Techniques to request stored data from a memory

摘要

Techniques are described to configure a cache line structure based on attributes of a draw call and access direction of a texture. Attributes of textures (e.g., texture format and filter type), samplers, and shaders used by the draw call can be considered to determine the line size of a cache. Access direction can be considered to reduce the number of lines that are used to store texels required by a sample request.

1. A computer-implemented method comprising:
determining a cache line size for a texture associated with a draw call based in part on a texture format attribute and texture filter type of a dominant texture; selecting a tag from a group of one or more ways in a texture cache to compare to a received tag; and in response to a tag match, providing data contents from one or more ways associated with the tag match based in part on the determined cache line size.
