Abstract
In accordance with one aspect, a display controller is included in a graphics processing unit. In some embodiments, the display controller includes a read memory requester configured to provide a data request to a source of image data, a data path configured to be coupled to the source of image data, an output coupled to the data path and a control unit in electrical communication with the read memory requester and the data path. In accordance with one embodiment, the output is configured to provide image data processed by the display controller and the control unit is configured to stop an output of image data processed by the display controller. In accordance with a further embodiment, the control unit includes a stop-output register configured to provide information employed by the control unit to stop the output of image data processed by the display controller.
