摘要： One embodiment of the present invention sets forth a technique for displaying high-resolution images using multiple graphics processing units (GPUs). The graphics driver is configured to present one virtual display device, simulating a high-resolution mosaic display surface, to the operating system and the application programs. The graphics driver is also configured to partition the display surface amongst the GPUs and transmit commands and data to the local memory associated with the first GPU. A video bridge automatically broadcasts this information to the local memories associated with the remaining GPUs. Each GPU renders and displays only the partition of the display surface assigned to that particular GPU, and the GPUs are synchronized to ensure the continuity of the displayed images. This technique allows the system to display higher resolution images than the system hardware would otherwise support, transparently to the operating system and the application programs.

摘要： In a computer system having a CPU and a graphics subsystem, a device for dynamic graphics subsystem clock adjustment. A clock pulse generator is used for generating a clock frequency. The clock frequency is coupled to the graphics subsystem and is used by the graphics subsystem to synchronize and pace its internal operations. The clock frequency generated by the generator is variable over a range. A controller is coupled to the clock pulse generator, for adjusting the clock frequency from the clock pulse generator over the range. The controller interfaces with the computer system through an interface coupled to the controller. Through the interface, the controller communicates with the computer system or graphics subsystem and determines a load placed on the graphics subsystem. The controller adjusts the clock frequency generated by the clock pulse generator such that the clock frequency increases when the load on the graphics subsystem increases and the clock frequency decreases when the load on the graphics subsystem decreases, dynamically adjusting the clock frequency in response to the load on the graphics subsystem.

摘要： Disclosed are an apparatus, a computer device, a system, computer readable media and a method for using graphics processing unit (“GPU”)-generated data to characterize, in-situ, the ability of a cable to reliably carry digitized video, among other things. In one embodiment, a computing device includes a processor coupled via a system bus to a graphics engine and a video cable-testing apparatus. This apparatus has an input port configured to couple to the digitized video cable to receive pixel data generated by the graphics engine. It also has a signal integrity evaluator (“SIE”) configured to identify the digitized video cable as the source an amount of data corruption, the amount of data corruption being a function of the pixel data. The signal integrity evaluator includes a classifier to classify the amount of data corruption into classes that each represents various degrees of degradation of the computer-generated video images.

摘要： An apparatus and method is provided that increases the throughput of graphics commands transferred between a system bridge and a graphics subsystem. In one embodiment, the apparatus tags each of the multiple graphics commands to indicate a specific order of the multiple graphics commands. Each of the tagged multiple graphics commands are then assigned to one of a plurality of busses. The plurality of busses transfer each of the multiple graphics commands across its assigned one the plurality of busses. After being transferred across the plurality of busses, the multiple graphics commands are put back in their original specific order through the use of the tags. The reordered (also referred to as regrouped) multiple graphics commands are then transferred to the graphics subsystem. In another embodiment, multiple graphics commands are transferred over a plurality of busses to functional components of the graphics subsystem.
