基于fpga和xinlinx ise的usb端口vhdl程序，希望对你有所帮助！

常用的锁相环技术，此程序是我在设计高频电路中运用的，具体见程序，经调试无问题-Commonly used phase-locked loop technology, this program is in the design I used in high-frequency circuits, see the specific procedures, no problem by debugging

说明：  该代码，只用了硬件描述语言Verilog在完成对SD卡控制器的编写，经济实用(The code, only the hardware description language Verilog in the completion of the SD card controller to prepare, economical and practical)

ANALYSIS OF D-FLIPFLOPS

采用Xilinx公司的Spartan6 FPGA设计PCI Express的详细参考资料(Xilinx' s PCI Express, Spartan6 FPGA design, detailed reference information)

本文介绍了使用verilog语言进行硬件设计的一些基本技巧-This paper describes the use of Verilog hardware design language, the basic skills

本练习的目的是构建和使用计数器。所设计的电路将在计算机上实现

基于matlab和vhdl的通信原理gmsk调制算法，主要包括GMSK相位路径的计算,GMSK眼图的仿真以验证相位计算的正确性,正余弦表的量化及bin文件的生成,以及用VHDL硬件语言所描述的基于EPM7128的地址逻辑.(Matlab and vhdl based on the principle gmsk Modulation of communication, including GMSK phase path calculation, GMSK eye diagrams of the simulation to verify the correctness of the phase calculation, is the cosine table generating quantitative and bin files, and using VHDL hardware description language logic based on the address of EPM7128.)

实现QPSK系统的调制解调仿真，基带成形滤波器采用升余弦滚降滤波器，将仿真的误码率与理论误码率作了比较(Implement QPSK modulation and demodulation simulation system, the baseband shaping filter using Raised Cosine filter will BER simulation were compared with the theoretical BER)

Farrow 滤波器设计经典文章，作者是：FM.Gardner，farrow滤波器设计的始祖，经典值得推荐！（两篇文章）(Farrow filter design classic article, the author is: FM.Gardner, farrow filter design ancestor, classic worth recommending! (Two articles))
