基于verilog的串口收发协议

描述

基于FIPS 180-4标准的SHA-1算法的verilog HDL实现，分模块分别实现(FIPS 180-4 standard SHA-1 algorithm-based verilog HDL sub-modules, respectively, to achieve)

说明：  使用FPGA实现RGB图像转灰度图像的算法，下载入自己的电路板可直接将摄像头拍摄到的图像实时转换成灰度图像(FPGA is used to realize the algorithm of transforming RGB image into gray image. The image captured by the camera can be converted into gray image in real time by downloading it into its own circuit board)

URAT VHDL程序与仿真 URAT the VHDL program and Simulation (URAT the VHDL program and Simulation )

说明：  内部含3个模块，使用DDS产生200k与500k的正弦波，两者相加后过数字低通滤波（通带0-200k，阻带400k以上），并将波形输出，实测FFT分析中看不到500k分量。其中数字滤波器采用MATLAB设计（FIR+等波纹，阻带衰减-80dB）(There are three modules in the system. DDS is used to generate 200K and 500K sine waves. After adding the two modules, the digital low-pass filter (passband 0-200k, stopband above 400k) is used, and the waveform is output. 500K component can not be seen in the actual FFT analysis. The digital filter is designed by MATLAB (FIR + equal ripple, stopband attenuation - 80dB))

实现输入一正弦波和噪声的叠加，介绍详细欢迎下载(The input of a superposition of sine wave and noise introduced in detail)

i2c_master_bfm，可以直接使用实现i2c master的仿真功能

EMIF接口调试代码，使用的是Verilog语言，FPGA与DSP通信，测试成功(EMIF interface debugging code that USES the Verilog language, FPGA and DSP communication, testing success)

说明：  2018全国大学生FPGA创新设计大赛南京总决赛封闭测试题目，以及自己编写的verilog和testbench，欢迎学习借鉴(The closed test topic of the 2018 National Undergraduate FPGA innovation design competition Nanjing finals, as well as Verilog and testbench compiled by ourselves, are welcome to learn)

说明：  利用fpga实现gmsk的调制并仿真，全部代码(Fpga implements gmsk)
