Verilog code to calculate Sobel

实现fpga上交通灯的设计，可以在开发板上实现红绿灯(Design of traffic lights on FPGA)

这个程序是基于等精度测频原理的频率计，用VHDL语言实现，频率测量测量范围1~9999；用4位带小数点数码管显示其频率，并且具有超量程、欠量程提示功能。-This procedure is based on the principle of frequency measurement accuracy, such as the frequency meter, using VHDL language, frequency measurement range 1 ~ 9999 with four decimal places with the frequency of the digital display and has a super-range, less range prompts.

用Verilog实现汉明码编码，经测试可正确使用，代码简洁(Verilog with Hamming code encoding, the test can be used correctly, the code is simple)

VHDL Bible. It is a must read for any front end vlsi designer.

这是很全的标准库啊，不是1164.vhd，都是一些加，乘，除，平方等操作的包来的．-This is the standard for the whole ah, not 1164.vhd are some increases, multiplication, addition, operational square packages to come.

这是一个vhdl代码的进位选择加法器及其工作100%。

说明：  编码方式为213的Viterbi卷积码编码器和译码器的FPGA的实现，包含整个QuartusＩＩ的工程文件，解码方式为寄存器交换法(Encoding for the 213 convolutional code encoder and Viterbi decoder FPGA realization of the project file that contains the entire QuartusII, decoding method for the register exchange)

一个任意整数分频程序,采用VHDL语言编写，编译通过-An arbitrary integer frequency procedure for the VHDL language, the compiler through

说明：  verilog语言书写，单周期CPU源码(single period CPU)
