Energy-aware feedback control for a H.264 video decoder

Energy and Computing Ressource Aware Feedback Control Strategies for H.264 Video Decoding

Embedded devices using highly integrated chips must cope with conflicting constraints, while executing computationally demanding applications under limited energy storage. Automatic control and feedback loops appear to be an effective solution to simultaneously accommodate for performance uncertainties due to the tiny scale gates variability, varying and poorly predictable computing demands and...

Enhanced Energy-Aware Feedback Scheduling of Embedded Control Systems

Dynamic voltage scaling (DVS) is one of the most effective techniques for reducing energy consumption in embedded and real-time systems. However, traditional DVS algorithms have inherent limitations on their capability in energy saving since they rarely take into account the actual application requirements and often exploit fixed timing constraints of real-time tasks. Taking advantage of applic...

Energy-Aware Wireless Video Streaming

This paper presents a dynamic energy management policy for a wireless video streaming system, consisting of battery-powered client and server. The paper starts from the observation that the video quality in wireless streaming is a function of three factors: encoding aptitude of the server, decoding aptitude of the client, and the wireless channel. Based on this observation, the energy consumpti...

A Hardware Entropy Decoder for Scalable Video

In the RESUME project (Reconfigurable Embedded Systems for Use in Multimedia Environments) we explore the benefits of an implementation of scalable multimedia applications using reconfigurable hardware by building an FPGA implementation of a scalable wavelet-based video decoder. In this article we present the results of our investigation into the hardware implementation of such a scalable video...
