  • Texture caching arrangement for a computer graphics accelerator
    Patent number: 8018467
    Abstract: A method and apparatus which includes a graphics accelerator, circuitry responsive to pixel texture coordinates to select texels and generate therefrom a texture value for any pixel the color of which is to be modified by a texture, a cache to hold texels for use by the circuitry to generate texture value for any pixel, a stage for buffering the acquisition of texel data, and control circuitry for controlling the acquisition of texture data, storing the texture data in the cache, and furnishing the texture data for blending with pixel data.
    Type: Grant

  • Graphics pipeline selectively providing multiple pixels or multiple textures
    Patent number: 6628290
    Abstract: A method and graphics accelerator apparatus for pipelined generation of output values for a sequence of pixels, with generation of output values for each of at least two textured pixels during each pipeline clock interval. The apparatus includes a combiner stage capable of producing output values during each clock interval of the pipeline, wherein the output values are indicative of a blend of a plurality of textures with a single pixel when the combiner stage operates in a first mode, and the output values are indicative of a blend of an individual texture with two pixels when the combiner stage operates in a second mode.
