Can a program with only .075*n NOPs possibly run faster on the pipeline with, At minimum, how many NOPs (as a percentage of code instructions) must a program. 2. latencies. Therefore, the fraction of cycles is 30/100. (At this, point, the branch instruction reaches the MEM stage and updates the PC with the correct, next in- struction.)
