Question: Consider two different processors P1 and P2 executing the same instruction set. P1 has 2.0 GHz clock rate and a CPI of 1.5 while P2

Consider two different processors P1 and P2 executing the same instruction set. P1 has 2.0 GHz clock rate and a CPI of 1.5 while P2 has 3.0 GHz clock rate and a CPI of 2.0. Show your work.

A. Which processor has higher performance expressed in instructions per second?

B. If P1 executes a program in 10 seconds, what are the number of clock cycles and the number of instructions executed? (do this only for P1)

C.We are trying to reduce the execution time by 20% (e.g., if original is 100 unit, the new is 80 unit) by this leads to an increase of 20% in the CPI. What clock rate should we have to get time reduction? (do this only for P1)
