Abstract
A VGA controller using address translation logic to drive a dual scan LCD panel is disclosed. The address translation logic converts the display data into an interleaved format in the display buffer, allowing the VGA controller to simultaneously access the display data for both LCD inputs without the need for a separate half-frame buffer memory. Elimination of this half-frame buffer memory reduces system cost with no reduction in performance of the VGA controller.
