Let there are three different processors P1, P2, and P3 executing the same instruction set. P1 has a 3.3 GHz clock rate and a CPI of 1.6. P2 has a 2.8 GHz clock rate and a CPI of 1.2. P3 has a 4.0 GHz...

Let there are three different processors P1, P2, and P3 executing the same instruction set. P1 has a 3.3 GHz<br>clock rate and a CPI of 1.6. P2 has a 2.8 GHz clock rate and a CPI of 1.2. P3 has a 4.0 GHz clock rate and has<br>a CPI of 2.2.<br>a. Which processor has the highest performance expressed in instructions per second?<br>b. If the processors each execute a program in 9 seconds, find the number of cycles and the number of<br>instructions.<br>c. We are trying to reduce the execution time by 33°%, but this leads to an increase of 22% in the CPI. What<br>cłock rate should we have to get this time reduction?<br>
