FP = Floating-Point, INT = Integer, L/S = Load/Store 3. (4 pts) Another pitfall cited in Section 1.10 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 250 s, with 70 s spent executing FP instructions, 80 s spent executing INT instructions, 60 s spent executing L/S instructions, and 40 s spent executing branch instructions. a. By how much is the total time reduced if the time for FP operations is reduced by 20%? b. Can the total time be reduced by 20% by reducing only the time for branch instructions
