Question:

How often (as a percentage of all cycles) do we have a cycle in which all five pipeline stages are doing useful work?


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.Loop: b. Loop: ADD R1, R2, R1 LW R2,0 (R1) LW R2,16(R2) SLT R1, R2, R4 BEQ R1, R9, Loop LW R1,0(R1) AND R1,
