ABSTRACT:
A method and apparatus for decompression of a two dimensional video texture map such that an object may subsequently be displayed as a three dimensional object is generally accomplished by a set-up engine which receives vertex parameters and generates a plurality of derivatives and Bresenham parameters, therefrom. The derivatives and Bresenham parameters are provided to an edgewalker circuit which produces, therefrom, a plurality of spans which, in turn, is converted in to a set of texel addresses by a texel address generator. A texel fetch circuit receives the set of texel addresses and uses the addresses to retrieve a set of texels, which is subsequently processed by a texel processor to produce a filtered pixel. To retrieve the set of texels, the texel fetch circuit retrieves a set of indexes based on the texel addresses and uses the set of texels to retrieve the set of texels from a codebook. The retrieval of the set of indexes and the indexing of the codebook is executed within two consecutive clock cycles.
