Abstract

Abstract The invention embraces improvements applicable to the electronic systems for generating graphics and sounds, such as for video game apparatus, of the kind comprising a master microprocessor connected to a data sup­port memory unit and to control means, at least one slave microprocessor managing the video information of image planes, and at least one slave microprocessor handling audio information. In a first aspect of the invention, the video information management is performed by a plurality of mi­croprocessors, everyone of each independently deals with a corresponding image plane, thus speeding up screen display changes. Another feature of the invention contemplates the use of a read and write magnetic memory device for general information, such as a floppy disk unit, combined with read and write solid state memories of the system and control means of the master microprocessor for placing in­formations of the magnetic memory in the solid state memory to be acceded by the screen and sound managing microprocessors.
