Abstract

Disclosed is a device that adds the capability of priority and windowing to a system that supports transparency and the concept of a "start point" for a display frame buffer. The combination of these four capabilities allow: the formation and change of composite pictures on a display screen in real time; use and manipulation of different forms of display data independently.
