Consider three different processors P1, P2 and P3 executing the same instruction set with the clock rates and CPIs give in the following table. Processor Clock Rate CPI a. | P1 3 GHz 1.5 P2 2.5 GHZ 1.0 P3 4GHz 2.2 1) Which processor has the highest performance expressed in instructions per second? If the processors each execute a program in 10 seconds, find the number of cycles and the number of instructions. We are trying to reduce the time by 30% but this leads an increase of 20% in the CPI. What clock rate should we have to get this time reductions
