METHOD FOR MAPPING IMAGE ADDRESSES IN MEMORY |
摘要 |
The invention discloses a method for mapping picture addresses in a memory, such that decoded picture data can be mapped in corresponding address in a memory. The memory comprises at least two memory arrays, each of which comprises multiple memory rows. The mapping method comprises the following steps: dividing one picture frame into multiple rectangle macroblocks; providing a memory for storing picture data and setting integral neighbor macroblocks of an picture frame as one mapping unit; one by one, the mapping units of picture data are consecutively mapped into the memory in the order of left to right in horizontal directions and up to down in vertical directions; mapping at least one mapping unit of picture data into the same memory row of the same memory array until the said memory row is full; switching the memory array and mapping the adjacent next mapping unit of picture data. The above steps are repeated until completing the mapping of one picture frame. |
