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)
