Abstract: This paper designed a new system for real-time video processing by using RTX and Windows,solving the difficult development and long development cycle problems which exist in the routine embedded special processing platform.To achieve the real-time transfer performance,we use the PCI-Bus working in the DMA and interrupt mode;meantime,algorithms perform in the RTX environment which supplies the real-time processing ability.Since the RTX works together with Windows system,the proposed framework can greatly augment the power for human-machine interaction.Furthermore,experimental results show that it is feasible to transfer the real-time video processing tasks to this system from the routine embedded system.
