这是我准备电子设计大赛时，用VHDL写的一个自动打铃系统，很好的学习资料。...

说明：  本工程使用A7系列FPGA产生DDS，用DAC0832进行正弦电压输出(In this project, A7 series FPGA is used to generate DDS, and DAC0832 is used for sinusoidal voltage output)

Verilog 编写的串口通信模块 带测试代码(Verilog prepared by the serial communication module with a test code)

高通滤波器的仿真（由matlab和simulink两种方法实现）源文件以及图片示例(Simulation of the high-pass filter (implemented by the two methods matlab and simulink) source files as well as images example)

test bench for alu 6 functions

自己写的FPGA实现电子琴的VHDL程序，曲目是两只老虎，用到一些模块，和片内存储间，呵呵(FPGA realization of his keyboard to write the VHDL program, tracks are two tigers, a number of modules used, and on-chip storage room, huh, huh)

its a Fifo BASED design i also Interface DAC2904

FPGA控制RS232来实现串口通信，非常好的串口程序。(FPGA control RS232 serial communication to achieve very good serial procedures.)

TDM，就是时分复用。本程序完成4通道，没通道最多32路64K信号的交换，就是说可以完成32x4个电话信号交换(TDM, is time-division multiplexing. The process is complete 4-channel, no channel up to 64K 32 to exchange signals, that can be done 32x4 telephone signal exchange)

Aurora协议是一款高带宽、低成本、可扩展、框架简洁、适合点对点串行数据传输的协议。(Aurora protocol is a high-bandwidth, low-cost, scalable, simple framework for point to point serial data transfer protocol.)

最新的CCSDS高光谱图像压缩算法标准的FPGA实现，用VHDL实现的。可参考。绝对物有所值，希望对你的设计有所帮助!
