Question:

The following table shows the instruction type breakdown per processor of given applications executed in different numbers of processors.a. b. Processors 2 16 FP Instr. 280 x 106 50 x 10 INT Instr. 1000 x 16 110 x 10 L/S Instr. 640 x 106 80 x 106

Assume that each processor has a 2 GHz clock rate.

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 30%?
