    摘要: Systems and methods for texture processing are presented. In one embodiment a texture method includes creating a sparse texture residency translation map; performing a probe process utilizing the sparse texture residency translation map information to return a finest LOD that contains the texels for a texture lookup operation; and performing the texture lookup operation utilizing the finest LOD. In one exemplary implementation, the finest LOD is utilized as a minimum LOD clamp during the texture lookup operation. A finest LOD number indicates a minimum resident LOD and a sparse texture residency translation map includes one finest LOD number per tile of a sparse texture. The sparse texture residency translation can indicate a minimum resident LOD.

    摘要: One embodiment of the present invention sets forth a technique for reducing the overhead for transmitting explicit begin and explicit end commands that are needed in primitive draw command sequences. A draw method includes a header to specify an implicit begin command, an implicit end command, and instancing information for a primitive draw command sequence. The header is followed by a packet including one or more data words (dwords) that each specify a primitive topology, starting offset into a vertex or index buffer, and vertex or index count. Only a single clock cycle is consumed to transmit and process the header. The performance of graphics application programs that have many small batches of geometry (as is typical of many workstation applications) may be improved since the overhead of transmitting and processing the explicit begin and explicit end draw commands is reduced.

    摘要: A method and system for overriding state information programmed into a processor using an application programming interface (API) avoids introducing error conditions in the processor. An override monitor unit within the processor stores the programmed state for any setting that is overridden so that the programmed state can be restored when the error condition no longer exists. The override monitor unit overrides the programmed state by forcing the setting to a legal value that does not cause an error condition. The processor is able to continue operating without notifying a device driver that an error condition has occurred since the error condition is avoided.

    摘要: One embodiment of the present invention sets forth a technique for executing a software method within a graphics processing unit (GPU) that minimizes the number of clock cycles during which the graphics engine is idled. The function of the software method is performed by a firmware method that is executed by a processor within the GPU. The firmware method is executed to access and optionally update the state stored in the GPU. Unlike execution of a conventional software method, execution of the firmware method does not require an exchange of information between a CPU and the GPU. Therefore, the CPU is not interrupted and throughput of the CPU is not reduced.

    摘要: Method and apparatus for display image adjustment is described. More particularly, handles associated with polygon vertices of a polygon rendered image are provided as a graphical user interface (GUI). These handles may be selected and moved by a user with a cursor pointing device to adjust a displayed image for keystoning, among other types of distortion. This GUI allows a user to adjust a projected image for position of a projector with respect to imaging surface, as well as for imaging surface contour, where such contour may be at least substantially planar, cylindrical, or spherical and where such contour may comprise multiple imaging surfaces. This advantageously may be done without special optics or special equipment. An original image is used as texture for rendering polygons, where the image is applied to the rendered polygons.

    摘要: Systems and methods for synchronizing processing work performed by threads, cooperative thread arrays (CTAs), or “sets” of CTAs. A central processing unit can load launch commands for a first set of CTAs and a second set of CTAs in a pushbuffer, and specify a dependency of the second set upon completion of execution of the first set. A parallel or graphics processor (GPU) can autonomously execute the first set of CTAs and delay execution of the second set of CTAs until the first set of CTAs is complete. In some embodiments the GPU may determine that a third set of CTAs is not dependent upon the first set, and may launch the third set of CTAs while the second set of CTAs is delayed. In this manner, the GPU may execute launch commands out of order with respect to the order of the launch commands in the pushbuffer.
