Original Abstract Submitted

A method of improving texture fetching by a texturing/shading unit in a GPU pipeline by performing efficient convolution operations, includes receiving a shader and determining whether the shader is a kernel shader. In response to receiving a kernel shader, the kernel shader is modified to perform a collective fetch of all texels for a group of output pixels instead of performing independent fetches of texels for each output pixel in the group of output pixels.
