针对TI公司芯片TMS320DM6437硬件平台,在开源编码器X264基础上,基于TI公司提供的DSP/BIOS系统,宴现了多线程,具有视频采集、编码、传输、解码和显示功能的视频系统。实验结果表明,通过DSP/BIOS的襄时可伸缩性内核,合理设置各分任务线程之间的通信和调度机制,并利用实时分析和配置工具,合理配置代码和数据空间,可以实现整个系统的高速运行,并可以大大缩短系统的开发时间。
In this paper, according to the characteristics of TI's TMS320DM6437 platform, a video system is implemented based on an open source H.264 encoder X264. TI's DSP/BIOS system is used to speed up the development process. This muhithread video system implements video capture, video encode, transmission, video decode and video display. Experimental results show that, after making full use of DSP/BIOS system and setting up the thread schedule, the entire system can run at a high speed and the development time can be reduced significantly.
