用VHDL langhantdma

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)

DDS的频率转换可以以近似认为是即时的，这是因为它的相位序列在时间上是离散的，在频率控制字改变之后，要经过一个时钟周期之后才能按照新的相位增量增加，所以也可以说它的频率转换时间就是频率控制字的传输时间，-DDS frequency conversion can be considered similar to real-time, this is because it is the phase sequence in time is discrete, in the frequency control word change after one clock cycle to go through before a new phase in accordance with the incremental increase, so it can be said of the frequency switching time is the frequency control word transmission time,
