Estimation of Maximum Speed-Up in Multicore-Based Mobile Devices

This letter proposes an effective speed-up estimation method for modern mobile devices. Unlike existing approaches, the proposed method uses a task graph to extract multiple parallelizable fractions of real-world mobile scenarios. Then, it uses the extracted parallelizable fractions to estimate the theoretical maximum speed-up of mobile devices. In experiments, the proposed method estimated the maximum speed-up of mobile devices more accurately than the state-of-the-art speed-up estimation method.
