This paper addresses the problem of how to efficiently manage the power consumption while preserving high visual quality performance in video coding for pervasive video applications. We define an optimization problem that corresponds to the minimization of both the power consumption and video distortion of a video encoder. A joint rate-complexity-distortion(R-C-D) model is developed to capture and...
Most compiler optimization techniques concern most about speed. In this paper, we present two high-level power/energy optimization methods for ARM-based battery-powered embedded multimedia systems, e.g. mobile phones, pocket PCs, personal multimedia systems, etc. The experiments using MPEG-4 simple profile level 0 (SP@L0) video decoder on ARM920T with two QCIF video sequences 15 fps, 24 kbps show...
