Video signal generation using a new interfacing technique for computer system

Abstract

A new architecture for generating video signal using computer and microprocessor-based system is presented. This architecture uses a new interfacing technique for the data transfer from the microprocessor-based system to our video memory. This technique is based on the use of extended physical addressing or fast physical addressing which is aimed to reduce the use of physical addresses in microprocessor-based system. Furthermore, it improves the data transfer speed. The proposed system combines a software/hardware solution to obtain the above advantages and uses digital-to-analog conversion (DAC) in the output stage.
