1.6.3 [5] <1.4> A new compiler is developed that uses only 600 million instructions
and has an average CPI of 1.1. What is the speedup of using this new compiler
versus using Compiler A or B on the original processor of 1.6.1?
Consider two different implementations, P1 and P2, of the same instruction set.
There are five classes of instructions (A, B, C, D, and E) in the instruction set. P1
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 P1 and P2 are listed in the following table.
