    摘要: Systems and methods that decompress block compressed texture data may decompress the texture data while simplifying computations to reduce die area while maintaining the required accuracy. Reducing the die area permits more texture data to be decompressed in the same die area compared with a more accurate decompression, thereby increasing texture decompression throughput. Computations are simplified by combining denominators for linear interpolation with format conversion to decompress texture data components compressed using conventional block compression formats.
