The time-varying workload for multimedia applications poses a great challenge for the
efficient performance of dynamic voltage scaling (DVS) algorithms. While many DVS …

The H. 264/AVC video coding standard can deliver high compression efficiency at a cost of
increased complexity and power. The increasing popularity of video capture and playback …

We consider the problem of energy-efficient on-line scheduling for slice-parallel video
decoders on multicore systems with Dynamic Voltage Frequency Scaling (DVFS) enabled …

The past years have shown that due to the global success of video communication
technology, the corresponding hardware systems nowadays contribute significantly to …

Software realizations of computationally-demanding image processing tasks (eg, image
transforms and convolution) do not currently provide graceful degradation when their clock …

In our previous work, we proposed a systematic cross-layer framework for dynamic
multimedia systems, which allows each layer to make autonomous and foresighted …

In this paper we show that a small amount of bit stream features can be used to accurately
estimate the energy consumption of state-of-the-art software and hardware accelerated …

In this paper, we aim to bridge the gap between the energy efficiency of software and
hardware video decoders by combining both DVFS and parallelism. For this purpose, we …

Sub-50nm CMOS technologies are affected by significant variability, which causes power
and performance variations among nominally similar cores in MPSoC platforms. This …

We propose a general quality-power adaptation framework that controls the perceived video
quality and the length of viewing time on battery-powered video receivers. The framework …
