ABSTRACT:
Provided is a system for compressing multiple-sample-anti-aliasing (MSAA) tile data in a computer graphics pipeline. The system includes a plurality of pixels configured as a tile, where the tile has a plurality of samples of descriptor data for the pixels. Multiple graphics data processing units configured to receive the plurality of samples contain a plurality of coverage masks, which correspond to covered subtiles and compression logic encodes the tile descriptor data for receipt by a buffer.
