Suppose a program consists of 40% floating point multiply instructions, 30% floating point divide instructions, and the remaining 30% are other instructions. In the latest processor manufactured by your company, floating point division has a CPI of 4, floating point multiplication a CPI of 3, and each of the other instructions have the same CPI of 1. a) [12 points] What speedup would be achieved if floating point division were made 2 times as fast? Apply Amdahl's Law and justify your conclusion precisely. b) [12 points] What speedup would be achieved if floating point multiplication were made 3 times as fast? Again, use Amdahl's Law and justify your conclusion precisely.
