At the start of the cycle in which we fetch the first instruction of the third iteration
Question:
At the start of the cycle in which we fetch the first instruction of the third iteration of this loop, what is stored in the IF/ID register?
The remaining three problems in this exercise refer to the following loop. Assume that perfect branch prediction is used (no stalls due to control hazards), that there are no delay slots, and that the pipeline has full forwarding support. Also assume that many iterations of this loop are executed before the loop exits.
