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.

摘要： Systems and methods for providing on-demand memory management. In response to a mapping request from a device driver or other program, a first portion of the memory is mapped to one or more virtual addresses in a first region of a virtual memory space so that it can be directly accessed by the CPU. In response to an unmapping request the first portion of the memory is unmapped. Mapping and unmapping requests may be made at any time.

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： 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.
