Claim:
A method for decompressing a compressed texture data, said method comprising: receiving a compressed texture data; selecting a compressed texture block within said compressed texture data, wherein said compressed texture block comprises a luminance palette index, a chrominance palette index and a plurality of texel indices for a plurality of texels that formed said compressed texture block, wherein each of said texel indices corresponds to an index within a palette entry selected by said luminance palette index and said chrominance palette index; reading a luminance value of a selected texel from a stored luminance palette having a plurality of luminance palette entries using said luminance palette index and a corresponding portion of one of said plurality of texel indices; and reading a chrominance value of said selected texel from a stored and a chrominance palette having a plurality of chrominance palette entries using said chrominance palette index and a corresponding portion of one of said plurality of texel indices.
