METHOD AND DEVICE OF PROCESSING VIDEO

摘要

A memory controller is disclosed that allocates local memory space to a set of macroblocks of a picture being processed. Information associated with a specific macroblock of the set of macroblocks is written to non-local memory when it is no longer needed to complete processing of a current row of macroblocks. When information associated with the specific macroblock is later needed to process a different row of macroblocks, the memory controller allocates local memory space to the specific macroblock and stores the previously saved information from non-local memory to the local memory.
