IIC总线协议，VHDL语言编写，可以直接使用

该程序是整个OFDM接收机的程序，希望对做这方面的朋友用些帮助，也希望朋友们和我一起探讨OFDM收发信机。(The program is the whole OFDM receiver process, hope to do in this area with some friends to help and also hope that friends and I explore OFDM transceiver.)

viterbi译码器的IP核，可以直接编译使用-viterbi decoder IP core, the compiler can directly use

基于VHDL实现加扰器解扰器的设计，与仿真。(VHDL-based scrambler descrambler design and simulation.)

用Quartus II开发的一个十进制计数器，包括仿真波形，下载文件，是完整工程。(With the Quartus II development of a decimal counter, including the simulation waveform, download files, is the complete project.)

altera 公司的15IP源码 亲自测试还不错 有DIV, CONTER-ALTERA the 15IP source personally tests are also good DIV, CONTER

PLL是数字锁相环设计源程序, 其中, Fi是输入频率(接收数据), Fo(Q5)是本地输出频率. 目的是从输入数据中提取时钟信号(Q5), 其频率与数据速率一致, 时钟上升沿锁定在数据的上升和下降沿上；顶层文件是PLL.GDF-digital phase-locked loop PLL design source, in which Fi is the input frequency (receive data), Fo (Q5) is the local output frequency. Objective is to extract data input clock signal (Q5), its frequency and data rate line, the clock rising edge of the lock data the rising and falling edge; top-level document is PLL.GDF

512阶高速FIR成型滤波器，四相位复用，树形加法和多级流水线结构。(512-order high-speed FIR shaping filter, four-phase re-use, tree addition and multi-stage pipeline structure.)

这是一个nios工程，控制TFT液晶屏的程序。FPGA平台用Verilog HDL语言编写的，MCU软核程序有C语言编写。通过这一个完成的工程，你就会明白SOPC的一些实现方法。(This is a nios engineering, control TFT LCD screen program. The FPGA platform Verilog HDL language preparation with the nuclear program has a soft, MCU written in C language. Through this a complete project, you will understand some of the SOPC methods of realization. )
