MEMORY MAPPING APPARATUS AND METHOD FOR VIDEO DECOER/ENCODER

摘要

A memory mapping apparatus and method is provided for a video decoder/encoder. A dividing unit divides picture data into macroblocks and divides each of the macroblocks, which is a unit of encoding, into partitions having a predetermined size. A storage unit comprises at least one memory bank which is independently accessible. A memory allocation unit allocates adjacent partitions to different memory banks. Accordingly, it is possible to reduce a total number of cycles necessary to read and write the picture data.
