Consider three different processors p1, p2, and p3 executing the same 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 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) we are trying to reduce the execution time by 30% but this leads to an increase of 20% in the cpi. what clock rate should we have to get this time reduction?
