A coprocessor is added to a computer to speed the execution time of string?processing instructions by a factor of 3.5. What fraction of the execution time must these string?processing instructions use in order to achieve an average speedup of 1.5?
What will be an ideal response?
The new time to perform a task is f + (1 ? f)/3.5 where f is the fraction of time for which the speedup mechanism is not used. The speedup factor is the reciprocal of this value; that is, 1/( f + (1 ? f)/3.5) = 1.5 or 2 = 3(f + (1 ? f)/3.5). This gives f = 4/7.5 = 0.53. The string?processing hardware must be used for 53% of the time.
