摘　　要：采用双Nios II架构的可编程片上系统(System On Programmable Chip,SOPC)的设计方法,进行了系统规划,分析了SOPC定制、内存芯片共享、数据搬移、通信与互斥的实现,介绍了软件设计调试的特点。工程应用表明,双软核良好地实现了并行处理与协同工作,成倍地提高了工作效率。Embedded network server is the performance key of the network video surveillance system. Its tasks are heavy and real-time capability is highly required. A method to design the SOPC with dual Nios Ⅱ architecture is presented in this paper. The system is outlined.The means to customize, the sharing of the memory chip, the transference of the image data and the implementation of the synchronization between the dual CPUs are analyzed. Moreover, the specialties of software design and debugging are introduced. The result of applying the method in project indicates that the dual CPUs run simultaneously and cooperate well, and the system efficiency is remarkably improved.
