Abstract
A graphics system may include a frame buffer, a processing device coupled to access data in the frame buffer, a frame buffer interface coupled to the frame buffer, and an output controller configured to assert a request for display data to provide to a display device. The frame buffer interface may receive the request for display data from the output controller and delay providing the request for display data to the frame buffer if the processing device is currently requesting access to a portion of the frame buffer targeted by the request for display data. For example, if the frame buffer includes several memory banks and the request for display data targets a first bank, the frame buffer interface may delay providing the request for display data to the frame buffer if the processing device is currently requesting access to the first bank.
