Assume a program requires the execution of 50 × 106 fp instructions, 110 × 106 int instructions, 80 × 106 l/s instructions, and 16 × 106 branch instructions. th e cpi for each type of instruction is 1, 1, 4, and 2, respectively. assume that the processor has a 2 ghz clock rate. 1.14.1 [10] < §1.10> by how much must we improve the cpi of fp instructions if we want the program to run two times faster?
