In traditional four-stage pipeline structures for H.264 video encoder hardware implementation, rate distortion optimization (RDO) based mode decision was turned off, and dual-port or ping-pang on-chip search window SRAM was used to achieve data reuse between the integer and fractional pixel motion estimation. To support RDO based mode decision for efficient high definition AVS video coding implementation,...
In AVS video coding standard, some algorithms consume huge computation with relatively little coding performance contribution, and some algorithms create data dependencies that are harmful for efficient hardware pipeline. This paper focuses on hardware oriented algorithm analysis and modification. Motion estimation and mode decision algorithms are reviewed and modified to a hardware friendly configuration...
