摘要
采用TI公司的TMS320C5402和DaVinci系列TMS320DM6437双DSP芯片为主要处理器,构建了一个基于DSP/BIOS的视频图像采集处理平台。从功能的角度将系统划分为视频采集任务、视频算法处理任务、数据通信任务和人机交互任务4个相对独立的线程,这4个线程在实时操作系统DSP/BIOS不同优先级的调度下有序地工作。测试结果表明,整个系统运行稳定,实时性较高。
The system uses double DSP chips of TMS320C5402 and the a series of DaVinci TMS320DM6437 as the processor to build the software platform of video and image collection process platform. From the angle of function,the system is divided into four relatively independent thread, which are image collection, image processing, data communication and human-computer interac- tion. These tasks operate according the previously configured priority scheduling in DSP/BIOS. Test results show that the whole sys- tem has good stability and rapid real-time characteristics.
