For a display device having a plurality of subpixels disposed in an active area of a display panel, a method for processing a compensation data of the display device may include reconfiguring an order of unit patches having the compensation data so that the unit patches having similar reference values are positioned adjacent to each other when the compensation data are compressed. The disclosed method can improve the compression process efficiency where a compression loss can be reduced, and an effect of an image quality improvement using the compensation data can be enhanced.

This disclosure provides systems, devices, apparatus and methods, including computer programs encoded on storage media, for reducing a DPU transfer time to compensate for a delayed GPU render time. After completion of rendering a second frame that follows a first frame, a frame processor determines whether the first frame is currently transferring to a display panel or has already been transferred to the display panel. At least one clock is used with a first set of clock speeds when the first frame is determined to be currently transferring and used with a second set of clock speeds when the first frame is determined to have already been transferred, the second set of clock speeds being faster than the first set of clock speeds. After completion of the transfer of the first frame, the second frame is transferred based on the set of clock speeds.

A video display includes a display panel with gate drivers and source drivers. Each of said the source drivers is arranged to receive a discrete-time continuous-amplitude signal representing a video stream over a transmission medium and to decode the signal using demodulation to produce a plurality of samples for output on outputs of the source drivers. At least one of the source drivers is arranged to extract a gate driver timing control signal from the signal and to output the gate driver control signal to the gate drivers in order to synchronize the gate drivers with outputs of the source drives, whereby the video stream is displayed on the display panel of the display unit.

Systems, apparatuses, and methods for implementing fine-grain power management for virtual reality (VR) systems are disclosed. A VR compositor monitors workload tasks while rendering and displaying content of a VR application. The VR compositor determines the priorities of different tasks of a given VR frame and cause power states to be assigned to processing units to match the priorities of the tasks being performed. For example, if a first task within a first frame period is assigned a high priority, a processing unit executing the task operates at a relatively high power performance state when performing the first task. If a second task within the first frame period is assigned a low priority, the processing unit operates at a relatively low power performance state when performing the second task. By implementing fine-grain power management in a VR environment, the likelihood of the processing unit suffering a thermal event or impaired performance is reduced.

Methods and apparatus relating to an adaptive multibit bus for energy optimization are described. In an embodiment, a 1-bit interconnect of a processor is caused to select between a plurality of operational modes. The plurality of operational modes comprises a first mode and a second mode. The first mode causes transmission of a single bit over the 1-bit interconnect at a first frequency and the second mode causes transmission of a plurality of bits over the 1-bit interconnect at a second frequency based at least in part on a determination that an operating voltage of the 1-bit interconnect is at a high voltage level and that the second frequency is lower than the first frequency. Other embodiments are also disclosed and claimed.
