说明：  本程序为自己毕业设计用，可通过数据控制VGA显示动态竖彩条，为了使大家容易理解此程序，我对其中关键处作了详细说明，希望对FPGA爱好者和FPGA初学者有用!
(The graduate program designed for their own use, data control via dynamic vertical color VGA display section, in order for you easy to understand this process, key Department of which I explained in detail, I hope fans of the FPGA be useful!)
