Consider a computer running a program that requires 350 s, with 65 s spent executing FP instructions, 75 s executing INT instructions, 190 s executed L/S instructions, and 20 s spent executing branch instructions a) By how much is the total time reduced if th other instruction classes remains unchanged? e time for FP operations is reduced by 40% and the timings for all the By how much is the time for LS instructions reduced if the total time is reduced by 30% and the timings for all the other instruction classes remains unchanged? It is assumed that the processor is modified to include vector registers and a vectorizing compiler is used to compile the program, which eliminates the need for the branches. If all the other instruction times are also reduced by 10%, what is the new execution time and what is the percent improvement? c)
