An Efficient Hardware Design for Intra-prediction in H.264/AVC Decoder
The H.264/AVC intra-frame codec is widely used to compress image/video data for applications like Digital Still Camera (DSC), Digital Video Camera (DVC), television studio broadcast, and surveillance video. Intra-prediction is one of the top 3 compute-intensive processing functions in the H.264/AVC baseline decoder and, therefore, consumes significant number of compute cycles a processor. In this paper, the authors propose a configurable, high-throughput, and area-efficient hardware design for the intra-prediction unit. The intra-prediction algorithm is optimized to significantly reduce the redundancy in addition operations (e.g., 27% reduction when compared with state-of-the-art in literature).
