LCD图形显示代码，已调试过，可以运行成功(LCD graphics display code has been debugged, you can run successfully)

说明：  ad 9226 数据采集芯片的 FPGA 实现，FPGA 对数据的采集准确，通过仿真和实测(The FPGA implementation of ad9226 data acquisition chip,FPGA data acquisition accuracy, through simulation and measurement.)

本文阐述了设计的 4 位携带看前方 adder.this 加法器是比较会波及进位加法器的高速度。

this program is a simulation for Aloha

借助于实际计算除法的经验，比如11（1011）除以2（0010）（注：以二进制的方式进行），我们首先会比较被除数的最高位是否大于等于除数2，显然该例中1小于10，那么商0，再向下一位看，此时为10，与除数相等，商1余数为0；继续看被除数后一位为1小于除数2，商0，再向下一位看，此时为10，与除数相等，商1余数为1；这样连续比较四次便得到了最后的结果。商为5（0101），余数为1；

找到这本书的完整版了。呵呵，贴出来和大家共享。这是本好书，我买了一本作为Verilog的参考书。这本书语法部分集中，便于查阅，此外讲了很多实用的设计思想。最重要的是本书薄，可以完整看完。强烈推荐。 （如果只是查阅，电子版就可以，如要完整学习，建议还是买纸质版的）(Find the full version of this book. I posted and share. This is a good book, I bought a reference book as Verilog. Syntax in this book section focuses on ease of reference, in addition to speaking a lot of useful design ideas. The most important thing is that the book is thin, you can complete reading. Highly recommended. (If you only access the electronic version to complete learning, suggestions or to buy the paper version))

该程序实现最小频移键控信号的调制解调，经测试无误。(The program implements minimum shift keying signal modulation and demodulation, tested and correct.)

1。源文件保存在src目录，QII的工程文件保存在Proj目录； 2。程序实现的功能是在VGA显示器上显示彩色条纹，共8种颜色， 可以使用嵌入式逻辑分析仪观测信号； 3。modelsim仿真文件在proj--simulation--modelsim中(1. The source file is saved in the src directory QII project file is saved in the directory Proj 2. The functionality of the program is displayed on a VGA monitor color stripes, 8 colors, you can use the embedded logic analyzer observed signals 3. the modelsim simulation files in the proj- simulation- modelsim)

说明：  数字信号处理的FPGA实现(第4版)的配套源码，极具参考价值。(The source code of the realization of digital signal processing on FPGA (4th edition) is of great reference value.)

数字钟，数字电子技术课程设计常用内容，基于basys3平台(Digital clock, digital electronic technology curriculum design commonly used, based on the basys3 platform)
