Data Reuse method between Heterogeneous Partitions (DRHP) in H.264/AVC motion compensator

In H.264/AVC decoder system, motion compensator (MC) is the most critical component in terms of computational complexity and memory access. We propose Data Reuse method between Heterogeneous Partitions (DRHP) to reduce the memory access of MC. Our method reuses data in the overlapped region between memory access regions of neighboring blocks in the different partitions as well as in the same partition. DRHP reduces memory access especially well at high-quality video stream and, without additional buffers, achieves up to 20.4% less memory access compared to the conventional scheme.
