Question

2. (25 Points) Consider a computer running a program 250 seconds, with 70 seconds spent executing FP instructions, 85 seconds Load/Store instructions, 55 seconds integer instructions, and 40 seconds spent executing branch instructions. a) By how much is the total time reduced if the time for FP instructions is reduced by 20%? b) By how much is the time for integer instructions only must be reduced if the total time (250 seconds) is reduced by 20%? c) Can the total time (250 seconds) be reduced by 20% by reducing only the time for branch instruction? Justify your answer.

Step 1

Current time spent on branch instructions: 85 seconds 20% reduction of 85 seconds: 85 * 0.2 = 17 seconds If we reduce the time for branch instructions by 20%, the new time spent on branch instructions would be 85 - 17 = 68 seconds. Now, let's calculate the new Show more…

Thanks for your feedback!

Justify your answer. Is the total time reduced by 20%? (25 points) Can the total time (250 seconds) be reduced by 20% by reducing only the time for branch instructions? b) By how much must the time for integer instructions only be reduced if the total time (250 seconds) is reduced by 20%? By how much is the total time reduced if the time for FP instructions is reduced by 20%? Load/Store instructions take 55 seconds, integer instructions take 40 seconds, and branch instructions take 85 seconds. Consider a computer running a program for 250 seconds, with 70 seconds spent executing FP instructions.
