Abstract
A method and apparatus for processing video data at various optimum operating rates is accomplished by a video graphics circuit that includes a video graphics module, a buffer and a memory interface, where the video graphics module, which may be a graphical user interface (GUI), is operated at a first clock rate and the memory interface is operated at a second clock rate. In this circuit, the buffer temporarily stores data, such that communications with the memory interface are done at the second clock rate while communications with the video graphics module are done at the fist clock rate.
