1.14 Assume a program requires the execution of 50 x 106 FP instructions, 110 x 106 INT instructions, 80 x 106 L/S instructions, and 16 x 106 branch instructions. The 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? 1.14.2 [10] <$1.10> By how much must we improve the CPI of L/S instructions if we want the program to run two times faster?
