Abstract
An integrated circuit includes a display sub-system that has a plurality of image processing resources and control logic. The image processing resources include a plurality of image processing pipelines configured to operate in parallel, overlay logic coupled to receive image data from the plurality of image processing pipelines, and an image output port coupled to an output of the overlay logic with image data outputs configured to couple to one or more display devices. The control logic is dynamically configurable to assign each of the image processing resources to a selected one of a first control port and a second control port. The first control port is configured to be controlled exclusively by a first processor and the second control port is configured to be controlled exclusively by a second processor.
