Electrical Engineering

Consider three different processors P1, P2, and P3 executing thesame instruction set.

P1 has a 3 GHz clock rate and a CPI of 1.5.

P2 has a 2.5 GHz clock rate and a CPI of 1.0.

P3 has a 4.0 GHz clock rate and has a CPI of 2.2.

a. Which processor has the highest performance expressed ininstructions per second?

b. If the processors each execute a program in 10 seconds, findthe number of cycles and the number of instructions.

c. We are trying to reduce the execution time by 30%, but thisleads to an increase of 20% in the CPI. What clock rate should wehave to get this time reduction?
