EXCD-1 可编程片上系统 实验例程 EDK部分 功能：使用SDK 工具和CHIPSCOPE 进行软硬件协同调试-CHIPSCOPE to use the SDK tools and hardware and software co-debugging

echo_server,基于xlinx的sdk编程，采用lwip完成了tcpip协议，包含完整的源代码。-echo_server, based xlinx the sdk programming, using lwip completed tcpip agreement contains the complete source code.

socket编程例程，在xilinx的sdk环境下实现，简单易懂，可作为设计参考-socket programming routines to achieve in the xilinx sdk environment, easy to understand, can be used as a reference design
