基于FPGA的会议系统通信协议设计和实现

Design and Realization of a National Conference System Communication Protocol Based on FPGA

结合工程应用需要,介绍了基于FPGA的国际会议系统通信协议设计,使用VHDL语言编程,并在Xilinx公司的Spartan-3系列FPGA上实现。在接收端使用Xilinx的DCM倍频本地时钟来同步接收信号,简化了传输线路。通过对地址查询的特殊处理可保证单机能动态加入网络,提高了系统的灵活性。设计采用低成本的FPGA实现,具有成本低、性能高、灵活性强、速度快等特点。通过工程应用证明了设计是正确可行的。

In the paper, we discuss the design and realization of a National Conference System Communication Protocol which based on FPGA. The protocol which implemented with a Xilinx＇s Spartan - 3 FPGA chip is described in VHDL. In the receive side by using Xilinx＇s DCM local time is multiplied to synchronize reveived data, which simplifies transmission line. With special disposing of address enquiring,terminal can add to the system. Based on a low cost FPGA,the design present the characteristic of strong flexibility, high speed,great capability and so on. It is proved practical by the engineering application.
