<p><P>PROBLEM TO BE SOLVED: To provide a method and apparatus for mapping memory, capable of simultaneously improving bus utilization efficiency and channel utilization efficiency. <P>SOLUTION: When block data is motion-compensated in a frame mode or a field mode, memories are mapped 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. Accordingly, bank interleaving can be carried out in the respective memories and two memory channels can be simultaneously used to improve the bus utilization efficiency and the memory channel utilization efficiency. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
