(c) (6 points) Consider two processors P1 and P2 executing the same instruction set. Pl has clock rate of 3 GHz and a CPI of 1.2. P2 has a clock rate of 3.8 GHz and a CPI of 2.0. i. (4 points) If the number of instructions for a program on P1 are 25E9, and for P2 are 19E9, then find the number of cycles and CPU time for P1 and P2 (2 points) To reduce the execution time by 30%, a reduction of 10% takes place in CPI. What clock rate will give this reduction
