| 20100007673 | Double-Buffering Of Video Data - Data is written to one of two frame buffers in write access cycles having write and non-write sub-periods. Data is read out to a display device from the other of the two frame buffers in read access cycles having read and non-read sub-periods. The writing of data and the reading of data are switched to a respective opposite frame buffer during a switching opportunity, a switching opportunity occurring when a read access cycle is in a non-read sub-period and a write access cycle is in a non-write sub-period. A count of the number of times a switching opportunity is not executed because a read access cycle is in a non-read sub-period while a write access cycle is in a write sub-period is incremented. If the count exceeds a particular threshold, a write access cycle subsequent to the count exceeding the threshold is masked. When a write access cycle is a masked data is not written into a buffer. | 01-14-2010 |

The write-switch point determiner determines a safe write-switch point in the first one of the two frame buffers. The safe write-switch point is determined, at least in part, by an average rate at which data is written to the frame buffers and an average rate at which data is read from the frame buffers. The write-buffer selector determines if the reading of the first frame has progressed beyond the safe write-switch point, and selects one of the two frame buffers to write a second frame of pixel data based on the determination. | 10-21-2010 |
| 20140247270 | Switching Video Streams for a Display Without a Visible Interruption - The disclosed embodiments provide a system that facilitates driving a display in a computer system. During operation, the system receives an input video stream from a graphics source, wherein the input video stream comprises a sequence of video frames. Next, the system directs the input video stream through a set of two or more memory buffers including a front buffer and a back buffer to produce an output video stream, which is used to drive the display. While directing the input video stream through the set of memory buffers, the system writes a video frame from the input video stream into the back buffer, and concurrently drives the output video stream from a preceding video frame in the front buffer. When the writing of the video frame completes, the system switches buffers so that the back buffer becomes the front buffer, which drives the output video stream, and the front buffer becomes either a spare buffer or the back buffer, which receives a subsequent frame from the input video stream. | 09-04-2014 |
