摘要： In an embodiment, a display pipe is configured to composite one or more frames of images and/or video sequences to generate output frames for display. Additionally, the display pipe may be configured to compress an output frame and write the compressed frame to memory responsive to detecting static content in the output frames is detected. The display pipe may also be configured to read the compressed frame from memory for display instead of reading the frames for compositing and display. In some embodiments, the display pipe may include an idle screen detect circuit configured to monitor the operation of the display pipe and/or the output frames to detect the static content.

摘要： 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.

摘要： A graphics system may include one or more processing units for processing a current display frame, each processing unit including a plurality of parameter registers for storing parameter settings used in processing the current display frame. A parameter buffer in the graphics system may store frame packets, with each frame packet containing information corresponding to parameter settings to be used for at least one display frame. A control circuit coupled to the buffer and to the one or more processing units may retrieve and process a top frame packet from the parameter buffer to update one or more of the parameter registers according to the contents of the top frame packet. The control circuit may issue DMA requests to fill the parameter buffer with frame packets transferred from system memory, where the frame packets may be written by an application (or software) executing on a central processing unit.

摘要： A system and method for efficiently allocating data in a memory hierarchy. A system includes a memory controller for controlling accesses to a memory and a display controller for processing video frame data. The memory controller includes a cache capable of storing data read from the memory. A given video frame may be processed by the display controller and presented on a respective display screen. During processing, control logic within the display controller sends multiple memory access requests to the memory controller with cache hint information. For the frame data, the cache hint information may alternate between (i) indicating to store frame data read in response to respective requests in the memory cache and (ii) indicating to not store the frame data read in response to respective requests in the memory cache.

摘要： Systems, methods, and non-transitory media are presented that provide for improving color accuracy. An electronic display (12) includes a display region having multiple pixels each having multiple subpixels. The electronic device (10) also includes a display pipeline (36) coupled to the electronic display (12). The display pipeline (36) is configured to receive image data and perform white point compensation on the image data to compensate for a current drop in the display (12) to cause the display (12) to display a target white point when displaying white. The display pipeline (36) also is configured to correct white point overcompensation on the image data to reduce possible oversaturation of non-white pixels using the white point compensation. Finally, the display pipeline (36) is configured to output the compensated and corrected image data to the electronic display (12) to facilitate displaying the compensated and corrected image data on the display region.

摘要： 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.

摘要： 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.
