An energy optimization method for vector processing mechanisms
In order to achieve a low energy execution for any multimedia applications (MMAs) on a vector processing mechanism (VPM), the number of parallel arithmetic pipelines and the number of cache ports of VPM must be properly configured for each MMAs. Therefore, this paper proposes an energy optimization method for VPMs (EOM-VP), which finds the lowest energy configuration by using the greedy searching method and an analytical model. As the evaluation results suggest, EOM-VP could find the lowest or the second lowest energy configuration for all the benchmark programs in the evaluation.
