18 Claims

1. A computer system comprising one or more processors and a memory, the memory comprising computer readable instructions that, when executed by the one or more processors, cause the computer system to:

receive a shader;

determine whether the shader is a kernel shader; and

in response to determining that the shader is a kernel shader, modifying the shader to perform a collective fetch of all texels used in convolution operations for a group of output pixels instead of performing independent fetches of texels for each output pixel in the group of output pixels.
