Question 9(20 points)
Saved
Consider three different processors P1, P2, and P3 executing the same instruction set. P1 has a 3.00 GHz clock rate and a CPI of 1.5. P2 has a 2.50 GHz clock rate and a CPI of 1.0. P3 has a 4.00 GHz clock rate and has a CPI of 2.2.
a. Find execution time for each processor {The first three answer boxes in order of processor number, only write the rounded (up) time in seconds in format of d.d; e.g.0.7} for a program with 2.00e+9(2e+09 is a notation for 2x(10^9)=2,000,000,000) instructions. Which one is the fastest {The fourth answer box just the number of fastest processor, 1,2, or 3}?
b. If the processors each execute a program in 10 seconds, find the number of instructions that they are running {The answer boxes 5,6, and 7 for processor 1,2, and 3 respectively, in the format of d.dde+dd; e.g.1.79e+10}? We are trying to reduce the execution time by 20% but this leads to an increase of 10% in the CPI. What clock rate in GHz should we have to get for this time reduction for each processor {The last three answer boxes in order of processor numbers in format of d.d; e.g.3.1}?
