Abstract
Embedded systems have moved recently towards multiprocessor architectures to support the level of performance required by new mobile applications. For those systems, power is a sensitive aspect that points to the need for study and developement of efficient power management strategies. This paper presents a concrete case study in one of the primarily concerned application domain: multimedia and video broadcasting. It reports the implementation details of a H.264/AVC decoder on a multiprocessor platform (ARM11 MPCore EB) considering in particular the problem of power reduction using online and offline techniques ofpower management (DVFS, DPM).
