Method and apparatus for memory management of video images

摘要

A novel storage format enabling a method for improved memory management of video images is described. The method includes receiving an image consisting of a plurality of color components. Once received, the plurality of color components is converted to a mixed format of planar format and packed format. The mixed packet format is implemented by storing one or more of the plurality of color components in a planar format and storing one or more of the plurality of color components in a packed format. A method for writing out video images is also described utilizing a write combining (WC) fame buffer. The decoding method motion compensates groups of macroblocks in order to eliminate partial writes from the WC frame buffer.
