Abstract

This study examines the practical effectiveness of power strategies for video applications. Based on real implementations of three power strategies using representative platforms and H.264 applications, we analyse platform and application level parameters affecting the operability and efficiency of power strategies. Results show that, in the same conditions, a strategy might offer highly variable results and sometimes increases energy, depending on the characteristics of the platform. Therefore, we report different measurement results which lead to useful guidelines for succesful power management and show the potential benefits of advanced power strategies over currently available approaches for demanding workloads like video applications.
