Abstract
A programmable graphics processor including an execution pipeline and a texture unit is described. The execution pipeline processes graphics data as specified by a fragment program. The fragment program may include one or more opcodes. The texture unit includes one or more sub-units which execute the opcodes to perform specific operations such as an LOD computation, generation of sample locations used to read texture map data, and address computation based on the sample locations.
