Abstract
A computing system includes a display controller and a processing device external to the display controller. The display controller includes a content verification circuit configured to generate a derived value representing visual content of interest (COI) within an image frame for a region of interest (ROI) on at least one display device. The processing device includes an error-detection circuit configured to perform an error-detection process for the visual COI based on the derived value.
Claims20
A method, comprising:
- generating, at a display controller, a derived value representing visual content of interest (COI) within an image frame for a region of interest (ROI) on at least one display device;
- and
- responsive to sending the derived value from the display controller to a processing device that is external to the display controller and external to a display subsystem implementing the display controller, performing, at the processing device, an error-detection process for the visual COI based on the derived value.
A computing system, comprising:
- a display controller having a content verification circuit configured to generate a derived value representing visual content of interest (COI) within an image frame for a region of interest (ROI) on at least one display device;
- and
- a processing device external to the display controller and to a display subsystem implementing the display controller, the processing device having an error-detection circuit configured to perform an error-detection process for the visual COI based on the derived value received from the display controller.
A method, comprising:
- generating, by each virtual machine of a plurality of virtual machines, a set of image data to be presented on at least one display device associated with the virtual machine;
- generating, at a display controller for each set of image data, a derived value representing visual content of interest (COI) within the set of image data for a region of interest (ROI) on the at least one display device associated with the virtual machine that generated the set of image data;
- and
- performing an error-detection process for each visual COI based on the respective derived value.
