modsim仿真必备，可以帮助你解决很多你对软件不熟悉的问题！...

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)

有一个 8 位全加器 VHDL 代码。我测试该代码在协同，看到了这段代码的工作。

HDMI做为视频输出输入接口已经广泛使用很长时间，主要通过TMDS差分编码传输。本实验通过在HDMI屏幕上显示彩条和输入输出环通实验，来练习视频的时序和视频颜色的表示，为后面视频处理实验做个基础。(HDMI as video output input interface has been widely used for a long time, mainly through TMDS differential coding transmission. In this experiment, by displaying color bars and input/output loop experiments on HDMI screen, video timing sequence and video color representation are practiced to lay a foundation for video processing experiments later)

时间设置 可以作为设计中的一个小模块进行使用 方便快捷(time setting)

VHDL_COUNTING 与 4 使脉冲和使用 3 按钮了，下来，停止 （Mạch đếm với 4 xung ENA sử dụng 3 nút nhấn lên，xuống và dừng lại）

简易双口ram，使用两个ram ip core，一个写的同时另一个读，并且包含按键使能和数码管以及流水灯显示(Simple dual-port ram, two ram the ip core, a write while another read, and contains buttons to enable digital pipe and the water light show)

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,

modelsim仿真，大量vhdl程序，验证，很有价值！(The ModelSim Simulation, a large number of VHDL procedures, validation, great value!)

数控分频器的设计 数控分频器的功能就是当在输入端给定不同输入数据时，将对输入的时钟信号有不同的分频比，例3的数控分频器就是用计数值可并行预置的加法计数器设计完成的，方法是将计数溢出位与预置数加载输入信号相接即可。(NC NC divider divider design of its function is when the input given different input data, input the clock signal will have different frequency than, for example 3 is to use the NC prescaler count preset value of the adder parallel counter design is completed, the method is to count the number of overflow bit with preset load to the input signal phase.)

六十进制计数器用于计数等操作，代码的实现方式很简单(Six decimal counter for counting operation, the code is very simple implementations)
