Another pitfall cited in COD Section 1.10 (Fallacies and pitfalls) 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, 85 s executed L/S instructions, and 40 s spent executing branch instructions. 1.13.1 [5] By how much is the total time reduced if the time for FP operations is reduced by 20%? 1.13.2 [5] By how much is the time for INT operations reduced if the total time is reduced by 20%? 1.13.3 [5] Can the total time can be reduced by 20% by reducing only the time for branch instructions?
