Problem 2: (9 pts, 3pts each sub-part) Assume a program requires the execution of 50 x 10 6 FP instructions, 110 x 10 6 INT instructions, 80 x 106 Load/Store (L/S) instructions and 16 x 10*6 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. faster? b) By how much must we improve the CPI of L/S instruction if we want the program to run two times faster? c) By how much is the execution time of the program improved if the CPI of INT and FP instructions are reduced by 40% and the CPI of LS and Branch is reduced by 30%? Clarification: you are asked to improve the CPI of one category of commands every time with the goal to make the WHOLE program run two times faster. You may find that one or more of these cases is impossible to implement, or you may be able to identify improvement for all the above cases. Solution
