Consider three different processors P1, P2, and P3 executing the same instruction set. P1 has a 3GHz clock rate and a CPI of 1.5. P2 has a 2.5GHz clock rate and a CPI of 1.0, P3 has a 4GHz and a CPI of 2.5.
a)Which processor has the highest performance expressed in instructions per second?
b)If the processors each execute a program in 5seconds, find the number of cycles and the number of instructions.
c)We are trying to reduce the execution time by 20% but this leads to an increase of 15% in the CPI. What clock rate should we have to get this time reduction?
