when bypassing is added?
