Abstract
To encode a texture to be used in a graphics processing system, the texture is first downscaled to generate a lower resolution representation of the texture. An upscaled versionof the lower resolution version of the texture is then compared to the original texture to determine a set of difference values indicating for each texel the difference between the value of the texel in the upscaled version of the texture and in the original texture. An encoded texture data block is then generated for each 8×8 block of texels in the original texture. Each encoded texture data block contains a base color value taken from the lower resolution representation of the texture and a set of index values indicating the difference data from the determined set of difference data to be used when decoding the block of texture data to generate the data values to be used for the texture data elements that the block of texture data represents.
