Abstract
One embodiment of the present invention sets forth a method for compressing via a pixel shader color information associated with a line of pixels. An intermediary representation of an uncompressed stream of color information is first generated that indicates, for each pixel, whether a previous adjacent pixel shares color information with the pixel. A set of cascading buffers is then generated based on intermediary representation, where each cascading buffer represents a number of unique color codes across different groups of pixels. Finally, a compressed output stream that specifies the unique color codes as well as the number of pixels that share each unique color code is generated based on the set of cascading buffers.
