摘要: In this paper we propose a low-bandwidth two-level inter-frame/ inter-view cache architecture for a view scalable multi-view video decoder, which adopts two decoder cores to decode multi-view videos in parallel. The first level L1 cache is developed for the single video decoder core, which is able to reduce 60% bandwidth in doing inter-frame prediction in average. Moreover, we develop the second level L2 cache architecture to reuse the same reference data for doing interview prediction among different decoder cores, which can further reduce 35% bandwidth. By adopting the proposed two-level cache architecture for doing inter-frame/ inter-view prediction, we can reduce 80% bandwidth through a view scalable multi-view video decoder implementation, which achieves real-time HD1080 dual-view video decoding.
