The Invention This invention is directed to a circuit and method for converting high resolution display data to a format suitable for display on a display device of lower resolution. Only a portion of the full high resolution image can be displayed on the display device of lower resolution. Memory accesses to areas which fall outside the range of applicable data for display on the lower resolution display device are selectively blocked. Representative claims 1 and 3 are reproduced below: 1. A circuit for providing automatic virtual display panning for driving VGA display data on a lower resolution display comprising, in combination: frame buffer memory means for storing a full resolution VGA image; display means coupled to said frame buffer memory means and having a resolution less than the resolution of said frame buffer memory means for providing a display; VGA controller means for transferring display data in claims contained in the brief is correct. Note that Amendment C cancels claim 5. We consider Amendment C as having been entered. -2-Page: Previous 1 2 3 4 5 6 7 8 9 10 NextLast modified: November 3, 2007
