Steuerschaltung fuer die Datenspeicherung in einem fenster-orientierten Rastergraphik-System

Data processing system for windows-oriented raster graphics systems comprising a graphics processor in which graphical objects are processed and transferred into a data volume, this being saved in an on-screen memory, and the saved data being displayed on a monitor via a DA converter, whereby, in order to speed up the data transmission of the graphical objects already presented in the form of a data volume to be processed by the graphics processor can be processed by devices (1, 2, 3, 4) downstream of the on-screen memory.
