这是一个用VHDL语言描述的I2C自动配置模块，使用了来自opencores.org的I2C核，已在altera的cyclone芯片上调试通过-This is a VHDL language used to describe auto-configuration of the I2C module, the use of the I2C from opencores.org nucleus, the cyclone in the altera-chip debugging through

说明：  ds1302时钟驱动程序，已在quartus上验证可以是直接使用(DS1302 clock driver, which has been verified on quartus, can be used directly)

实现多路可变时分复用，包括复接器，解复接，比特同步，帧同步，分频器(Implement multi-channel variable time division multiplexing, including multiplexer, demultiplexing, bit synchronization, frame synchronization, frequency divider)

FFT implementation using C program

一个三分频verilog模块，可以用来学习基本结构。(A three points frequency verilog module can be used to study the basic structure.)

本人写的数字锁相环，有模拟数据，学习锁相环很好的材料。参考书“数字锁相环路原理与应用”编写。-I write the digital phase-locked loop, have simulated data, a good phase-locked loop learning materials. Reference book

verilog 编写的比较最大值最小值得的程序，而且能够求出最大最小值在ram中存储的位置，测试通过下载即用(Comparison of the maximum write verilog smallest worthwhile program, and minimum and maximum values ​ ​ can be obtained is stored in ram position, the test that is used by downloading)
