摘要： A bridge associated with a broadcast aperture facilitates the transfer of rendering commands and data between a processor and multiple graphics devices. The bridge receives data written by the processor to the broadcast aperture and forwards it to multiple graphics devices, eliminating the need for the processor to perform duplicative(?) write operations. During system initialization, a broadcast aperture is allocated to the bridge in address space based on an aperture size value set using a system configuration utility and stored in system configuration memory. A graphics driver activates the broadcast aperture by sending unicast aperture parameters associated with the multiple graphics devices to the bridge via a bridge driver. Upon activating the broadcast aperture, multiple graphics devices can be operated in parallel to improve rendering performance. Parallel rendering techniques include split-frame, alternate frame, and combined split- and alternate frame rendering.

摘要： Embodiments of the invention accelerate at least one special purpose processor, such as a GPU, or a driver managing a special purpose processor, by using at least one co-processor. Advantageously, embodiments of the invention are fault-tolerant in that the at least one GPU or other special purpose processor is able to execute all computations, although perhaps at a lower level of performance, if the at least one co-processor is rendered inoperable. The co-processor may also be used selectively, based on performance considerations.

摘要： Systems and methods for using a graphics processor to perform RAID parity functions may improve disk access performance. A method is provided for configuring a graphics processor to perform XOR parity computations when data is written to the RAID array. Another method is provided for configuring the graphics processor to perform the XOR parity computations to restore data when a disk is damaged. Using the graphics processor as a coprocessor to offload parity computations from a central processing unit may improve disk access performance and overall system performance.

摘要： Techniques are disclosed for peer-to-peer data transfers where a source device receives a request to read data words from a target device. The source device creates a first and second read command for reading a first portion and a second portion of a plurality of data words from the target device, respectively. The source device transmits the first read command to the target device, and, before a first read operation associated with the first read command is complete, transmits the second read command to the target device. The first and second portions of the plurality of data words are stored in a first and second portion a buffer memory, respectively. Advantageously, an arbitrary number of multiple read operations may be in progress at a given time without using multiple peer-to-peer memory buffers. Performance for large data block transfers is improved without consuming peer-to-peer memory buffers needed by other peer GPUs.

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.
摘要翻译：本发明的一个实施例提出了使用IGPU和DGPU执行细粒度渲染预测的技术。图形驱动程序将3D对象分成三个三角形。 IGPU通过修改的渲染管线处理每批三角形，以确定批次是否被剔除。 IGPU将比特写入与批次的可见性相对应的比特流中。 DGPU从比特流中读取比特流，并执行完整的渲染，包括着色，但仅在批次可以看到的批次的三角形中。有利地，这种渲染预测的方法提供了细粒度的淘汰，而不会增加不必要的开销，从而优化硬件资源和性能。
