  • Methods for compressing and decompressing texture tiles and apparatuses using the same
    Patent number: 11425403
    Abstract: The invention introduces a method for compressing texture tiles, which contains at least the following steps: lossless-compressing raw data of a texture tile; determining whether a length of the lossless-compression result of the raw data is greater than a target result; and when the length of the lossless-compression result of the raw data is greater than the target length, performing data-reduction control in layers for generating reduced data by reducing the raw data, and generating a lossless-compression result of the reduced data, thereby enabling the length of the lossless-compression result of the reduced data to be equal to the target length or shorter.
    Type: Grant

  • Methods for compressing and decompressing texture tiles and apparatuses using the same
    Patent number: 10074040
    Abstract: The invention introduces a method for compressing texture tiles, which contains at least the following steps: classifying each pixel of a texture tile into one of a plurality of groups and generating a bitmap of the texture tile, wherein the bitmap contains information indicating to which group each pixel of the texture tile belongs; reducing dependencies between pixels of each group; lossless-encoding each pixel of the texture tile to generate a first compression result; and outputting the first compression result and the bitmap.
