基数 4 蝴蝶算法的实现

基4的FFT正变换和反变换程序，速度特快，使用方法简单且在程序注解中标注。带有测试程序，且在多个项目中应用，正确性毋容置疑。(Rad4FFT 和 Rad4iFFT)

16*16点阵横向移动显示！采用QUARTUS II 9.0编译通过！(16* 16 dot matrix display lateral movement! Compiled by using QUARTUS II 9.0!)

说明：  简单uart，verilog语言编写，已经经过测试，有需要的可以看看(Simple uart, Verilog language, has been tested, you can see if you need it)

曼彻斯特编码技术用电压的变化表示0和1。规定在每个码元中间发生跳变。高→ 低的跳变表示0，低→ 高的跳变表示为1。每个码元中间都要发生跳变，接收端可将此变化提取出来作为同步信号，使接收端的时钟与发送设备的时钟保持一致-Manchester coding techniques that use voltage changes in 0 and 1. Provisions in the middle of each symbol hopping happen. High → low hopping express 0, low → high jump for the express one. Symbol between each transition must happen, this change in the receiver can be extracted as a synchronization signal to the receiving end of the clock and send the equipment to maintain the same clock
