Abstract
Methods and systems for data compression and decompression in a graphics processing system are provided. For example, in at least one embodiment, a method comprises distributing the graphics data values of a pixel block about zero to minimize redundancy, and the pixel block includes a plurality of quadrants. The method further comprises determining whether to encode the distributed graphics data values, and responsive to a determination to encode the distributed graphics data values, encoding at least one graphics data value of one of the quadrants depending on an encoding indicator. The encoding includes determining an entropy parameter and dividing each positive data value by the entropy parameter yielding an entropy part and a noise part.
