Bandwidth-Efficient Architecture Design for Motion Compensation in H.264/AVC Decoder
In this work, a Block-Clustering Based (BCB) method is proposed to reduce the memory access number of Motion Compensation (MC) in H.264/AVC Decoder. By grouping the possible 4x4 blocks within one Macroblock (MB) to share the loaded reference data, the memory access number can be significantly reduced around 70% in average. Moreover, to reduce the precharge/active frequency during SDRAM accessing, a command-reordering method is adopted to achieve 60% reduction in average. In our simulation, the total memory access number for processing one MB is less than 400 cycles. This method is scalable to different internal memory size used in MC hardware design.
