MEMORY MAPPING APPARATUS AND METHOD IN VIDEO DECODER/ENCODER

PROBLEM TO BE SOLVED: To provide a memory mapping apparatus and method in a video decoder/encoder in which an independently accessible memory bank structure is utilized to decrease a total cycle number required for recording video data on a memory or for reproducing video data from the memory. SOLUTION: A memory mapping apparatus in a video decoder/encoder comprises: a dividing unit 1100 for dividing picture data into macroblocks and dividing each of the macroblocks into partitions having a predetermined size, the macroblock being a unit of encoding; a storage unit 1120 comprising at least more than one memory bank, each of the memory banks being independently accessible; and a memory allocation unit 1110 for allocating adjacent partitions among said partitions to different memory banks among said memory banks.
