Abstract

A fragment shader program to be executed by a fragment shader of a graphics processor can include a graphics texturing instruction that when executed by the fragment shader will cause the fragment shader to send a request to the texture mapper to perform a graphics texture mapping operation in which the texture mapper will perform plural lookups from the same texture in parallel. In response to the request from the fragment shader, the texture mapper of the graphics processor performs plural lookups from the same texture in parallel, and generates a texture mapping operation result using the results of the plural lookups from the same texture for returning to the fragment shader.
