摘　　要：针对ARM+DSP异构双核硬件的复杂性,在达芬奇开发平台的基础上,介绍了多线程的实时应用,分析了达芬奇应用程序的一般开发实现流程和两个终端通过SIP服务器构建的流程,进行相关协议栈的移植和SIP服务器的搭建,并最终实现在局域网内由SIP服务器进行控制的音视频的多媒体通信系统。Considering the complexity of DaVinci development platform based on ARM -F DSP heterogeneous dual-core hardware, this article introduces the multi-threaded real-time applications, analyses the general development procedure of DaVinci applications and the two terminals built by SIP server, transplants the relevant protocol stacks and builds the SIP server, and ultimately implements audio and video multimedia communication systems controlled by the SIP server in the LAN environment.
