Assume a program requires the execution of 50 × 106 FP (Floating Point) instructions, 110 × 106 INT (integer) instructions, 80 × 106 L/S (Load/Store) instructions, and 16 × 106 branch instructions. The CPI for each type of instruction is 1, 1, 4, and 2, respectively. Assume that the processor has a 2GHz clock rate. Part A: By how much must we improve the CPI of FP (Floating Point) instructions if we want the program to run two times faster? Part B: By how much must we improve the CPI of L/S (Load/Store) instructions if we want the program to run two times faster? Part C: By how much is the execution time of the program improved if the CPI of INT (Integer) and FP (Floating Point) instructions are reduced by 40% and the CPI of L/S (Load/Store) and Branch is reduced by 30%?

Transcribed Image Text:Assume a program requires the execution of 50 × 106 FP (Floating Point) instructions, 110 × 106 INT
(integer) instructions, 80 × 106 L/S (Load/Store) instructions, and 16 × 106 branch instructions. The CPI
for each type of instruction is 1, 1, 4, and 2, respectively. Assume that the processor has a 2GHz clock
rate.
Part A: By how much must we improve the CPI of FP (Floating Point) instructions if we want the
program to run two times faster?
Part B: By how much must we improve the CPI of L/S (Load/Store) instructions if we want the program
to run two times faster?
Part C: By how much is the execution time of the program improved if the CPI of INT (Integer) and FP
(Floating Point) instructions are reduced by 40% and the CPI of L/S (Load/Store) and Branch is
reduced by 30%?
