ABSTRACT:
A graphics memory apparatus and methods for the organization, storage and playback of graphics data for display purposes. The image data and overlay data (and/or other graphics data) are organized and stored in the graphics memory in an interleaved fashion so that only one type of graphics data is stored at any one memory address (pixel data or overlay data or other graphics data) and so that preferably full memory capacity is utilized for the area of graphics memory employed. As an example, in a system for displaying eight bits of color image data and two bits of overlay, the overlay data is interleaved with the image data so that four consecutive address locations will contain image data, with preceding or following address location containing the associated overlay data. Therefore, such organization can result in graphics memory efficiency, reduced bandwidth requirements therefor and increased speed with which the contents or portions thereof may be loaded, altered, etc. Apparatus and methods for practicing the invention are disclosed.
