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 device may include a display and image processing circuitry. The image processing circuitry may receive a frame of image data for display by the display and at least one external display coupled to the electronic device, where the frame of image data comprises an active portion and an idle portion, wherein the active portion comprises data for presenting one or more images via the display and the at least one external display, receive a signal from a controller during the idle portion of the frame of image data, and initiate processing of a first line of active portion in response to receiving the signal. In this way, the frame of image data being displayed by the display and the at least one external display may be in sync.
