摘　　要：NFS是一种比较成熟的分布式网络文件系统,为数据存储、管理提供了良好的解决方案,一般运行在通用计算机中。随着嵌入式系统资源的不断丰富,小型、便捷、易于扩展的NFS服务器对于嵌入式平台越来越重要。采用软硬件协同设计的方法,设计实现了一个基于FPGA平台的嵌入式NFS,包括NFS服务组件、文件系统、硬盘控制器等模块。前两个模块运行在FPGA内嵌Micro Blaze处理器上,后一个模块用硬件描述语言设计实现。对设计在Xilinx的XUPV5_LX110T开发平台进行了调试验证。NFS, which is a kind of relatively mature distributed network file system, provides a good solution for data storage and management, and usually runs in an all-purpose computer. As the resources of embedded system are continuously enriched, a small, convenient, and easy to expand NFS server becomes more and more important for embedded platforms. This paper adopts the co-design of hardware and software, designs and implements an embedded NFS server based on FPGA, which includes the NFS server component modules, file system modules, and hard disk control module. The first two modules run on the MicroBlaze processor embedded in FPGA, and the last module is designed and implemented with hardware description language. The whole design is debugged and verified on the platform of XUPV5_LX 110T of Xilinx.
