Question: A processor P3 has a 4.0 GHz clock rate and has a CPI of 2.2. a) If the processor executes a program in 20 seconds,

A processor P3 has a 4.0 GHz clock rate and has a CPI of 2.2.

a) If the processor executes a program in 20 seconds, find the number of cycles and the number of instructions.

b) What is the MIPS rate for the processor?

c) If we are trying to reduce the execution time by 30% but this leads to an increase of 20% in trhe CPI. What clock rate should we have to get this time reduction?
