摘要:

采用ADSP BF533DSP处理器设计并实现了基于IP网路的多媒体通信终端系统。终端的管理采用μCOS II实时嵌入式操作系统。在分析μCOS II操作系统特点的基础上,把LwIP协议栈移植到μCOS II上实现了网络接口。试验结果表明,该系统在局域网中多媒体信息的编码、传输是实时的。

Abstract:

A multimedia communication terminal based on ADSP-BF533 DSP processor and used in IP network was designed and implemented. μCOS-II embedded operation system was used in the system, with the transplantation of LwIP. The experiments show that by the multimedia communicaiton terminal, the coding and transportation of multimedia information can be realized in real time in LAN.
