摘要：
In this paper, the low power design techniques from algorithm to architecture levels are proposed for factional motion estimation in H.264/AVC. The proposed AMPD algorithm can reduce 50.8% power with up to 0.1 dB quality drop. The proposed parallel architecture with efficient memory hierarchy can efficiently reuse data and save 61.6% power. Furthermore, the power aware functionality is included. Our design can gracefully vary the quality degradation of 0.1-3.9 dB in response to the 22.58-1.64 mW power consumption. This power-oriented design is very efficient for different mobile applications in various power situations.
