What are thepeak performances of P1 and P2 expressed in instructions persecond. b) If the number of instructions executed in a certain programis divided equally among the classes of instructions except forclass A, which occurs twice as often as each of the others. Whichcomputer is faster? How much faster is it? c) If the number of instructions executed in a certain programis divided equally among the classes of instructions except classE, which occurs twice as often as each of the others?
