利用verilog实现对SD卡的控制，可以实现对SD卡的读写。(Verilog SD)

DDS在现在运用月来越广泛，在相对带宽、频率转换时间、相位连续性、正交输出、高分辨力以及集成化等方面都远远超过了传统频率合成技术所能达到的水平，为系统提供了优于模拟信号源的性能。利用DDS技术可以很方便地实现多种信号。在FPGA上实现的DDS-DDS now to the use of more extensive relative bandwidth, frequency conversion time, phase continuity, quadrature output, high-resolution and integration, and other aspects far more than the traditional frequency synthesizer technology can achieve the level To provide a superior analog signal source performance. DDS technology can be used very easily to a variety of signal. FPGA Implementation of DDS
