    摘要: One embodiment of the present invention sets forth a technique to perform fine-grained rendering predication using an IGPU and a DGPU. A graphics driver divides a 3D object into batches of triangles. The IGPU processes each batch of triangles through a modified rendering pipeline to determine if the batch is culled. The IGPU writes bits into a bitstream corresponding to the visibility of the batches. The DGPU reads bits from the bitstream and performs full-blown rendering, including shading, but only on the batches of triangles whose bit indicates that the batch is visible. Advantageously, this approach to rendering predication provides fine-grained culling without adding unnecessary overhead, thereby optimizing both hardware resources and performance.

    摘要: A system and method uses the capabilities of a geometry shader unit within the multi-threaded graphics processor to offload data compression computations from a central processing unit (CPU), reduce the memory needed to store image data, and reduce the bandwidth needed to transfer image data between graphics processors and between a graphics processor and a system memory. The multi-threaded graphics processor is also configured to perform decompression of the variable length compressed data using the geometry shader unit.

    摘要: Multiprocessor graphics systems support distributed antialiasing. In one embodiment, two (or more) graphics processors each render a version of the same image, with a difference in the sampling location (or locations) used for each pixel. A display head combines corresponding pixels generated by different graphics processors to produce an antialiased image. This distributed antialiasing technique can be scaled to any number of graphics processors.

    摘要: Multichip graphics processing subsystems include at least three distinct graphics devices (e.g., expansion cards) coupled to a high-speed bus (e.g., a PCI Express bus) and operable in a distributed rendering mode. One of the graphics devices provides pixel data to a display device, and at least one of the other graphics devices transfers the pixel data it generates to another of the devices via the bus to be displayed. Where the high-speed bus provides data transfer lanes, allocation of lanes among the graphics devices can be optimized.

    摘要: Coherence of displayed images is provided for a graphics processing systems having multiple processors operating to render different portions of a current image in parallel. As each processor completes rendering of its portion of the current image, it generates a local ready event, then pauses its rendering operations. A synchronizing agent detects the local ready event and generates a global ready event after all of the graphics processors have generated local ready events. The global ready signal is transmitted to each graphics processor, which responds by resuming its rendering activity.
