ABSTRACT:
A texture unit of a graphics processing unit provides the ability to switch among different filter modes depending upon shader program instructions that are received by the texture unit. One filter mode has the capability to extract filter weights that have been specified in a received shader program instruction rather than calculating the weights within the texture unit itself.
