Abstract
A display controller for a computer or the like stored display data in a tiled format in a display memory. Tile shape may be dynamically altered depending upon display mode (resolution, pixel depth, or the like) or other display factors. Tile shape (height versus width) may be optimized for different types of display (e.g., video, text, graphics, or the like). A display memory address conversion apparatus may receive pixel position data (e.g., from a BIT BLT engine or the like) and tile shape data and convert pixel position data to a tiled display memory address.
