If the optimization resulted in the speedup of processing memory operations by a factor of 4, (a) what is the speedup of the optimization ? (b) what is the theoretical maximum speedup that could be achieved by optimizing floating point operations (if floating point operations took zero time)? 12nt y T T T-2 1 10 Suppose that a given machine spends 1/8 of its execution time before optimization doing floating point instructions.
