Consider the following two processors. Pl has a clock rate of 3.2 GHz, average CPI of 0.85, and requires the execution of 4.0E9 instructions. P2 has a clock rate of 2.7 GHz, an average CPI of 0.6, and requires the execution of 1.0E9 instructions. a) Which computer has the better performance? b) Determine the number of instructions that P2 can execute in the same time that P1 needs to execute 1.0E9 instructions c) Use MIPS to compare the performance of two different processors.
