GRAPHIC CONTROLLER FOR STANDARDIZED BUS

This device is used for controlling colour monitors with analogous inlets and a high-resolution capacity. It enhances the opportunities for processing and exchange of the information displayed on its monitor, while the magnification and displacement of the image on the monitor is done via an apparatus. The controller contains a micro-processor bloc (5), connected by an interface bloc (1) to a standardized highway, and by a first buffer of monitor memory (9) to a sectioned monitor memory (20), to which, via a second buffer of a monitor memory (19), the data and address outlets of a graphic microprocessor (13) are linked, and, via a selection bus (21) to a decoder for the current working or the page displayed (15). The outlets of the decoder (and part of the bloc outlets for apparatus magnification and displacement of the image (14)) are connected to the microprocessor bloc (5), while another part of the outlets are connected to the graphic microprocessor (13) and the second buffer for monitor memory. The address outlets of the sectioned monitor memory are supplied via displacing registers (24) to a colour-table memory bloc (16), whose other outlets are connected to the micro-processor bloc, and its outlets connected, via a bloc for digital-analogous transformation of RGB-colour signals (26), to the inlets for colour information of a colour monitor (27).
