利用fpga实现的DDS，可输出正弦波，输出频率可调

build synthesizer on a de2 dev fpga board

说明：  matlab代码，利用Farrow结构设计分数延时滤波器，滤波器阶数和个数可分别进行设置，利用最大最小准则近似(Matlab code, using Farrow structure design fractional delay filter, filter order and number can be set separately, using the maximum and minimum criterion approximation.)

基于ISP的交通灯设计，实现了各路状态转换、警察控制、行人请求功能。(ISP traffic light design, to achieve the brightest state transitions, police control, pedestrian request feature.)

使用VHDL进行分频器设计，主要是一些分频的东西，整数分频，小数分频，奇次分频和偶次分频-Divider using VHDL to design, mainly because some sub-band stuff, integer divider, fractional-N, odd and even sub-sub-sub-sub-band frequency

实验用16位全加器的VHDL代码，适合初学者学习，数电学习的好工具。 (Experiment with 16-bit full adder VHDL code for beginners to learn, a good tool to learn a few power.)

代码基于VHDL语言的个文化代码有用的但是可能有错误下在是倾销心-VHDL code based on the cultural code useful but may be under the wrong heart is dumping
