发明名称 Apparatus for extending windows using Z buffer memory
摘要 A computer system which has a display memory for storing information to be presented on an output display, and a full screen bitmapped window identification memory for storing information regarding window position on an output display, and uses circuitry for comparing incoming information with information stored in the window identification memory to determine whether the incoming information should appear in a particular window of the output display, and also includes a second full screen bitmapped memory normally utilized for storing information indicative of other than window position on an output display and utilizes circuitry for selectively storing information in the second memory regarding window position on the output display when additional windows are required.
