Multi-window display control system
First Claim
1. A multi-window display control system which is composed of a central processing unit, a main memory, a shared memory, an external memory, an input means, a display means and a display memory for storing a plurality of display data being overlapped and displayed, said system comprising:
- a display processing means for performing display processing of a plurality of display data;
a first save area installed on the display memory for temporarily saving overlapped data of the plurality of display data;
a second save area installed on the shared memory for temporarily saving overlapped data of the display data;
a third save area installed on the external memory for temporarily saving overlapped data of the plurality of display data;
a first control table installed on the main memory for controlling display position, mutual priority for display, and a save area during overlap, regarding each of a plurality of display data stored in the display memory,wherein said display processing means controls display of the plurality of display data using the first control table, the first, second and third save areas, and the display memory.

Abstract
A central processing unit, a main memory for storing graphic or character data, an external memory, an input device for inputting the graphic or character data, a shared memory for temporarily storing the graphic or character data read by the central processing unit, a display processing means for preparing a plurality of display data displayed on a display from the graphic or character data on the shared memory, and a display memory for storing the plurality of display data are connected to a bus. The display memory, the shared memory, and the external memory have first, second and third save areas for temporarily saving the overlapped display data when the plurality of display data are overlapped. The main memory is provided with a first control table for controlling display position, mutual priority for display, and a save area during overlap, regarding each of the plurality of display data stored in the display memory. The display processing means controls to display the plurality of display data on the display using the first table, the first, second and third save areas, and the display memory. In the first, second and third save areas, the first save area has highest priority and the third save area has lowest priority.
