An electronic device includes a display panel and image processing circuitry. The image processing circuitry receives input image data corresponding to an image to display on the display panel, modifies the input image data by executing a first context task (e.g., lower priority task), and receives a context switch request. The image processing circuitry also pauses modification of the input image data by pausing execution of the first context task and then switches to modifying the input image data by executing a second context task (e.g., higher priority task).

Transitions between monitor configurations may be streamlined by minimizing the tearing down and recreating of render targets and primary frame buffers associated with the monitors. In at least one example, the techniques described herein include identifying at least one render target in a first monitor configuration that is also in a second monitor configuration. In response to identifying the at least one render target in the first monitor configuration that is also in the second monitor configuration, the techniques herein describe maintaining the at least one render target during a transition between the first monitor configuration to second monitor configuration.

System and method of dynamically adjusting a frame buffer resolution. An average frame rate is dynamically computed based on the frame rates with respect to rendering a sequence of previous frames to a frame buffer. The frame rates may vary with the processing load of an associated graphics processor. A target scaling factor for frame buffer resolution is computed based upon the dynamic average frame rate and a desired frame rate. The current scaling factor of frame buffer resolution for rendering a respective frame data of a sequence of frame data to the frame buffer is adjusted incrementally to reach the target scaling factor. Accordingly, frame resolutions for rendering the sequence of frame data to the frame buffer are incrementally adjusted based on corresponding current scaling factors.

Graphical user interface (GUI) based systems and methods are disclosed for regionizing full-size process plant displays for rendering on mobile user interface devices. A regionizer application receives a full-size process plant display that graphically represents at least a portion of a process plant that includes graphic representations of a plurality of process plant entities. The regionizer app determines display region(s) of the full-size process plant display that define corresponding view portions of the full-size process plant display. The display regions are transmitted to a mobile user interface device for rendering by a mobile display navigation app. The GUI based systems and methods can also automatically detect graphical process control loop display portions within full-size process plant displays for rendering on mobile user interface devices. The GUI based systems and methods can further refactor full-size process plant displays at various zoom and detail levels for visualization on mobile user interface devices.

Disclosed is a payload mapper including N mapper(s), each of which includes a controller, multiple mapping circuits, an output control circuit, and a storage circuit. The controller includes: a decoding circuit receiving a first-format signal and decoding at least a part of this signal to find out the type of a control signal relating to the first-format signal; and a conversion control circuit generating a selecting signal according to the type of the control signal to choose one of the mapping circuits. The mapping circuits receive the first-format signal and selecting signal, and the selected mapping circuit converts the first-format signal into a second-format signal according to the selecting signal. The output control circuit is coupled to the mapping circuits and outputs at least a part of the second-format signal as an effective output signal. The storage circuit temporarily stores the effective output signal and then outputs it.
