摘要

HEVC doubles the coding efficiency with more than 4x coding complexity as compared to H.264/AVC. To alleviate the burden of Intra encoder, we estimate the RD-cost from the source image textures, and dynamically select two promising CU/PU mode candidates to execute exhaustive RDO processing. As integrated in our hardwired encoder, the averaged 61.7% computation complexity was saved with 4.53% rate augment. With TSMC 90nm technology, the real-time encoder for HDTV1080p at 44fps is implemented with 2269k-gate at 357MHz operating frequency.
