Question part B would be great to know for sure.

The following table shows the execution time of five routines/fractions that compose an overall program. Routine A (s Routine B (s) Routine C (s) Routine D (s) Routine E (s) 210 60 10 901 (a) Assume that a micro-architectural change helped to reduce the execution time of routine D by 40%. Using Amdahl's Law calculate the achieved overall speedup and the new total execution time of the overall programme. [3 pointsl (b) You were asked to apply a micro-architectural change that can speedup either i) routine B by 20% or ii) routine A by 30%. Explain which option will you choose to speedup and using Amdahl's Law calculate the speedup and new execution time of the overall programme that you will get in both cases. [5 points]
