软件无线电处理平台网络接口的设计

Design for Network Interface of Software Radio Processing Platform

在简要描述通用软件无线电处理平台系统结构的基础上,设计了基于高速微控制器DS80C411的网络接口,详细介绍网络接口的硬件和软件实现,其中包括DS80C411端的固件程序、主机端界面程序和FPGA端的接口程序编写。通过网络接口用户可以远程读写处理平台上FPGA的内部RAM,在实际使用中增强了系统的灵活性。目前此设计经过测试,已成功应用于项目中。

This paper briefly describes the systematic structure of the general software radio processing platform. On this basis, the network interface based on the high speed microcontroller DS80C411 is designed, and the detailed realization of the hardware and software discussed, including the program in the DS80C411, PC and FPGA. Users can remotely access the internal RAM of FPGA in the processing platform. In the project, the network interface has enhanced the flexibility of the system. Now this design is tested and used in the project successfully.
