Jonathan J. Dunaisky has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Method and apparatus for obtaining sampled positions of texturing operations
    Patent number: 10699427
    Abstract: Methods and apparatuses are disclosed for reporting texture footprint information. A texture footprint identifies the portion of a texture that will be utilized in rendering a pixel in a scene. The disclosed methods and apparatuses advantageously improve system efficiency in decoupled shading systems by first identifying which texels in a given texture map are needed for subsequently rendering a scene. Therefore, the number of texels that are generated and stored may be reduced to include the identified texels. Texels that are not identified need not be rendered and/or stored.

  • System, method, and computer program product for validating a graphics processor design
    Patent number: 8063908
    Abstract: A system, method, and computer program product are provided for validating a graphics processor design. In operation, a test image is identified. Additionally, a reference image is automatically selected from a set of reference images. Furthermore, a graphics processor design is validated using the test image and the selected reference image.

  • Blend optimizations that are conformant to floating-point rules
    Patent number: 7880747
    Abstract: A technique for handling floating-point special values, e.g., Infinity, NaN, ?Zero, and denorms, during blend operations is provided so that blend operations on fragment color values that contain special values can be performed in compliance with special value handling rules. In particular, the presence of special values is detected or the potential presence of special values is detected. This information is used to qualify when blend optimizations may be performed, so that floating point blend operations can remain conformant to special value handling rules.
