huffman transform in vhdl language

说明：  PF6182是一款很好的DC-DC同步降压IC。输出电压可调整，电流达2A。非常好用(PF6182 is a good DC-DC synchronous buck IC. Adjustable output voltage and current up to 2A. Very easy to use)

ModelSim的波形比较的功能可以将当前仿真与一个参考数据（WLF文件）进行比较，比较的结果可以在波形窗口或者列表窗口中查看，也可以将比较的结果生成一个文本文件-ModelSim waveform can be compared to the current functional simulation with a reference (WLF paper ), the results can be compared in the waveform window or window List View, it will also compare the results generate a text file

计算机组成原理课程设计代码，课程设计，计组(Computer organization principle curriculum design code, curriculum design, group calculation)

这是我准备电子设计大赛时，用VHDL写的一个自动打铃系统，很好的学习资料。-This is when I am going to Electronic Design Contest, use VHDL to write an automatic bell playing system, a very good learning materials.

说明：  用FPGA进行等精度频率和相位差测量的程序，本程序是在EPEC6Q240C8下的程序(Carried out with the FPGA such as the frequency and phase measurement precision of the procedure, this procedure was the procedure under the EPEC6Q240C8)

内容有VHDL语法总结及相应的实例应用，每个程序我都亲自试过，特别适合初学VHDL的同学们。常用的程序有 设计一个M序列发生器，M序列为“11110101”、 设计一个彩灯控制器，彩灯共有16个，每次顺序点亮相邻的四个彩灯，如此循环执行，循环的方向可以控制。设计一个跑马灯控制器。一共有8个彩灯，编号为LED0~LED7，点亮方式为：先从左往右顺序点亮，然后从右往左，如此循环往复等等。这些都是我在考试前熬夜总结的，很有用。如果配合开发板用的话，那就更好了 ( VHDL syntax summary content and the appropriate application instance, every program I have personally tried, especially for students of beginner VHDL. Common program has designed a sequence generator M, the M series is 11110101 , a lantern controller design, a total of 16 lights, each sequence of four adjacent lights lit, so the cycle execution cycle direction can be controlled. Marquee design a controller. A total of eight lights, numbered LED0 ~ LED7, the lighting way: first left to right order of light, and then right to left, so the cycle and so on. These are all I stay up all night before the exam summary, very useful. When combined with the development board, then so much the better )

红外接收处理，根据外部波形记录波形的高低电平时间，从而得到波形数据。(Infrared receiver processing, according to the external waveform waveform record high and low times, resulting waveform data.)
