Abstract: Throttling circuitry may throttle the backlight reconstruction via backlight reconstruction and compensation circuitry in a display pipeline when power may be limited. This throttling of the display pipeline may limit a number of cycles that may be used for performing backlight reconstruction and compensation.

Abstract: A method may include receiving, via a processor, a frame of image data, such that the frame of image data may include an active portion and an idle portion. The active portion may include data for presenting one or more images via a first display of a first electronic device. The method may also include receiving a signal from a second electronic device during the idle portion of the frame of image data, such that the second electronic device is separate from the first display. The method may then involve initiating processing of the frame of image data in response to the signal being received from the second electronic device.

Abstract: An electronic device may include a display panel and an image data source designed to determine a differing region in the image frame by comparing source image data and image data corresponding with a previous image frame. The electronic device may also include a display pipeline between the image data source and the display panel. The display pipeline may include image processing circuitry to convert image data from a source space to a display space and image processing circuitry to spatially process the image data. The display pipeline may determine a crop region by converting the differing region to the display space and determine a partial frame region, based on the image data to be spatially processed, by the image processing circuitry. The display pipeline may also determine and retrieve a fetch region smaller than the image frame by converting the partial frame region to the source space.

Abstract: A device may include a display for displaying an image frame based on warped image data and image processing circuitry to generate the warped image data by warping input image data to account for one or more distortions associated with displaying the image. The image processing circuitry may include a two-stage cache architecture having an first cache and an second cache and warp the input image data by generating mapping data indicative of a warp between the input image space and the output image space and fetching the input image data to populate the first cache. Warping may also include populating the second cache with a grouping of pixel values from the first cache that are selected according to a sliding window that traverses the first cache based on the mapping data and interpolating between pixel values of the grouping to generate pixel values of the warped image data.

Abstract: An electronic display device has a panel that operates in conjunction with a light-emitting diode (LED) backlight. The device “slopes” or gradually ramps a change in brightness of an LED based on a target brightness value of the LED, a current brightness value of the LED, and temperature at the LED. The device also may limit power to the backlight based on an estimated power consumption of a current row of LEDs of the backlight and power consumption of the other rows of LEDs. The device also may determine a reduced voltage to supply to an LED based on a current to supply to the LED to cause the LED to operate. The device also may send an interrupt to the backlight to block updates to the backlight while image content is written to pixels of the panel. The device further compensates for aging of and temperature at an LED.

Abstract: Techniques are disclosed relating to securing hardware accelerators used by a computing device. In some embodiments, a computing device includes one or more processors configured to co-execute trusted processes and untrusted processes in an isolated manner that includes implementing a secure environment in which a set of security criteria is enforced for data of the trusted processes. The computing device further includes multiple heterogenous hardware accelerators configured to implement exclaves of the secure environment that extend enforcement of one or more of the set of security criteria within the hardware accelerators for data distributed to the hardware accelerators for performance of tasks associated with the trusted processes.
