Abstract: Systems, apparatuses, and methods for time shifting tasks in a computing system. A system may include a display control unit configured to process pixels for display. The display control unit may include at least one or more pixel processing pipelines, a control unit, and a pixel buffer. The control unit may be configured to monitor the amount of data in the pixel buffer and set the priority of pixel fetch requests according to the amount of data in the pixel buffer. If the control unit determines that an inter frame period will occur within a given period of time, the control unit may prevent the priority of pixel fetch requests from being escalated if the amount of data in the pixel buffer falls below a threshold. The control unit may also be configured to fill the buffers of the display control unit with as much data as possible during the inter frame period.

Abstract: Systems, apparatuses, and methods for improved power management techniques. An apparatus may include a display control unit, a communication fabric, a memory controller, a memory cache, and a memory. When the memory is power-gated, and the display control unit needs to fetch pixel data, the display control unit may send a wake-up signal to the memory before sending a wake-up signal to the communication fabric. The display control unit may then issue the pixel fetch request later. Additionally, if the display control unit determines that the pixel data has a high probability of being cached, then the display control unit may not send a wake-up signal to the memory, and the display control unit may issue the request earlier. More generally, the display control unit may send wake-up signals to multiple components in a manner which accounts for the wake-up latency of each component.

Abstract: A method and device for data compression are presented, in which a data processor may receive a packet of image data which includes four groups of N bits, where N is an integer greater than 2. The data processor may compress the received packet of data, such that a total number of bits for the converted packet is less than four times N. The data processor may compress the received packet of image data by reducing the resolution of three of the values while maintaining the resolution of the fourth value. To reduce the resolution of the three values, the data processor may apply a dithering formula to the values. The data processor may then send the converted packet via an interface.

Abstract: In an embodiment, a system includes a display processing unit configured to process a video sequence for a target display. In some embodiments, the display processing unit is configured to composite the frames from frames of the video sequence and one or more other image sources. The display processing unit may be configured to write the processed/composited frames to memory, and may also be configured to generate statistics over the frame data, where the generated statistics are usable to encode the frame in a video encoder. The display processing unit may be configured to write the generated statistics to memory, and the video encoder may be configured to read the statistics and the frames. The video encoder may be configured to encode the frame responsive to the statistics.

Abstract: A display pipe is configured to generate output frames for display. Additionally, the display pipe may be configured to compress an output frame and write the compressed frame back to memory responsive to detecting static content in successive output frames. The display pipe may also be configured to determine to selectively allow write-back logic to operate when doing so will not cause a pixel underrun to the display. If an underrun might occur, write-back logic is temporarily disabled. If write-back is successful, the display pipe may read the compressed frame from memory for display instead of reading the source frames for compositing and display.

Abstract: Systems, apparatuses, and methods for synchronizing backlight adjustments to frame updates in a display pipeline. A change in the ambient light is detected and as a result, backlight settings are adjusted. To offset a reduction in the backlight, the color intensity in the frames is increased. While the change in ambient light is detected asynchronously, the adjustment to the backlight settings and color intensity is synchronized to a frame update via a virtual channel for the auxiliary channel of the display interface.

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 with pixels that present an image based on image data and an application processor that generates the image data. The electronic device may include a display pipeline coupled to the electronic display and the application processor. The display pipeline may receive first image data from the application processor corresponding to a first color space used by the application processor. The display pipeline may apply a color mapping relationship to the first image data to generate second image data. The color mapping relationship may define a transform to apply to the first image data to generate the second image data corresponding to a second color space used by the electronic display. The display pipeline may transmit the second image data to a display driver that operates the electronic display to emit light according to the second image data.
