US Patent 9912957 Lossless compression for multisample render targets alongside fragment compression

One embodiment provides for a general-purpose graphics processor comprising a multisample antialiasing compression module to examine a number of colors to be stored for a set of sample locations of a pixel and allocate one or more planes to store color data for the set of sample locations of the pixel and a lossless compression module to apply lossless compression on the one or more planes and update a compression status in a compression control surface for each of the one or more planes.
