2. The table below shows the execution time in percentage for various sections of a code. Answer the following questions clearly showing all your steps. | Time spent(%) 10% 15% 60% 20% 5% Section Initial File copy Write back Final a. Which section takes the least execution time and which section takes the most b. By reducing the execution time of the write back section can the entire code gain a c. By reducing the execution time of the computation section can the entire code gain d. Which of the two sections' execution time can be reduced so that the entire code execution time? (2 Points) speed-up of 2? (4 Points) a speed-up of 2 (4 Points) can gain a speed-up of 3? (5 Points)

Explanation / Answer

a)Least execution time = Final section (5%)

Most execution time = Computation (50%)

B) No

Time 100-----à80

Speed up 20/80*100=25%

Speed up 100-------à125

Speed up not 2 times

c) Yes

Time 100-----à50

Speed up 50/50*100=100%

Speed up 100-------à200

Speed up 2 times

D) Computation and write back

Time 100-------à30

Speed Up 70/30*100=233.33%

Speed Up 100--------à333.33

Speed Up more then 3 times

If we take (50+15) 65

Then time 100------à35

Speed Up 65/35*100=185.7%

Speed Up 100-------à285.7

Speed Up not 3 times
