ABSTRACT:
For use in a computer graphics apparatus, a data management system drives a multiple-window dynamic display. The display is formed by areas, e.g. pixels, and windows are variously defined in a display by assigning window codes to groups of areas. Image data for each area provided from a picture system is selectively registered in an image frame buffer in accordance with the defined windows. Valid data binary signals, designating currently valid image data in the image frame buffer are registered in three valid data buffers. The image data for each area is provided for a display from the selectively registered signals in the image frame buffer under control of the window codes and the valid data binary signals. Techniques are thus available for rapidly swapping portions of the frame buffer and selectively clearing and loading the image frame buffer. Areas not specified by signals from the image frame buffer are treated as background and driven with an appropriate display.
