Suppose you have a program that runs in 100 seconds on

Suppose you have a program that runs in 100 seconds on a particular computer, and profiling of the execution time indicates that 25% is for multiplication, 50% is for memory access, and 25% for other instructions. ter. b. Suppose you change the program so that the execution time distribution is no longer 25%, 50%, and 25%. If none of the percentages can be zero, describe by formula or example what sort of program would result in no speedup for each these modifications. i. Make multiply instructions run four times faster i Make memory access instructions run two times faster.
