1.13. (30%) A 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, 85 s executed L/S instructions, and 40 s spent executing branch instructions (rest of the time on integer INT operations). 1.13.1 By how much is the total time reduced if the time for FP operations is reduced by 20%? 1.13.2 By how much is the time for INT operations reduced if the total time is reduced by 20%? 1.13.3 Can the total time can be reduced by 20% by reducing only the time for branch instructions
