Abstract:
Techniques are disclosed relating to a cache configured to store state information for texture mapping. In one embodiment, a texture state cache includes a plurality of entries configured to store state information relating to one or more stored textures. In this embodiment, the texture state cache also includes texture processing circuitry configured to retrieve state information for one of the stored textures from one of the entries in the texture state cache and determine pixel attributes based on the texture and the retrieved state information. The state information may include texture state information and sampler state information, in some embodiments. The texture state cache may allow for reduced rending times and power consumption, in some embodiments.
