VHDL描述的时钟分频电路，用途广

改写四号中断的 自己编的，，，，，，求过啊！！！一个很简单的小程序(Rewrite the fourth interruption of their series,,,,,, begged ah! ! ! A very simple little program)

Quartus II软件设计数字电子钟，使用verilog语言编写各个 模块生成symbol files，再用原理图方式制作顶层文件。 完成的功能有：能够显示时、分、秒；具有清零，调节分钟的功能； 具有整点报时功能，声响电路发出叫声； (failed to translate)

基于System Generator的图像处理工程,多媒体处理FPGA实现的源码,图像增强处理,平滑,锐化,滤波(System Generator based image processing engineering, multimedia processing FPGA implementation source code, image enhancement, smoothing, sharpening, filtering)

在matlab仿真的基础上，用maxplus2实现等波纹法的程序代码(In matlab simulation, based on the use of such corrugated maxplus2 realize law code)

数控机床 多轴插补原理积分算法，实现s曲线加减速原理(Numerical control machine tool multi axis interpolation principle, integration algorithm, to achieve the S curve acceleration and deceleration principle)

基于FPGA的2FSK调制解调，里面有详细的工程说明，对于学习ISE软件和通信原理的知识很有帮助(FPGA based 2FSK modulation and demodulation, which contains detailed engineering instructions, for learning ISE software and communication principles of knowledge is very helpful.)

利用VHDL语言实现8位到32位的双向数据转换-use VHDL 8-32 two-way data conversion

PLL是数字锁相环设计源程序, 其中, Fi是输入频率(接收数据), 数字锁相技术在通信领域应用非常广泛，本例用VHDL描述了一个锁相环作为参考，源码已经调试过。编译器synplicty.Fo(Q5)是本地输出频率. 目的是从输入数据中提取时钟信号(Q5), 其频率与数据速率一致, 时钟上升沿锁定在数据的上升和下降沿上；顶层文件是PLL.GDF-digital phase-locked loop PLL design source, in which Fi is the input frequency (receive data), the digital technology in the field of communications is widely used, the cases described in VHDL as a PLL reference source has been tuned. Compiler synplicty.Fo (Q5) is the local output frequency. Objective is to extract data input clock signal (Q5), its frequency and data rate line, the clock rising edge of the data locked up and the descending; Top-level document is PLL.GDF

跑马灯（几个LED灯动态闪烁，产生特定方波信号如01010111要用到单个LED灯，请尝试修改paomadeng程序完成）、数码管显示（例如在三个数码管上显示“sos”）、蜂鸣器、LED点阵显示等程序，现在综合如下，其中xx是按键防抖模块，可以不加。
