ABSTRACT:
A memory mapping method is provided for writing block data composed of a plurality of lines in first and second memories, each memory including at least two banks of the same number. The method maps the memories such that continuous even-numbered lines are written in different banks of different memories, and continuous odd-numbered lines are written in different banks of different memories when the block data is motion-compensated in a frame mode or a field mode. Accordingly, bank interleaving can be carried out in the respective memories and two memory channels can be simultaneously used to improve bus utilization efficiency and memory channel utilization efficiency.
