Q.5) A common pitfall is expecting to improve the overall performance of a computer by improving only one aspect of the computer. Consider a computer running a program that requires 280s, with 80s spent executing FP instructions, 90 s executing INT instructions, 60 s executing L/S instructions, and 50 s spent executing branch instructions. 5.a) By how much is the total time reduced if the time for FP operations is reduced by 20% ? 5.b) By how much is the time for INT operations reduced if the total time is reduced by 20%? 5.c) Can the total time can be reduced by 20% by reducing only the time for branch instructions
