FPGA基于DDS数字信号发生器设计（方波、三角波、正弦波）频率可调，步进可调

8051Core的源代码，Verilog编写，包括ALU、存储器、SP、dptr等诸多模块，十分完整，已在Quartus上编译通过，确认无误。

自己编写的同步和异步FIFO的verilog代码，验证过，有可靠性(Verilog code of my own synchronous and asynchronous FIFO, verified,and reliable.)

实现QPSK系统的调制解调仿真，基带成形滤波器采用升余弦滚降滤波器，将仿真的误码率与理论误码率作了比较(Implement QPSK modulation and demodulation simulation system, the baseband shaping filter using Raised Cosine filter will BER simulation were compared with the theoretical BER)

实现LDVS接口数据接收 含有协议结构以及处理(lvds Verilog 512 frame)

BCH3.c,提供m<21以下的所有码长的BCH编解码模块。以供大家参考。谢谢(BCH encoder&decoder GF(2^m) m<21)

这是基于Nios II的12864液晶点亮程序，包含汉字、字符等(This is a program which is based on Nios II ,its function is light the 12864 LCD that including Chinese characters, characters)

控制电话信令 完成忙碌 等待 回铃音振铃等(Signaling complete control over telephone ring so busy waiting ringback tone)

基于DB8小波变换的verilog代码设计，支持Avalon总线(Verilog DB8 Wavelet Transform Based on code design, support Avalon bus)

通过FPGA驱动千兆以太网口，完成SPARTAN6上的UDP数据包闭环测试，即通过网口发送数据包到FPGA，FPGA内部将接收到的数据返回到PC机，建议测试之前添加ARP静态绑定，FGPA内部的IP以及MAC地址在ROM里的COE文档里可以看到，发送端添加了CRC以及整体CHECKSUM的计算(Driven by FPGA Gigabit Ethernet port, UDP SPARTAN6 data packet on the closed loop test, through the network to send data packets to FPGA, FPGA will receive the data back to the PC, the proposed test before adding ARP static binding, FGPA internal IP and MAC address in the COE document in the ROM where you can see, the sender adds CRC and CHECKSUM integral calculation)

本例程位于 VMD642_CPLD目录中。 使用 CPLD 实现辅助译码、LED 指示灯控制、看门狗等各种逻辑控制电路。源程序使 用 Verilog HDL书写，编译开发系统使用 Cypress公司的 Warp 6.3。(This routine is located VMD642_CPLD directory. Using CPLD implementation auxiliary decoding, LED indicator control, watchdog, and other logic control circuitry. Written using Verilog HDL source code, the compiler development system using Cypress' s Warp 6.3.)
