fft变换三个中的一个（站长：三个代码算一个）

实现一个循环冗余码,是老师给的例子，别的同学已经验证-a cycle ruduandency code

用Verilog实现1602的配置及功能。正确编译与实现(Realized by Verilog 1602 configurations and functions. Compilation and implementation of the right)

运用vhdl程序设计语言进行ppm设计，ppm 设计在vhdl语言中非常常用，运用已经越来越广泛。-use vhdl program design language ppm design, vhdl ppm design in a very common language, has become increasingly widespread use.

基于Verilog的数码管模拟扫描程序，分为两种显示方式，一种是数码管逐个显示，另一个是所有数码管一起显示。-Verilog-based digital control analog scanning procedures, two types of display, a digital control-by-show, and the other is with all digital tube display.

自己根据xapp1052修改的源代码，已经编译成功，并应用在开发板上。(According xapp1052 own modified source code has been successfully compiled and used in the development board.)

串行流水线格式:使用COrdic 算法计算反正切:向量模式下求角度 16bit :数据全部补码格式 (Serial line format: Use COrdic algorithm arctangent: seeking angle vector mode 16bit: full complement data format)

QuartusII多路选择器,数字电路环境，大三EDA技术实验(Quartus,chosen conductos in matheathics field)

数控分频器的设计 数控分频器的功能就是当在输入端给定不同输入数据时，将对输入的时钟信号有不同的分频比，例3的数控分频器就是用计数值可并行预置的加法计数器设计完成的，方法是将计数溢出位与预置数加载输入信号相接即可。(NC NC divider divider design of its function is when the input given different input data, input the clock signal will have different frequency than, for example 3 is to use the NC prescaler count preset value of the adder parallel counter design is completed, the method is to count the number of overflow bit with preset load to the input signal phase.)

 交通灯控制器控制红（r）、绿（g）、黄（y）三种不同颜色的交通灯，这三种不同颜色灯的亮、灭分别由三个定时器（timer1、timer2、timer3）控制；  当某个定时器工作时，它所控制的交通灯亮，直到设定的定时时间到（该定时器状态由’0’变’1’），交通灯跳转到另一种状态；  clk是脉冲控制端（图中未标出）；reset是异步复位端，复位状态为红色交通灯亮；  输出端r、g、y分别表示三种颜色交通灯的亮、灭状态。 ( traffic light controller control red (R), green (g), yellow (y) three different colors of traffic lights, three different colors of bright lights, off by three timer (Timer1, Timer2, Timer3 ) control  When a timer work, it controls the traffic lights, until the set timing (the timer status ' 0 ' for ' 1' ), traffic lights Jump to another state  clk is the pulse control terminal (not shown) reset is asynchronous reset terminal, the reset state for the red traffic lights  output terminal r, g, y represent the three colors of traffic lights bright, the off state.)
