Amdahl's Law: The Performance Improvement To Be Gained from Using Some Faster Mode of

EXECUTION is limited by the Fraction of the time the fat mode can be used

Execution Time Enhanced = Excution Time Unremined × Unremnive Proportion Excution Time Enhanced × has been enhanced ratio

Execution Time Reinforced = Excution Time Unhappy × [Uninforced Proportion (Reinforced Proportion / Speedup)

Therefore: spetedupoverall = Excution Time is not enhanced / Excution Time strengthens

= 1 / [(1- has been enhanced ratio) (enhanced proportion / speedup)]
