Consider three processors (p1, p2, p3), each with the same instruction set. p1 has a 2.0 ghz clock rate and a cpi of 1.5. p2 has a 2.5 ghz clock rate and a cpi of 2.0. p3 has a 4.0 ghz clock rate and a cpi of 2.5.
a) compute the instructions per second for each processor.
b) for each processor executing a different program in 10 seconds, compute the number of cycles and the number of instructions that were performed.
c) for each processor executing the programs in part b, the cpi is increased by 20%. we now wish to reduce the execution time by 30%. what should the new clock rate be for each processor?
