Abstract: A computer system comprising a graphics processor, a frame buffer, a display device, a system agent operable to detect an absence of active software applications and system configurations capable of rendering a disruptive user experience during system suspend, and a memory for storing instructions, that when executed perform a method of entering a power conservation state. The method comprises detecting a system idle event, activating the frame buffer, and storing display information in the frame buffer from the graphics processor. The method further comprises initiating a power reduction state for the graphics processor, self-refreshing the display device during the power reduction state with the display information stored in the frame buffer, and initiating a system suspend comprising a power reduction state for the computer system provided the system agent detects the absence of disruptive software and system configurations.

Abstract: A solution is proposed for processing input in a lower power user interface of touch-sensitive display panels. According to an embodiment, a mobile computing device is placed in the low power mode. During this mode, the sensor controller produces a raw event/interrupts on a detected touch. Upon detecting a touch, the sensor controller also automatically increases the scan rate of the touch sensor, while the triggered event or interrupt proceeds to wake the system into a higher power state. Subsequent touch data received while the system is booting into the higher power state is buffered by the timing controller, or by a bridge chipset, while the processor(s) in the power up. When awake, the processor(s) collect the touch samples from the buffer, and processes the touch samples, generating updated displays where necessary.

Abstract: A solution is proposed to perform display updates in a lower power user interface. According to one embodiment, the display panel is placed in the lower possible refresh rate that can be supported. Rendered updates are presented to the displays at the fasted possible pixel rates the communication interface between the rendering component to the display panel can support, and a buffer on the receiving end of the display receives and stores updated frames as they are rendered and transmitted. Subsequent display updates (generated in response to subsequent sensor input, for example) may be created and transmitted as soon as the preceding display frames are buffered. In the meantime, as soon as the update frame is transmitted, the timing controller of the display panel is instructed to interrupt the current refresh period and to immediately rescan the frame.

Abstract: Various embodiments relating to reducing memory bandwidth consumed by a continuous scan display screen are provided. In one embodiment, scoring criteria are applied to a reference image of a first image format having a first bit depth to generate an image conversion score. The scoring criteria are based on a histogram of one or more characteristics of the reference image. If the image conversion score is greater than a threshold value, then the reference image is converted to a modified image of a second image format having a second bit depth less than the first bit depth, and the modified image is scanned onto the continuous scan display screen. If the image conversion score is less than the threshold value, then the reference image is scanned onto the continuous scan display screen.

Abstract: One embodiment of the present invention sets forth a method for accessing display configuration information in a multi-graphics-processing-unit (multi-GPU) system, which includes the steps of asserting a select signal to steer the display configuration information of a display device, which is coupled to a discrete GPU (dGPU), to a motherboard GPU (mGPU) in the multi-GPU system if dGPU is unavailable, and validating the display configuration information prior to availing the dGPU or the display device as an option to be selected.

Abstract: A method and apparatus for controlling sparse refresh of a self-refreshing display device coupled to a graphics controller are disclosed. The display device includes capabilities to drive the display based on video signals generated from a local frame buffer. The graphics controller may optimally be placed in one or more power-saving states when the display device is operating in a panel self-refresh mode. When exiting the power-saving state to update the image displayed by the display device, a fast-resume initialization routine may be run to reconfigure the GPU when operating in a sparse refresh mode, i.e., where the image being displayed on the display device is updated infrequently. In such cases, the graphics controller may be configured to receive instructions and data from a central processing unit via an alternative low-bandwidth communications path instead of the high-bandwidth communications path used in normal operation.

Abstract: In an apparatus according to one embodiment of the present disclosure, a communications link comprises a first device and a second device communicating with each other via the communications link at a plurality of different speeds. However, prior to communicating via the communications link for the first time at a second speed, the first device and second device complete a first training cycle at the second speed. Further, during this first training cycle for the second speed, the first training cycle for the second speed will pause before the first training cycle at the second speed completes, and the first device and second device communicate at a first speed for a period of time before returning to the paused first training cycle at the second speed. When the paused first training cycle for the second speed continues, the first training cycle for the second speed will continue where it had paused.

Abstract: Embodiments of the present disclosure provide techniques for identifying a display when a graphics processing unit (GPU) connected to the display via a display control bus is in a low power state. By providing a separate microcontroller with a parallel connection to the display control bus, the microcontroller may detect the presence of a display device even when the GPU is in the low power state. In response to detecting the display device, the microcontroller may notify a motherboard chipset (e.g., via an interrupt) prompting the motherboard chipset to initiate a sequence to bring the GPU out of the low power state.

Abstract: A system, method, and computer program product are provided for a dynamic display refresh. In use, a state of a display device is identified in which an entirety of an image frame is currently displayed by the display device. In response to the identification of the state, it is determined whether an entirety of a next image frame to be displayed has been rendered to memory. The next image frame is transmitted to the display device for display thereof, when it is determined that the entirety of the next image frame to be displayed has been rendered to the memory. Further, a refresh of the display device is delayed, when it is determined that the entirety of the next image frame to be displayed has not been rendered to the memory.

Abstract: A secure virtual machine system, method, and computer program product implemented on a processor are provided for processing a third party's content for output. At least one processor is provided. Additionally, at least one secure virtual machine implemented on the processor is provided for interpreting a second party's program that processes and outputs a third party's content. The virtual machine system abstracts the underlying processor hardware allowing implementation variations across products to execute the same program identically. Furthermore, the scope of the programmable operations, the types of input & output variables, and execution of programs within the processor, is deliberately constrained within the virtual machine environment, in order to mitigate potential security leaks by programs, and to ensure confidentiality of second party's secrets, and third party's content as managed by the second party's program.

Abstract: An aspect of the present invention proposes a solution to allow low-cost flat panel displays without light guides to maintain a high quality image display via enhancement of pixel data to account for non uniform brightness. According to one embodiment, each pixel of a display is mapped to the brightness (intensity) of illumination that reaches the pixel. Regional pixel gains are calculated and applied on a per pixel basis to compensate for the non-uniform brightness across the screen. According to such an embodiment, even low cost flat panel displays experiencing non-uniform brightness can be used to render high quality images.

Abstract: A solution is proposed that allows power savings via enhancement of pixel data to compensate for reducing backlight intensity levels. According to one embodiment, each pixel of a display is sorted according to the brightness (intensity) of the pixel. Regional pixel gains are calculated and applied on a per pixel basis so as not to exceed a quality threshold. The intensity of the backlight corresponding to each region may be decreased by an equivalent amount, thereby reducing (potentially significantly) the power consumed to operate the backlight while maintaining the color intensity in the image due to the applied pixel gains.

Abstract: A solution is proposed that performs global histogramming of pre-regionally-enhanced pixel values accounting for inter-regional illumination contributions to verify that over-saturation of an image is prevented. According to an embodiment, pixel values that have been regionally enhanced—that is, with applied gains calculated for the respective regions—are further added to illumination values corresponding to the pixel values, with the resultant summed pixel values being histogrammed again to determine the amount of over-saturated pixels. An over-abundance of over-saturated pixels results in a calculation of a global modifier applied to each pixel to reduce the number of over-saturated pixels below an acceptable threshold.
