Applying texture cache approximation to an image blur kernel on an NVIDIA 780GTX, we obtain a 12% reduction in kernel execution time while only introducing 0.4% output error in the final image.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>We present texture cache approximation as a method for using existing hardware on GPUs to eliminate costly global memory accesses.
