Abstract: A display may store extended display identification data for communicating the capabilities of the display to a source device such as a graphics processing unit. The extended display identification data may include a red primary color value, a green primary color value, and a blue primary color value. The primary color values in the extended display identification data may be determined during manufacturing. For example, a light sensor may measure the native primary colors of the display, and calibration computing equipment may determine if the native primary colors of the display are within a target color gamut. If the native primary colors of the display are outside of the target color gamut by an amount larger than a threshold, the primary color values in the extended display identification data may be adjusted to account for the color variation.

Abstract: Methods and apparatus for switching between different video processing modes in an apparatus. In a first mode, minimal processing of the video frames may be performed by the apparatus prior to feeding the frames to a display controller. In a second mode, the apparatus may perform additional rendering of the video frames including compositing of other graphical input with the rendered video frames to generate display frames that may be fed to the display controller. To conserve power, the apparatus may operate in or switch to the first mode when the additional rendering and compositing is not required or when the device is in a low power mode, and operate in or switch to the second mode when the additional rendering and compositing is required to render desired graphical effects.

Abstract: Systems, methods, and computer readable media to improve the operation of a display system are disclosed. Techniques disclosed herein selectively darken a region of an image so that when text or other information is rendered into that region, the contrast between the text or other information and the underlying image in that area is sufficient to ensure the text or other information is visible and readable. In one embodiment, a region into which information is to be rendered may be combined or blended with tone mapped values of those same pixels in accordance with a given function, where the function gives more weight to the tone mapped pixel values the closer those pixels are to the midline of the region and more weight to untone-mapped image pixel values the further those pixels are from the midline of the region.

Abstract: Lossless image compression using differential transfers may involve an image compression unit receiving image data for an image in a sequence of images and transmitting the image data such that image data for at least some image tiles is transmitted using lossy compression due to resource limitations. The image compression unit may then receive image data for a subsequent image in the sequence and determine that the image data for at least some tiles does not change relative to the image data for corresponding tiles of the previous image. The image compression unit may then transmit image data in a manner sufficient to create lossless versions of tiles for which lossily compressed image data was sent previously.

Abstract: The disclosed embodiments provide a system that configures a graphics-processing unit (GPU) in a computer system. During operation, the system predicts an incoming workload to the GPU. Next, the system identifies an operational floor for the GPU based on the incoming workload. Finally, the system uses the operational floor to configure the subsequent execution of the GPU, wherein the operational floor facilitates processing of the incoming workload by the GPU.

Abstract: The disclosed embodiments provide a system that drives a display from a computer system. During operation, the system detects an idle state in a first graphics-processing unit (GPU) used to drive the display. During the idle state, the system switches from using the first GPU to using a second GPU to drive the display and places the first GPU into a low-power state, wherein the low-power state reduces a power consumption of the computer system.

Abstract: Systems, methods, and devices for dynamically mapping and remapping memory when a portion of memory is activated or deactivated are provided. In accordance with an embodiment, an electronic device may include several memory banks, one or more processors, and a memory controller. The memory banks may store data in hardware memory locations and may be independently deactivated. The processors may request the data using physical memory addresses, and the memory controller may translate the physical addresses to hardware memory locations. The memory controller may use a first memory mapping function when a first number of memory banks is active and a second memory mapping function when a second number is active. When one of the memory banks is to be deactivated, the memory controller may copy data from only the memory bank that is to be deactivated to the active remainder of memory banks.

Abstract: In some implementations, a computing device can perform multi-display alignment through observed user interactions. The computing device can receive user input aligning a first alignment object on a first display device with a second alignment object on a second display device. The computing device can align the display buffers for each display device based on the positions of the alignment objects in each display buffer corresponding to each display device. The computing device can align display buffers based on observed movements of graphical objects between multiple display devices. When display buffers corresponding to the display devices are misaligned, the user may correct the path of a graphical object when moving the graphical object between display devices. The computing device can detect the correction and align the display buffers of the display devices so that graphical objects are presented at the appropriate locations when moved between the display devices.
