Application of Amdahl's Law

What is the overall speedup if you make 15% of a program 85 times faster? What is the overall speedup if you make 85% of a program 15 times faster Question 2 Consider a dynamic RAM that must be given a refresh cycle 64 times per ms. Each refresh operation requires 150 ns; a memory cycle requires 250 ns. What percentage of the memory’s total operating time must be given to refreshes? Explain your answer and show your calculations. Question 3 List and briefly define three newer nonvolatile solid-state memory technologies. Question 4 What is the difference between DRAM and SRAM in terms of application? What is the difference between DRAM and SRAM in terms of characteristics such as speed, size, and cost?
