Local macroblock information buffer

摘要

According to some embodiments, an external memory unit stores rows of macroblocks representing an image. A set of macroblocks may be transferred from the external memory unit to a local buffer, the set of macroblocks including fewer macroblocks than a row. A macroblock may then be decoded based on information in the local buffer to generate an image signal.

1. A method, comprising:
storing, in an external memory unit, rows of macroblock information representing an image; transferring information associated with a set of macroblocks from the external memory unit to a local circular buffer, the set of macroblocks having fewer macroblocks than a row and including (i) a current macroblock to be decoded, (ii) neighboring macroblocks to be used to decode the current macroblock, and (iii) non-neighboring macroblocks associated with a subsequent macroblock to be decoded after the current macroblock; and decoding a macroblock based on information in the local circular buffer to generate an image signal, wherein said decoding is based on information associated with the macroblock being decoded and information associated with at least one neighboring macroblock.
