VHDL实现SPI接口转I2c接口的源代码，可以直接调用

小波包分解，重构轴承振动信号，Hilbert包络，FFT进行频谱分析，以获得轴承故障频率。(Wavelet packet decomposition, reconstruction of bearing vibration signal, Hilbert envelope, FFT spectrum analysis to obtain the bearing fault frequencies.)

eda的入门学习课件，老师不错，内容页挺好的(eda learning files)

DS18B20温度传感器，用verilog语言实现(DS18B20 temperature sensor, with the verilog language)

verilog编写的流水线模块-Verilog modules prepared by the Pipeline

说明：  基于IIC协议的EEPROM模型，可实现串行数据转并行数据，并行数据转串行数据，分为EEPROM模块，EEPROM_WR模块，signal模块，Top模块(The EEPROM model based on IIC protocol can convert serial data to parallel data and parallel data to serial data. It is divided into EEPROM module and EEPROM module_ WR module, signal module, top module)

这是一个最最常用的用vhdl写的状态机，几乎哪儿都用得到(a very good state machine)

QAM调制，基于FPGA的实现，包含有乘法器模块、升降余弦滤波器模块、QAM序列生成模块(QAM modulator,the implementation based on FPGA,include MUL、FIRCOS and QAM generate)

SDRAM驱动器，自己项目利用的，已经经过实际验证(sdram controller)

基于System Generator的图像处理工程,多媒体处理FPGA实现的源码,图像边缘提取(System Generator based image processing engineering, multimedia processing FPGA implementation source code, image edge extraction)

cordic 算法知道正弦和余弦值，求反正切，即角度。(The CORDIC algorithm knows sine and cosine values and asks for inverse tangent, that is, angle.)
