Change 1.6.5 to read:

If the number of instructions executed in a certain program is divided equally among the classes of instructions found in Table 1.6.3a except for class A, which occurs twice as often as each of the others, how much faster is one processor to the other. Specifiy which processor is faster

There are five classes of instructions (A, B, C, D, and E) in the instruction set. P has a clock rate of 4 GHz, and P2 has a clock rate of 6 GHz. The average number of cycles for each instruction class for Pl and P2 are listed in the following tabl: Closs CPI on P2 Class cPI on P1 CPIon P2 b. 1.6.4 151 Assume that peak performance is deined as the fastest rate that a computer can execute any instruction sequence. Wha: are the peak performances of PI and P2 expressed in instructions per second? 1.6.5 [511.4> If the number of instructions executed in a certain program is divided equally among the classes of ins ructions in Prolem 2.364 except for dass A, which occurs twice as often as each o the cthers, how much faster is P2 than P1? 1.6.6 151 At what frequency does P2 have the same performance as Pl for the instruction mix given in 1.6.5
