ABSTRACT:
The invention is directed, in one embodiment, to a method for generating memory addresses for accessing an image in which each pixel in a group of pixels has a luma component, but shares chroma components with other pixels of the group. A preferred method includes providing a memory, having a plurality of first portions and a plurality of second portions. First memory addresses may be generated, each of which corresponds to one of the first portions. Each first address defines a storage location for the luma components of one of the pixel groups. Second memory addresses may be generated, each of which corresponds to one of the second portions. Each second address defines a storage location for the chroma components of at least one of the pixel groups.
