至于FSK调制原理就不多说了，这里做的一个实验是二进制频移键控。发送一组码元，通过响应的键控电路监测是发1还是发0然后选择频率控制正余弦电路波形。...

4个7段lcd同时显示的程序，已经在digilent的nexy2板上通过验证，非常好用易懂，适合初学者学习-display 4 leds

六层的电梯控制系统 用VHDL描述同时还附有系统仿真图形

实用的程序代码，希望对大家有用，已经调试通过-Practical program code, in the hope that useful to everybody, has debugging through

开发系统上采用的时钟信号的频率是20MHz，可分别设计计数器对其计数，包括计秒、分、小时、日、周、月以及年等。在每一级上显示输出，这样就构成了一个电子日历和时钟的模型。为了可以随意调整计数值，还应包含设定计数初值的电路-Development system using the clock signal frequency is 20MHz, the design can be counter to its count, including seconds, minutes, hours, days, weeks, months and years. At every level to show the output, thus constitutes an electronic calendar and clock models. Can also adjust the order value, should also be included in setting the initial count circuit

this is code verilog

千兆以太网设计，包括组包解包，可以实现大数据传输功能。(Unpack the gigabit Ethernet is designed, including group package, can realize large data transfer function.)

基于Verilog HDL的完整数字跑表工程，在试验机台上运行验证通过了的。 用8位7段数码管分别显示微妙，秒，分。 有开始，暂停，复位功能。 学习VerilogHDL的经典例子，添加了显示功能。-Complete Verilog HDL-based digital stopwatch works in the test machine is running verify pass the platform. With 8-bit 7-segment digital tube showed the delicate, seconds, minutes. Has started, pause, reset. Learning VerilogHDL classic example of adding a display.

用Verilog语言实现汉明编码，很粗燥，是大三的时候做的(With the Verilog language Hamming code, it is rough dry, a junior at the time to do)

VHDL的初学者可以参考此VHDL加法器，相信会给你带来不小的收获-VHDL beginner can refer to the VHDL adder, I believe will bring you not a small harvest

本文介绍了汉明编码与译码通过FPGA器件来实现，介绍了使用VHDL语言编程的基本算法！-This article describes the Hamming encoding and decoding through the FPGA device to implement, introduced the use of VHDL programming language is the basic algorithm!
