Assume a program requires the execution of 25 × 212 FP instructions, 220 x 53 INT instructions, 160 × 53 L/S instructions, and 32 x 53 branch instructions. The CPI for each type of instruction is 1, 1, 4, and 2, respectively. Assume that the processor has a 4 GHz clock rate. 1.1. Calculate the CPI of this program 1.2. By how much must we improve the CPI of L/S instructions if we want the program to run two times faster? (hint: Amdahl's Law) 1.3. By how much is the execution time of the program improved if the CPI of INT and FP instructions is reduced by 40% and the CPI of L/S and Branch is reduced by 50%?
