用VHDL实现十六位移位乘法器 才有移位相加法来实现

清华大学sdr项目，网口代码。Verilog编写。很实用。希望大家喜欢。(Tsinghua University sdr project, network interface code. Verilog preparation. Very practical. Hope you like it.)

verilog2000更新部分，请对照前一个标准。加入了一些新的支持-verilog2000 update, a former control standards. The inclusion of some new support

说明：  Verilog 入门,如果你要很了解Verilog你不用先谖完一本厚厚的书还弄不清楚Verilog到底在干啥事,这份资料有助於快速了斛Verilog(Verilog Basic, If you try very hard to understand verilog by read a thick book, try read this first you will get a quick understanding of verlog.)

适合DE2板，能够在板子上的液晶显示器上实现时钟功能。-for Dictyophora board, in the way of achieving LCD clock function.

AD转换的Matlab程序，将输入电压转换成时间(脉冲宽度信号)或频率(脉冲频率)，然后由定时器/计数器获得数字值(AD conversion of the Matlab program, the input voltage is converted into a time (pulse width signal) or a frequency (pulse frequency), and then to obtain a digital value by the timer/counter)

基于vhdl可用的数字频率计，误差较小，精准度较高。文件中还包含了与arm的通信模块、

我的学习经验，一种自适应分频及分频方法的实现，很好用的哦-my learning experience, an adaptive frequency-frequency method and the realization of the good, oh

程序实现自动售货机的核心功能，设有3种价格的商品，可选择数量，有找钱功能。-program vending machine at the core function, with three kinds of commodity prices, the number of choice, having to function.

基于fpga的DDS程序 可输出正弦波 方波 三角波 锯齿波(DDS program based on FPGA can output sinusoidal square wave triangular wave sawtooth wave)

I2C verilog 源代码 非常好的代码，大家可以-I2C verilog source code for a very good code, we can
