摘要: H.264/AVC outperforms previous video coding with many other tools, but the complexity increases much. As image resolution is high, bus bandwidth and data read cycle are most important problems for real time processing decoder. Motion compensation main bottleneck, which can use about over 50% of total bandwidth. In this paper, we present a aware motion (BAMC) solve both in various systems. BAMC saves 60-80% MC 50-85% at system DDR1-32bit or DDR2-64 bit. The proposed hardware supports 1088-60 p real-time less than 266 MB/S memory
