摘要
在图像视频实时处理领域,针对传统的专用处理系统开发难度大、开发周期长的缺点,提出了一种RTX(Real-Time Extension For Windows)加Windows的通用系统架构.采用了PCI作为传输总线,使用DMA加中断的数据传输模式,保证了数据的实时传输性能;处理算法工作在RTX下,设计了RTX和Windows的进程间通信功能,保证了系统处理的实时性能同时还减轻了开发的难度,缩短了系统的开发周期.最后通过实验进一步证明了把视频图像的实时处理任务移植到该系统下是可行的.
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.
