摘　　要：一种基于龙芯3A处理器的信号处理平台,该平台由两片龙芯3A处理器通过HT0总线互联而成,对外提供了两路x4 RapidIO高速串行通道和两路千兆以太网通道.详细分析了该平台软件移植中的难点和关键技术点,深入分析了"风河"公司最新推出的支持多核架构的vxWorks 6.8实时操作系统.列出了该平台的实测数据,与国内外信号处理平台进行了对比,并得出结论.The design of a signal process platform based on loongson 3A is introduced. The platform is constituted by two loongson 3A chips which are connected by HT0 interface. The platform supplies two RapidIO channels and two Gigabit Ethernet channels. The article analyses the difficult problem of software transplant of the platform and the vxWorks 6.80S deeply. At last, the article lists the testing data and compares to the data of the other platforms and draws a conclusion.
