一个用VHDL完成的8位数显的16进制的频率计

实现DE2_115开发板上配套的500万像素cmos摄像头捕捉到的画面显示在VGA上(DE2_115 development board supporting 5,000,000 pixels cmos camera to capture the screen display in VGA)

可以实现对任意波形分任意频，分频加减通过按键实现。-Can be achieved for any arbitrary waveform at frequency, frequency addition and subtraction through the keys to achieve.

通过VERILOG编写的AD9516时钟芯片SPI配置代码(CONGIGURE THE ad9516)

把指定的噪声叠加到信号上去.有标准噪声库NOISEX-92，其中带有白噪声、办公室噪声、工厂噪声、汽车噪声、坦克噪声等等，在信号处理中往往需要把库中的噪声叠加到信号中去，而噪声的采样频率与纯信号的采样频率往往不一致，需要采样频率的校准。 (The specified noise superimposed to the signal up. Standard noise library NOISEX-92, with white noise, office noise, factory noise, car noise, tank noise in the signal processing often requires noise to be superimposed in the library The signal to noise of the sampling frequency and pure signal sampling frequency is often inconsistent sampling frequency of calibration.)

此代码能够使得键盘控制液晶，实时的进行书写，按下Backspace清屏(This code enables the keyboard to control the LCD, in real-time writing, press Backspace clear the screen)

IT8051，增强版的T51，兼容DW8051核的多数端口，IO需要扩展后使用
