摘要
针对高分辨率灰度图像及其复杂的处理算法,选择双DSP板连接系统进行图像和算法处理。基于TMS320DM642视频口的特点,通过硬件连接和软件设置,设计实现通过视频口在两块DSP板之间进行BT656_8BIT数据流的实时传输,实验结果显示该方法稳定可靠,在多DSP间的数据传输同样有适用性。
In view of the complex algorithms for high resolution gray level image processing, two DSP boards are connected as a system for processing. Real-time transporting BT656_8BIT data flow between two actual DSP boards is successfully implemented through connection of hardware and configuration of software based on the feature of video ports TMS320DM642, which verifies the stability, reliability and general compatibility for transporting data flow during multiple DSP.
