  • Patent number: 8629877
    Abstract: A method of dynamic load-balancing in a PC-based computing system employing a multiple GPU-based graphics pipeline architecture supporting multiple modes of GPU parallelization. During the execution of the graphics application, the stream of geometrical data and said graphics commands is analyzed, and the mode of parallelization of the GPUs during each frame, is determined using results of the analysis of the stream of geometrical data and graphics commands, and one or more policies for determining the mode of parallelization. The stream of geometrical data and graphic commands is distributed to the GPUs according to the determined mode of parallelization. During the generation of each frame, one or more of GPUs are used to process the stream of geometrical data and graphic commands, or a portion thereof, while operating in the parallelization mode, so as to generate pixel data corresponding to at least a portion of an image of 3D object.

  • Patent number: 8624907
    Abstract: Embodiments provide techniques for the analysis of graphics applications. For instance, an apparatus may include a graphics application program interface (API), a graphics engine, and a graphics analysis tool. The graphics analysis tool may receive multiple draw calls issued to the graphics API, and arrange the draw calls into multiple sequences, each sequence corresponding to a particular render target. From this information various analysis tasks may be performed. For instance, overdraw images may be generated. Such overdraw images may be enhanced to improve their dynamic range. Also, pixel histories may be generated based on corresponding pixel selections. The effect of draw calls on selected pixels may also be determined. Further, such tasks may be performed on a per render target basis.

    Abstract: A virtual display system, compatible with Windows Display Driver Model (WDDM), facilitates extending a display virtually, to any display target, such as a window on the primary display, a tablet, or another personal computer altogether. The virtual WDDM display system device has a PCI filter driver, a virtual device user mode driver and a virtual device kernel mode driver. The virtual WDDM display system interacts with a physical WDDM display device, which it uses as a surrogate renderer. The PCI filter driver is used to force enumeration of a virtual display device. The virtual device kernel mode driver uses chained callbacks at increasing IRQ levels for simulating an interrupt from a real hardware device. Continuous segments in memory are used to simulate video memory on a physical display device. DirectX extensions are used to facilitate expectations at the hardware level.

  • Patent number: 8520014
    Abstract: An information handling system includes a host processing system and a remote processing system. The host processing system includes a display, a host processor, and a video multiplexer that receives a video signal from the host processor and outputs the video signal to the display. The remote processing module is coupled to the host processing system and includes a remote processor configured to output a second video signal, and an interface between the host processing system and the remote processing system. The interface includes a video output channel configured to provide the second video signal to the video multiplexer. The video multiplexer is further configured to receive the second video signal and to output the second video signal to the display during a reduced operating state of the host processing system.

  • Patent number: 8508493
    Abstract: Disclosed herein are various embodiments of circuits and methods for reducing electromagnetic interference in mutual capacitance measurement or sensing systems, devices, components and methods such as capacitive touchscreens. Charge integrator circuits and switched capacitance filtering circuits are disclosed that improve the signal-to-noise ratio (or the ratio of a desired sensed mutual capacitance signal to an undesired EMI signal) in a capacitive sensor readout circuit without the need to increase the amplitude of the drive signal. The various embodiments of the charge integrator and switched capacitance filtering circuits described herein permit an improvement in noise immunity without requiring the excessive power levels typically associated with high amplitude drive circuitry, and moreover result in boosting signal-to-noise ratios during early stages of signal processing.

  • Patent number: 8508540
    Abstract: A method, system and an apparatus of resonant induction to power a graphics processing unit (GPU) are disclosed. In one embodiment, a resonant induction system is described. The resonant induction system includes a transmitter circuit tuned to a resonant frequency. The transmitter circuit generates a non-radiative magnetic field when a control current is passed through the transmitter circuit. The resonant induction system also includes a receiver circuit, resonantly coupled to the non-radiative magnetic field generated by the transmitter circuit, and tuned to the resonant frequency of the transmitter circuit. The receiver circuit is located in a GPU. The transmitter circuit and the receiver circuit are resonantly coupled to each other at the resonant frequency. A control current source supplies the control current to the transmitter circuit. A feedback module may be communicatively coupled to the GPU to determine a power requirement of a particular computer graphics application.

  • Publication number: 20130194283
    Abstract: The display apparatus includes: an image processor which processes an image signal; a display which displays an image based on the processed image signal; an interface to which an upgrading apparatus for processing the image signal is connected; and a controller which controls the interface to cut off power supplied to the upgrading apparatus upon receiving a user's selection to change the upgrading apparatus mode from an active mode to a passive mode. Thus, the active and passive modes of the upgrading apparatus are changed without removing the upgrading apparatus and without rebooting the display apparatus, thereby improving user's convenience.

  • Patent number: 8493395
    Abstract: A method and system for overriding state information programmed into a processor using an application programming interface (API) avoids introducing error conditions in the processor. An override monitor unit within the processor stores the programmed state for any setting that is overridden so that the programmed state can be restored when the error condition no longer exists. The override monitor unit overrides the programmed state by forcing the setting to a legal value that does not cause an error condition. The processor is able to continue operating without notifying a device driver that an error condition has occurred since the error condition is avoided.

  • Patent number: 8487943
    Abstract: Many computing device may now include two or more graphics subsystems. The multiple graphics subsystems may have different abilities, and may, for example, consume differing amount of electrical power, with one subsystem consuming more average power than the others. The higher power consuming graphics subsystem may be coupled to the device and used instead of, or in addition to, the lower power consuming graphics subsystem, resulting in higher performance or additional capabilities, but increased overall power consumption. By transitioning from the use of the higher power consuming graphics subsystem to the lower power consuming graphics subsystem, while placing the higher power consuming graphics subsystem in a lower power consumption mode, overall power consumption is reduced. A processor executes application software and driver software. The driver software includes first and second driver components for respectively controlling operation of the first and second graphics subsystems.
