    Abstract: 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.

    Abstract: Systems, apparatuses and methods may provide for associating a first instruction pointer with an IF block of a primary IF-ELSE conditional construct associated with a thread and activating a second instruction pointer in response to a dependency associated with the IF block. Additionally, the second instruction pointer may be associated with an ELSE block of the primary IF-ELSE conditional construct. In one example, the IF block and the ELSE block are executed, via the first instruction pointer and the second instruction pointer, one or more of independently from or parallel to one another.

    Abstract: Programmable predication logic in command streamer instruction execution is described. In one example, the invention includes a method that includes receiving batch buffer execution start command at a command streamer, the batch buffer containing executable instructions, determining whether predication has been enabled for the instructions using the start command, if predication has been enabled, then comparing a predication condition to values stored in a predication register, and if the condition is satisfied by the predication register values, then executing the batch buffer.
