A new mixed software/hardware architecture is presented for the generation of video signals from a microprocessor system. This architecture uses fast physical addressing as a hardware interface for the transfer of data from the microprocessor system to the video memory of the system. The interface is based on the utilisation of a mixed software/hardware system and has three objectives. Firstly, the control of a relatively large video memory space while using a reduced range of the physical addressing zone of the microprocessor system. Secondly, the increase of the data transfer speed, and thirdly the possibility of a display conforming to different norms and standards.
