摘要
达芬奇处理器是TI公司新推出的高性能嵌入式片上系统,在安防领域有着广泛的应用前景。提出了一种将DM6446处理器与LCD显示器通过数字接口实现显示的设计方案,并结合DM6446视频后端处理子系统的工作原理和时序要求,实现了DM6446到LCD的数字动态视频、汉字显示、OSD等功能。实际测试结果表明,软硬件工作良好,可供其它嵌入式产品的开发作为参考。
Based on the Davinci technology, TI is offering the next level of SOC and embedded development tools and support with high performance. The application of Davinci processor is more widely and popularly on the security and protection fields. Digitalvideo displaying system based on DM6446 and LCD is designed, the basic principle and timing sequence of video processing back end （VPBE） is researched, the function of digital dynamic video, Chinese characters displaying, OSD and so on are successful debugged. As the result, the hardware and software worked well on the target board. It is propitious to design other embedded systems.
