Abstract:
The device and method described in this application relate generally to graphics processing systems utilizing the tile based rendering technique and more specifically relate to the processing of the framebuffer data in graphics processing applications. The present invention discloses techniques to reduce the bandwidth needed to access the color data stored in the framebuffer. A method for adaptive lossy delta based compression of color data is disclosed. The error rate, that is the amount of color data lost during the lossy compression process, is controlled by various parameters of the rendered tiles produced by the graphics processing system. The compression process is driven by a dedicated unit which enables informed compression decisions with controllable error rate so as the output color data can be reliably decompressed to produce the original color data with minimal or no errors.

Claim (Index 21):
A graphics processing unit (GPU) configured to perform adaptive framebuffer compression with controllable error rate, the GPU comprising:\n a tile renderer, communicatively coupled with a first memory, the tile renderer generating one or more tiles, each tile comprising a plurality of pixels, grouped into color channels; the first memory storing therein at least a first tile and a consecutive tile, such that the first tile is consecutive to the second tile or vice versa, wherein the first memory is further communicatively coupled with a sampling circuit; the sampling circuit configured to generate a sample from a tile by comparing at least a pixel of the tile, and another pixel of the tile; and a compression circuit configured to determine, for each color channel, a compression scheme based on the per channel sample, and a threshold defining an input error; wherein the compression scheme is configurable by one or more compression parameters, such that a degree of compression is at least one of: no compression, a lossless compression, and at least a first lossy compression, wherein different parameters are determined by the compression circuit for each color channel of the image data.
