Abstract

A stand-alone graphics workstation including a digital computer host and a graphics processing subsystem is disclosed. Address data relating to the graphics subsystem components is mapped into the host system virtual memory. The application processes residing in the host are thereby able to communicate directly with the graphics subsystem components, as, e.g. the structure memory, without the need of a direct memory access hardware arrangement or device drivers.
