1.14 Another pitfall cited in Section 1.11 is expecting to improve the overall perform- ance of a computer by improving only one aspect of the computer. Consider a com- puter running a program that requires 250 s, with 70 s spent executing FP in- structions, 85 s executed L/S instructions, and 40 s spent executing branch instruc- tions. 1.14.1 [5] By how much is the total time reduced if the time for FP op- erations is reduced by 20%? 1.14.2 [5] By how much is the time for INT operations reduced if the total time is reduced by 20%? 1.14.3 [5] Can the total time can be reduced by 20% by reducing only the time for branch instructions
