基于C6000 DSP NDK的组播网络设计与实现

Design and implementation of multicast network based on C6000 DSP NDK

随着系统应用的复杂化,很多情况下需要将相同数据分发至不同的使用终端,这也促进了网络传输组播模式的应用。基于实际应用需求,以TMS320C6455芯片为核心处理平台,利用TI公司DSPC6000平台上的NDK(Net Developer’s Kit)开发包,对Marvell公司的88E6060(SWITCH)芯片进行配置,实现了适用于多个终端进行组播方式网络通信的嵌入式系统设计。经过测试验证,该系统工作正常稳定,实现了百兆组播传输功能。

With the complication of systems, the same data needs to be transferred to different application terminals in the same time, which also promotes the multicast mode application of network. According to the application requirements, by taking TMS320C6455 as a core processing platform, the 88E6060 chip made by Marvell is configured with Net Developer＇s Kit on DSPC6000 platform to realize the design of the embedded system which is suitable for multi- terminals to execute the network communication in the muhicast mode. The test results show that the embedded system works stable. The 100M muhicast trans- mission function was realized.
