Answer the following questions by clearly showing all your steps and using the

Amdahl's law formula discussed in the lecture slides.b$.$ Which section takes the least execution time and which section takes the most

execution time?

c$.$ By reducing the execution time of the arithmetic section, can the entire code gain

a speed$-$up of $2x?$ Use Amdahl's law to calculate the speed$-$up possibility.

d$.$ By reducing the execution time of the write back section, can the entire code gain

a speed$-$up of $3x?$ Use Amdahl's law to calculate the speed$-$up possibility.

e$.$ Which of the two sections' can be combined and their execution time can be

reduced so that the entire code can gain a speed$-$up of $4x?$ Use Amdahl's law to

calculate the speed$-$up possibility.
