Consider three different processors P1, P2, and P3 executing the same instruction set with the clock rates and CPIS given in the following table. Processor Clock rate CPI PI 2 GHz 1.2 P2 3 GHz 0.8 P3 4 GHz 2.0 a) Which processor has the highest performance expressed in instructions per second? b) If the processors each execute a program in 10 seconds, find the number of cycles and the number of instructions. c) You are trying to reduce the time by 30% but this leads to an increase of 20% in the CPI. What clock rate should you have in order to get this time reduction?
