Data processing installation for window-oriented raster graphic system - uses additional data preparation elements for increased processing speed

摘要

A data processing system for window-oriented raster-graphic systems has a graphic processor in which graphic objects are processed and converted into data which are stored in an on-screen memory. The stored data are passed to a monitor via a digital-to-analogue converter. For rapid data transfer, graphical objects to be processed by the graphic processor and already in the form of data are prepared by devices (2-4) connected after the on-screen memory. ADVANTAGE - Overcomes disadvantages of conventional systems.
