自编的64B/66B编码程序，下次上传解码程序。(the 64B/66B coding process is written by myself, i will upload the decoding process next time.)

使用nios2点亮一个led灯，使用软件quartus13.0，开发板de2-115(nios2 led quartus13.0 de2-115)

说明：  DDR（双速率）SDRAM控制器参考设计verilog代码，可以直接用的，很好的(DDR (double rate) SDRAM controller reference design Verilog code, can be directly used, very good)

一个用verilog实现的五子棋程序，用在fpga上，连接显示器，可选择与电脑对战或是双人对战，按wsad控制方向，回车控制落子，程序会自动判断输赢并显示结果(A 331 procedures implemented by verilog, used in fpga, connect the monitor, you can choose to play against the computer or a double play, press wsad control the direction, carriage control Lazi, the program will automatically determine the winners and losers and display the results)

介绍了在数字语音通信中, 利用在系统可编程技术和复杂可编程逻辑器件CPLD, 实现了数字语音的复接和分接 对于其中的单稳态电路的数字化和数字锁相环提取位同步信号也进行了详细的设计说明。实际应用结果表明, 系统工作稳 定可靠, 设计是成功的。(Describes the digital voice communications, the use of in-system programmable technical and complex programmable logic device CPLD, to achieve the digital voice multiplexer and demultiplexer for the single steady state in which the digital circuit and digital phase locked loop extraction bit synchronization signals are also carried out a detailed design specification. The practical application results show that the system works stable and reliable design is successful.)
