1.1 (10 points) Amdahl's Law (5 points) Consider a workload where 50% of the execution time consists of multimedia processing for which the MMX instruction set extensions might be helpful. According to Amdahl's law, what is the maximum speedup that can be achieved by implementing them? a. b. (5 points) Now, say that you work at Intel and the MMX designers claim that multimedia code sequences will see a 3.5 times (3.5X) speedup by using the MMX extensions. What is the fraction of the execution time that must be multimedia code in order to achieve an overall speedup of 1.8X
