Question: Another common performance Figure is MFLOPS (million of floating-point operations per second), defined as MFLOPS = No. FP operations / (execution time 106) but

Another common performance Figure is MFLOPS (million of floating-point operations per second), defined as MFLOPS = No. FP operations / (execution time × 106) but this figure has the same problems as MIPS. Consider the program in the following table, running on the two processors below. a. b. Processor Instr. Count L/S FP P1 P2 P1 P2 No. Instructions CPI Branch L/S FP Branch 1.00E+06 50% 40%

Find the performance for the programs and compare it with MIPS and MFLOPS.

a. b. Processor Instr. Count L/S FP P1 P2 P1 P2 No. Instructions CPI Branch L/S FP Branch 1.00E+06 50% 40% 10% 0.75 1.0 1.5 5.00E+06 40% 40% 20% 1.25 0.8 5.00E+06 30% 30% 40% 1.5 1.0 2.00E+06 40% 30% 30% 1.25 1.0 1.25 2.0 2.5 Clock Rate 4 GHz 3 GHz 4 GHz 3 GHz
