波形产生器：用VHDL编写的波形产生器程序

例如分频器，alu，ram的verilog实现(The implementation of divider, alu, ram etc. in verilog)

用VHDL编写的计算器，能实现简单的加减乘除四则运算

此示例是8051核加频率计的联合设计,带有8051IP核资料-This example is the 8051 nuclear increase the frequency of joint design, with the nuclear information 8051IP

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,

数字示波器实验，利用AD、DA和VGA三个外设来实现简易示波器，DA外设发送正弦波给AD外设，AD外设解析成数字信号将数据送给VGA外设进行显示。在VGA上可以看到DA外设发送的波形、波形频率和波形峰峰值。(In the experiment of digital oscilloscope, AD, DA and VGA are used to realize simple oscilloscope. DA peripheral transmits sine wave to AD peripheral. AD peripheral resolves into digital signal and sends data to VGA peripheral for display. The waveform, waveform frequency and peak value of DA peripheral can be seen on VGA.)
