VIDEO PROCESSING WITH MULTIPLE GRAPHICS PROCESSING UNITS

摘要

One embodiment of a video processor includes a first media processing devic e coupled to a first memory and a second media processing device coupled to a second memory. The second media processing device is coupled to the first media processing device via a scalable bus. A software driver configures the media processing devices to provide video processing functionality. The scalable bus carries video da ta processed by the second media processing device to the first media processin g device where the data is combined with video data processed by the first media processing device to produce a processed video frame. The first media processing device transmits the combined video data to a display device. Each media processing device is configured to process separate portions of the video data, thereby enabli ng the video processor to process video data more quickly than a single-GPU video processor.
