VHDL语言实现VGA的显示彩条横条九宫格的功能。(VGA display color of the VHDL language bar Jiugongge function.)

说明：  32位/33M 从模式(target)PCI接口参考设计，Lattice提供。由于PCI时序较复杂，此设计仅能供参考(32/route from the model (target) PCI reference design, Lattice provided. Because PCI timing more complicated, and the design for reference only)

verilog编写的QPSK发射机的ＦＰＧＡ部分，已经过验证，完全达到要求。调制矢量误差４％(QPSK transmitter verilog prepared by the FPGA portion, has been proven, fully meet the requirements. Modulation vector error of 4 )

pcf8563，在quartusII下VERILOG编写的数字时钟程序，8位数码管显示(pcf8563, written in quartusII VERILOG digital clock program, eight digital display)

多频信号通过低通滤波器，使用Verilog语言进行设计，多频信号是正弦信号。

连乘,乘法可以用简单的for循环，我这里用的是移位寄存器来做，而且是用来两个移位寄存器(this is a tool that function is multiplay,it use a special way to do multiplay .it will teach you the how to use labview )

VHDL 的100例程代码，能够使你熟练掌握VHDL语言的编写(100 routines of VHDL code, enabling you to master the preparation of the VHDL language)
