Consider three different processors p1, p2, p3 executing the same set of instructions. p1 has a 3 ghz clock rate and a cpi of 1.5. p2 runs at 2 ghz and has a cpi of 1.2. p3 has a 4 ghz clock rate and a cpi of 2.4.1. which processor has the highest performance expressed in instructions per second?
2. if the processors each execute a program in 10 seconds, find the number of cycles and the number of instructions.3. 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?
