Question

What is the speedup of going from a 1-issue processor to a 2-issue processor? use your code from part a for both 1-issue and 2-issue, and assume that 1,000,000 iterations of the loop are executed. as in part b, assume that the processor has perfect branch predictions, and that a 2-issue processor can fetch any two instructions in the same cycle?

Answer 1

I think it is sped up by around 0.6 GHz
