摘要： A method, graphics processing unit, and system are described herein. The method for adaptive anisotropic filtering includes calculating a number of ways of anisotropy based on a computed level of detail of a texture map and applying a bilinear low pass filter to a texture map's closest two MIP maps using a processor. An effective number of ways and filter sizes may be computed on each of the closest two closest MIP maps. Additionally, the closest two MIP maps may be sampled at their respective effective number of ways. The method also includes applying a corresponding sized low pass filters to each of the closest two MIP maps, and combining the filtered closest two MIP maps using a weighted sum based on a fractional part of a computed level of detail.

摘要： Dynamic routing of texture-load in graphics processing is described. An example of a processor includes one or more processing resources, the one or more processing resources to load a message including a texture load; a texture sampler and a data port; and a message router to route the texture load to a destination, wherein the destination may be either the texture sampler or the data port; wherein the message router includes arbitration circuitry to select the destination for the texture load, the arbitration circuitry to base selection of the destination at least in part on support by the data port for a format of a memory surface for the texture load; and a utilization metric for the data port representing availability of the data port.
