Compilers can have a profound impact on the performance of an application on given a processor. This problem will explore the impact compilers have on execution time.

Assume the average CPIs found in 1.6.1, but that the compiled programs run on two different processors. If the execution times on the two processors are the same, how much faster is the clock of the processor running compiler A’s code versus the clock of the processor running compiler B’s code?
