Abstract
A texture prefetching apparatus in a graphics processing system having a texture memory is disclosed, comprising a first FIFO memory, a second FIFO memory, a main rasterizer, an auxiliary rasterizer and a cache data memory. The cache data memory is coupled between the first FIFO memory and the texture memory. The main rasterizer converts destination coordinates of a first pixel in a primitive into a cache entry and a tag for a first integer texel according to texture coordinates and destination coordinates of multiple vertices of the primitive. The auxiliary rasterizer coupled to the second FIFO memory converts destination coordinates of N second pixels in the primitive into multiple cache entries, multiple tags and multiple memory addresses for multiple second integer texels according to the texture coordinates and the destination coordinates of the multiple vertices, where N is a multiple of 4.
