DUC数字上变频设计

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)

关于I2C总线协议的verilog代码，里面包括了3个verilog代码(I2C bus protocol verilog code, which includes three verilog code)

基于FPGA实现蜂鸣器播放音乐的功能 使用芯片为EP2C8Q208C8N,使用普通蜂鸣器，由于频率不同可实现放歌功能，本例设计的是《友谊地久天长》，使用Verilog语言编程，本例子有工程文件、仿真、波形，经过测试可以使用。(Play music based on FPGA buzzer functions using chip EP2C8Q208C8N, using ordinary buzzer, since the frequency of different functions can be realized sing, in this case the design is " Auld Lang Syne" , using Verilog language programming, this project examples files, simulation, waveform, tested can be used.)

Altera FPGA  NIOS II 通过W5500芯片完成网络TCP/IP通讯。

本书共由三篇组成。其中第一篇由第1~3章组成，介绍PCI总线的基础知识。第二篇 由第4~13章组成，介绍PCIExpress总线的相关概念。第二篇的内容以第一篇为基础。(This book comprises a total of three components. The first chapter from the first 1-3 chapters, introduces the basics of the PCI bus. Second by the first 4 to 13 chapters, introduces concepts related PCIExpress bus. The contents of the first to second basis.)

64点的 FFT verilog,它是串行计算的，工作频率不到100M，计算速率很高，里面的层次很清晰。(64-point FFT verilog serial computing, the operating frequency of less than 100M, the calculated rate is high, the level inside is very clear.)

C++获取CPU占用率，一个类和一个头文件(Gets the CPU Use rate)

通信控制中常用的脉冲宽度检测程序，VHDL模块化编成实现（原创）(communication control used in pulse width detection procedures, VHDL modular organization to achieve (original))

verilog 的东西好好用的呢，那是verilog 学习者的必备东西哦(verilog things properly used it, it is an essential learners verilog things oh)
