Power Optimization for Mobile multimedia

ABSTRACT A mobile device is a very powerful to support increasing multimedia functions. To support these high computing and high bandwidth operations on a mobile device with limited energy, the power-aware design concept is expected to be introduced for further power optimization. A power-aware system is a design that can adaptively adjust its power consumption to specific conditions, such as different battery status, signal content, user preferences, and operating environments. In this paper, we focus on the introduction of power-aware concepts and considerations to the architecture design of a video coder, followed by discussions of exiting power aware Motion Estimation and Discrete Cosine Transform designs
