A pitfall cited in section 1.10 of the text book is expecting improve the overall performance of a computer by improving only one aspect of the computer. Consider a computer running a program that requires 200s, with 50s spent executing FP instructions, 65s executed Load/Store instructions, and 40s spent executing branch instructions, and the rest time for INT instructions. a) By how much (percentage) is the total time reduced if the time for FP operations is reduced by 20%? b) By how much (percentage) should the time for INT operations be reduced in order to reduce the total time by 10%? c) Can the total time be reduced by 25% by reducing only the time for branch instructions? Why?
