4dbpsk系统的设计实现源码，几个朋友用一个假期的时间协作完成，功能非常好...

异步串口通信口在FPGA实现，功能有（1）串行数据接收的同步控制；（2） 串行数据发送的同步控制-asynchronous serial communication port of the FPGA, function (1) serial data receiver synchronization control; (2) the transmission of serial data synchronization control

实现4种常见波形正弦、三角、锯齿、方波（A、B）的频率、幅度可控输出（方波 --A的占空比也是可控的），可以存储任意波形特征数据并能重现该波形，还可完成 --各种波形的线形叠加输出。 (Achieve the four kinds of common sine wave, triangle, sawtooth, square wave (A, B) the frequency and amplitude controlled output (square wave- A duty cycle is controlled), can store arbitrary waveform feature data and can to reproduce the waveform, it can perform- all kinds of linear superposition of the output waveform.)

this Code is in verilog HDL. This Code is for piplined processor with 4 opcode. this will work in three cycle latch, decode and exicute.. test bench for xilinx ise is laos given
