dds ad9910配置的verilog hdl程序，模块化设计，输入待配置的数据，字长，启动信号，即可自动产生时序，完成一次配置，模块还有done握手信号，方便用户调用时，反复多次配置。-dds ad9910 configuration verilog hdl program, modular design, the input data to be configured, word length, the start signal, the timing can be automatical

基于AD9910的Verilog程序，实现QPSK调制，只要再加少量代码就可实现8PSK调制-Based on Verilog AD9910 procedure, realization of QPSK modulation, just add a small amount of code can achieve 8PSK modulation
