  • Method of and Apparatus for Compressing and Uncompressing Image Data
    Publication number: 20080131008
    Abstract: The present invention provides for a method of and apparatus for compressing and uncompressing image data. According to one embodiment of the present invention, the method of compressing a color cell comprises the steps of: defining at least four luminance levels of the color cell; generating a bitmask for the color cell, the bitmask having a plurality of entries each corresponding to a respective one of the pixels, each of the entries for storing data identifying one of the luminance levels associated with a corresponding one of the pixels; calculating a first average color of pixels associated with a first one of the luminance levels; calculating a second average color of pixels associated with a second one of the luminance levels; and storing the bitmask in association with the first average color and the second average color.
    Type: Application

  • Combined floating-point logic core and frame buffer
    Patent number: 6760033
    Abstract: A method and apparatus for graphical processing. A logic core to perform pixel fragment manipulation and processing is instantiated on a single substrate with one or more memory units. The memory units are dynamically segmentable into frame buffer and texture memory. Because the logic core is on the same substrate as the memory units, the bandwidth between the core and the memory is greatly increased.
