Abstract :
Multimedia applications for mobile devices, such as video/audio streaming, process streams of incoming data in a regular, predictable way. Content-aware optimizations through annotations allow us to highly improve the power savings at the various levels of abstraction: hardware/OS, network, application. However, in a typical system there is a continuous interaction between the components of the system at all levels, which requires a careful analysis of the combined effect of the aforementioned techniques. We investigate such an interaction and we describe metrics for estimating the effect various trade-off have on power and quality. By applying our metrics at the various abstraction levels we show how better energy savings can be achieved with lower quality degradations, through power-quality trade-offs and cross-layer interaction.
