基于FPGA驱动高速AD/DA

主要用于信道编码，可以防止相位的翻转，计算码元之间的相位变化以后，做差分传输，接收端根据前一码元的相位进行解差分。

实现dsp与fpga的emif的verilog异步实现，可实现异步读写以及相应功能模块控制，文件中包含仿真后的波形图形以及仿真测试程序，运行环境quartus ii11.0，仿真环境mmodelsim se 6.5d(Achieve dsp and fpga verilog asynchronous implementation of the emif, enabling asynchronous reading and writing as well as the corresponding function module control, the document contains graphics, and after the simulation waveform simulation testing procedures, operating environment quartus ii11.0, simulation environment mmodelsim se 6.5d)

说明：  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.)
