论文摘要
电池寿命是移动设备使用的主要局限性之一，这使得对节能软件和硬件的研究成为重要的任务。本文研究了在移动平台上解码压缩的Bitstream视频时CPU所需的能量。得出了一个模型，该模型描述了用于内部编码视频的新型HEVC解码器的能耗。我们表明，模型的相对估计误差小于3.2％，并且该模型可用于构建旨在最小化解码能量的编码器。
Battery life is one of the major limitations to mobile device use, which makes research on energy efficient soft- and hardware an important task. This paper investigates the energy required by a CPU when decoding compressed bitstream videos on mobile platforms. A model is derived that describes the energy consumption of the new HEVC decoder for intra coded videos. We show that the relative estimation error of the model is smaller than 3.2% and that the model can be used to build encoders aiming at minimizing decoding energy.
