摘要
依托TM S320DM 642芯片在数字视频监控系统中的应用,对该芯片的网络功能模块的构成和功能进行了详细的分析.并以在DM 642开发板上实现M PEG-2实时网络视频传输的实例,给出了基于DSP/B IO S和NDK的嵌入式网络操作系统网络接入的硬件和软件设计方法.经实验研究结果证明是合理和有效的.
The paper analyses the latest research and development in the embedded-net technique and discusses the design way of the single chip network access. After introducing chip＇s construction and function of TMS320DM642＇s network module in detail,an approach of network access based on the single DSP chip is presented. The hardware and software implementation way based on DSP/BIOS and network developer＇s kit （it is abbreviated in NDK） embedded operating system network access are given by giving an example of video transmission on MPEG-2 real-time network. And it is realized in the DM642 EVM. The experiment result shows that the approach is effective. The paper has the reference functions in realizing the single chip network access.
