Embodiment Construction

[0029]The invention will be better understood from the following descriptions of various “embodiments” of the invention. Thus, specific “embodiments” are views of the invention, but each is not the whole invention. The present invention relates to a multiple instance shader engine filtering system wherein where each shader engine comprises multiple rows of shader engine filters combined with level one and level two cache systems. Each unified shader engine filter row accepts texture requests for a specified pixel from a resource and performs rendering and texture calculations, outputting texel data. In embodiments of this invention, bilinear texture filtering, trilinear texture filtering, and anisotropic texture mapping are applied to texel data stored in a multi level cache system. In another embodiment, a redundant shader system can be added and configured to each unified shader engine filter row to effectively repair defective shader pipes within the shader pipe array of the same...

Abstract

Apparatus and systems utilizing multiple shader engines where each shader engine comprises multiple rows of shader engine filters combined with level one and level two cache systems. Each unified shader engine filter comprises a shader pipe array, and a texture mapping unit with access to a level one cache system and a level two cache. The shader pipe array accepts texture requests for a specified pixel from a resource and performs associated rendering calculations, outputting texel data. The texture mapping unit retrieves texel data stored in a level one cache system, with the ability to read and write to and from a level two cache system, and through formatting and bilinear filtering interpolations generates a formatted bilinear result based on the specific pixel's neighboring texels. Utilizing multiple rows of shader engine filters within a shader engine allows for the parallel processing of multiple simultaneous resource requests. Utilizing multiple shader engines allows for greater processing through the use of multiple simultaneous processing. A method utilizing multiple shader engines to perform texture mapping is also presented.
