| 20090079747 | Distributed Antialiasing In A Multiprocessor Graphics System - 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. | 03-26-2009 |
| 20090189908 | Display Balance / Metering - Method, apparatuses, and systems are presented for processing a sequence of images for display using a display device involving operating a plurality of graphics devices, including at least one first graphics device that processes certain ones of the sequence of images, including a first image, and at least one second graphics device that processes certain other ones of the sequence of images, including a second image, delaying processing of the second image by the at least one second graphics device, by a specified duration, relative to processing of the first image by the at least one first graphics device, to stagger pixel data output for the first image and pixel data output for the second image, and selectively providing output from the at least one first graphics device and the at least one second graphics device to the display device. | 07-30-2009 |
| 20090207178 | Video Processing with Multiple Graphical Processing Units - One embodiment of a video processor includes a first media processing device 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 data processed by the second media processing device to the first media processing 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 enabling the video processor to process video data more quickly than a single-GPU video processor. | 08-20-2009 |
| 20100026689 | VIDEO PROCESSING SYSTEM, METHOD, AND COMPUTER PROGRAM PRODUCT FOR ENCRYPTING COMMUNICATIONS BETWEEN A PLURALITY OF GRAPHICS PROCESSORS - A video processing system, method, and computer program product are provided for encrypting communications between a plurality of graphics processors. A first graphics processor is provided. Additionally, a second graphics processor in communication with the first graphics processor is provided for collaboratively processing video data. Furthermore, such communication is encrypted. | 02-04-2010 |
| 20100026690 | SYSTEM, METHOD, AND COMPUTER PROGRAM PRODUCT FOR SYNCHRONIZING OPERATION OF A FIRST GRAPHICS PROCESSOR AND A SECOND GRAPHICS PROCESSOR IN ORDER TO SECURE COMMUNICATION THEREBETWEEN - A system, method, and computer program product are provided for synchronizing operation of a first graphics processor and a second graphics processor in order to secure communication therebetween. A first graphics processor is provided for processing video data. In addition, a second graphics processor is provided for processing the video data. Furthermore, a data structure is provided for use in synchronizing operation of the first graphics processor and the second graphics processor in order to secure communication therebetween. | 02-04-2010 |
| 20100026692 | HYBRID GRAPHIC DISPLAY - A method of displaying graphics data is described. The method involves accessing the graphics data in a memory subsystem associated with one graphics subsystem. The graphics data is transmitted to a second graphics subsystem, where it is displayed on a monitor coupled to the second graphics subsystem. | 02-04-2010 |
| 20100053177 | GRAPHICS PROCESSING SYSTEM INCLUDING AT LEAST THREE BUS DEVICES - 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. | 03-04-2010 |
| 20100066747 | MULTI-CHIP RENDERING WITH STATE CONTROL - Circuits, methods, and apparatus that provide multiple graphics processor systems where specific graphics processors can be instructed to not perform certain rendering operations while continuing to receive state updates, where the state updates are included in the rendering commands for these rendering operations. One embodiment provides commands instructing a graphics processor to start or stop rendering geometries. These commands can be directed to one or more specific processors by use of a set-subsystem device mask. | 03-18-2010 |
| 20100123725 | Picture Processing Using A Hybrid System Configuration - A system and method for adjusting pictures minimizes the impact on graphics processing performance of a discrete processor. A hybrid system configuration includes the discrete processor and an integrated processor, where the discrete processor typically consumes more power and provides greater processing performance compared with the integrated processor. A picture is produced by a video or graphics engine of a discrete processor within a hybrid system. Each picture is then transferred to a back buffer in the host processing memory. The picture is analyzed to produce picture analysis results that are used to generate adjustment settings. The back buffer is swapped to become the front buffer and the adjustment settings are applied to the picture by an integrated processor to display an adjusted picture. The adjustment may be used in conjunction with power saving techniques to maintain the image quality when display backlighting is reduced. | 05-20-2010 |
| 20100271375 | ADAPTIVE LOAD BALANCING IN A MULTI PROCESSOR GRAPHICS PROCESSING SYSTEM - Systems and methods for balancing a load among multiple graphics processors that perform different portions of a rendering task. A rendering task is partitioned into portions for each of two (or more) graphics processors. The graphics processors perform their respective portions of the rendering task and return feedback data indicating completion of the assigned portion. Based on the feedback data, an imbalance can be detected between respective loads of two of the graphics processors. In the event that an imbalance exists, the rendering task is re-partitioned to increase the portion assigned to the less heavily loaded processor and to decrease the portion assigned to the more heavily loaded processor. | 10-28-2010 |
