I. Introduction
The Increasing demand for higher definition and faster frame rate video is making high-performance and low-power critical in hardware video decoders. Mobile multimedia devices such as smart phones are energy-constrained, so reducing their power is critical for extending video playback times. For wired devices such as set-top boxes, speed is critical for high-quality video playback. Ideally, a video decoder would not require a different architecture for these two types of applications. This would help reduce design time and lower implementation costs.
