Performance for entire task using the enhancement when possible
Speedup = -----------------------------------------------------------------
Performance for entire taks without using the enhancementSee SpeedUp
Notice that we are talking about the entire task here and that performance (speedup) is defined in terms of execution time! So we have to define the following:
Old Execution Time
SpeedupOverall = --------------------
New Execution Time
FractionEnhanced
New Execution Time = Old Execution Time ( (1 - FractionEnhanced) + ------------------ )
SpeedupEnhanced
-->
1
SpeedupOverall = --------------------------------------------
FractionEnhanced
(1 - FractionEnhanced) + ------------------ )
