Instruction Frequency Cycle
Load /Store 10% 2
Integer Add/Sub 15% 1
FP Add/sub 50% 5
FP Multiply/divide 5% 20
Others 5% 1
branches 15%

Overall Speed= (102)+(151)+(505)+(520)+(5*1)=20+15+250+100+5=390/100=3.9 cycle per instruction

CPU seconds = (Number of instructions * Number of Clocks per instructions)/Clock Rate

=29*3.9/2

=56.55 seconds

To make Enhancement more number of register and more number of processor has to be connected
