60进制减法 相比较 代码效率高 可以进行级联

基于FPGA的DDS程序代码，实现的功能强大可以输正弦波，三角波，方波等波形，并且频率可以调节。实现对应的功能强大。(FPGA-based DDS program code can achieve powerful output sine wave, triangle wave, square wave waveform and frequency can be adjusted. Implement corresponding powerful.)

说明：  一个交通灯设计,简单的实现，没有添加其他的显示管(Traffic Light System)

modelsim仿真，大量vhdl程序，验证，很有价值！(The ModelSim Simulation, a large number of VHDL procedures, validation, great value!)

vhdl testbentch 编写模板。非常实用-vhdl testbentch prepared templates. Useful

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.)

此程序基于ADC0809,它是CMOS的8位A/D转换器，片内有8路模拟开关，可控制8个模拟量中的一个进入转换器中。-Connection between ADC 0809, it was the eight CMOS A/D converters. Tablets containing eight analog switches, control eight of analog converters enter a Chinese.

例程是基于quartus的，FPGA通过EMIF给DSP发送数据，里面包含了一个简单的状态机和一个基于IP核的fifo，适合初学者(Routine is the FPGA to send data to the DSP via EMIF, which contains a simple state machine and an IP-based core fifo, suitable for beginners)

基于FPGA的SD卡音频播放器 经过调试可以直接用，音质很好有MP3的所有功能(FPGA-based audio player, SD card can be directly used after debugging, good sound quality with all the features of MP3)
