Abstract: A processing system reduces latency and improves predictability of a scan out position to support graphics processing unit (GPU) front buffer rendering with a variable refresh rate (VRR) display. The GPU detects whether front buffer rendering such as inking is occurring on a frame-by-frame basis. In order to maintain a safe distance from the current scan out position and achieve low latency to improve the user experience, the GPU increases the refresh rate of the VRR display to a low-latency (high-frequency) fixed refresh rate in response to detecting front buffer rendering. In some embodiments, the GPU decreases the refresh rate in response to detecting a static screen to save power.

Abstract: A graphics processing unit (GPU) instructs a display control module to capture content and display captured content in response to the refresh rate of a display exceeding a frame generation rate of the GPU. Rather than re-transmit the same frame multiple times, the GPU instructs the display control module to replay a previously-transmitted frame. During a refresh cycle in which the display control module is replaying captured content, the GPU omits accessing memory to retrieve and resend the frame that is being replayed, and instead sends only invalid data and GPU timing information so that the display control module remains synchronized with the GPU.

Abstract: A GPU is generally configured to detect changes in the rate of frame generation that can result from, for example, changes in the complexity of the frames being generated. In response to detecting the change in the rate of frame generation, the GPU identifies a corresponding change in the refresh rate that would be required to fully synchronize the refresh rate with the rate of frame generation. If the change in the refresh rate falls outside the boundaries of a specified or dynamically generated window, the GPU limits the change in refresh rate to the corresponding boundary.

Abstract: Systems, apparatuses, and methods for implementing a single-stream foveal display transport are disclosed. A system includes a transmitter sending an image over a display transport as a sequence of equi-sized rectangles to a receiver coupled to a display. The receiver then scales up the rectangles with different scale factors to cover display areas of different sizes. The pixel density within a rectangular region is uniform and scaling factors can take on integer or non-integer values. The rectilinear grid arrangement of the image results in simplified scaling operations for the display. In another scenario, the image is transmitted as a set of horizontal bands of equal size. Within each band, the same horizontal amount of transmitted pixels are redistributed across multiple rectangular regions of varied scales. The display stream includes embedded information and the horizontal and/or vertical distribution and scaling of rectangular regions, which can be adjusted for each transmitted image.

Abstract: Methods and apparatus provide pixel information for display. In one example, the methods and apparatus map, using a computing device, pixel information of a virtual rendering surface to a physical curved display screen based on field-of-view point reference data and display curvature data of one or more curved displays using a non-constant scale ratio among a plurality of differing physical pixels in at least one row of a portion of the physical curved display screen. Display data is output based on the mapped pixel information for display to the one or more curved displays.

Abstract: Systems, apparatuses, and methods for implementing an effective electro-optical transfer function for limited luminance range displays are disclosed. A processor detects a request to generate pixel data for display. The processor also receives an indication of an effective luminance range of a target display. The processor encodes pixel data of an image or video frame into a format which matches the effective luminance range of the target display. In one implementation, the processor receives encoded pixel data in a first format, wherein the first format has unused output pixel values which map to luminance values outside of the effective luminance range of the target display. The processor converts the encoded pixel data from the first format into encoded pixel data of a second format which matches the effective luminance range of the target display. A decoder then decodes the encoded pixel data and drives the decoded pixel data to the target display.

Abstract: A virtualized DisplayPort (DP) configuration data (DPCD) for multi-stream transport (MST) logical DP end points and non-DP end points allows DPCD configuration for links within a DisplayPort topology which are not configurable using DPCD. A virtualized DPCD may configure a link to an internal display of a MST sink device or a non-DP display to receive data using a dynamic refresh rate (DRR), display stream compression (DSC), panel self-refresh (PSR) and other DPCD configurable features.

Abstract: A method and device for providing synchronized data output is provided. The method includes generating two data streams sending data to be presented in synchronization. Both streams are generated by the same processor-based device. The first data stream follows a first protocol and the second data stream follows a second (different) protocol. The processor of the processor-based device adjusts a data rate of the second data stream to cause a reduction in any timing offset between the streams.
