Abstract: Systems, apparatuses, and methods for performing mid-frame blanking. A first portion of a frame is driven to a display and then a first mid-frame blanking interval is generated. Following this first mid-frame blanking interval, a second portion of the frame is driven to the display, followed by a second mid-frame blanking interval, followed by a third portion of the frame, and so on. Any number of mid-frame blanking intervals may be introduced in a given frame. During each mid-frame blanking interval, touch sensing is performed to detect touch events on the screen for in-cell touch type displays. For displays with touch sensors electrically separated from the display common voltage layer, special sense scan steps are performed during mid-frame blanking intervals. By performing touch sensing or special sense scan steps during a frame rather than only at the end of a frame, the performance of touch sensing is improved.

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: A system and method for efficiently processing access requests for a shared resource. A computing system includes a shared memory accessed by multiple requestors. Control logic determines two requestors seek to access a same data block within the shared memory. In response to the determination, a first requestor of the two requestors sends a read request to the shared memory on behalf of the two requestors. The second requestor of the two requestors is prevented from sending a read request. In response to detecting data is returned as a response to the read request generated by the first requestor, both the first requestor and the second requestor retrieve the data. In response to detecting a given requestor of the two requestors generates an indication that it is unable to continue retrieving the same response data, the two requestors return to generating separate, respective read requests.

Abstract: Systems, apparatuses, and methods for driving a split display with multiple display pipelines. Frames for driving a display are logically divided into portions, a first display pipeline drives a first portion of the display, and a second display pipeline drives a second portion of the display. To ensure synchronization between the two display pipelines, a repeat vertical blanking interval (VBI) signal is generated if either of the display pipelines has not already received the frame packet with configuration data for the next frame. When the repeat VBI signal is generated, both display pipelines will repeat processing of the current frame.

Abstract: A video display pipe used for processing pixels of video and/or image frames may include edge Alpha registers for storing edge Alpha values corresponding to the edges of an image to be translated across a display screen. The edge Alpha values may be specified based on the fractional pixel value by which the image is to be moved in the current frame. The video pipe may copy the column and row of pixels that are in the direction of travel, and may apply the edge Alpha values to the copied column and row. The edge Alpha values may control blending of the additional column and row of the translated image with the adjacent pixels in the original frame, providing the effect of the partial pixel movement, simulating a sub pixel rate of movement.

Abstract: An electronic device (10) may include a display (12) panel and an image data source (38) designed to determine a differing region (84) in an image frame by comparing source image data (78) and image data corresponding with a previous image frame (72). The electronic device (10) may also include a display pipeline (36) between the image data source (38) and the display (12) panel. The display pipeline (36) may include image processing circuitry (27) 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 (36) may determine a crop region (116) by converting the differing region (84) to the display space and determine a partial frame region (120), based on the image data to be spatially processed, by the image processing circuitry (27). The display pipeline (36) may also determine and retrieve a fetch region (86) smaller than the image frame by converting the partial frame region to the source space.

Abstract: In some embodiments, a system includes a memory system, a real-time computing device, and a controller. The real-time computing device stores data within a local buffer having a corresponding storage threshold, where the data satisfies the storage threshold, and where the storage threshold is based on a latency of the memory system and an expected rate of utilization of the data of the local buffer. The controller detects that the memory system should perform an operation, where the memory system is unavailable to the real-time computing device during the operation. In response to detecting that an amount of time for the operation exceeds an amount of time corresponding to the storage threshold, the controller overrides the storage threshold. The controller may override the storage threshold by modifying the storage threshold and by overriding a default priority for access requests of the real-time computing device to the memory system.

Abstract: In an embodiment, a display pipe includes one or more translation units corresponding to images that the display pipe is reading for display. Each translation unit may be configured to prefetch translations ahead of the image data fetches, which may prevent translation misses in the display pipe (at least in most cases). The translation units may maintain translations in first-in, first-out (FIFO) fashion, and the display pipe fetch hardware may inform the translation unit when a given translation or translation is no longer needed. The translation unit may invalidate the identified translations and prefetch additional translation for virtual pages that are contiguous with the most recently prefetched virtual page.
