Speedup - Wikipedia

We are testing the effectiveness of a branch predictor on the execution of a program. First, we execute the program with the standard branch predictor on the processor, which yields an execution time of 2.25 seconds. Next, we execute the program with our modified (and hopefully improved) branch predictor on the same processor, which produces an execution time of 1.50 seconds. In both cases the execution workload is the same. Using our speedup formula, we know Witryna1 lut 2024 · What is the speedup of using this new compiler versus using compiler A or B on the original processor? Attempted Solution: a. Using the formula T = I ∗ C P I ∗ C C where C C = clock cycle time, I calculated part a of the question C P I A = T A I A ∗ C C A = 1.1 Similarly, C P I B = 1.25 b.
