GPS 码 nco 码跟踪环累加模块设计

RS232协议的fpga实现，工业应用中可以灵活的应用ps2协议设备，并且可以快速修改，本协议是采用verilog实现的。

小波变换的VHDL代码，内带正变换逆变换的测试文件。(Wavelet transform VHDL code, with a positive transformation within the inverse transform of the test file.)

本代码实现一个fir滤波器，结合matlab对数据进行进行验证，最后用modesim对编写的代码进行仿真，最终用matlab和fpga实现一个功能正常的fir低通滤波器，这里附有源代码，并且用verilog代码编写，具有很大的参考作用对于刚学习fpga的朋友，希望你们能真正的对所学的东西感兴趣，这个是我上传代码的初衷，希望你们学业进步，继续做一个对技术有信心的人才。

该例子是基于sopc的IIC总线设计完整设计，分为硬件和软件部分，软件部分是用c语言编写的。该项目是个以完成的项目，据有较高的参考和经济价值。该例子是原来做过的项目。 整个项目是在Quartus II 7.0和nios IDE环境下开发。 (This example is based on the IIC bus design sopc complete design, divided into hardware and software, the software part is written in c language. The project is to complete the project, according to the reference and a higher economic value. The example is a project originally done. The whole project is in the Quartus II 7.0 and the nios IDE development environment.)

数字频率计，测量范围0-1GHZ,测周测频自动转换，精度极高，花了很长时间，不过还是有一点点小问题，有待改进.(Digital frequency meter, range 0-1GHZ, automatic conversion measured weekly frequency measurement, high precision, took a long time, but still a little small problems to be improved.)

The ElectricTM VLSI Design System is an open-source Electronic Design Automation (EDA) system that can handle many forms of circuit design, including: * Custom IC layout * Schematic Capture (digital and analog) * Textual Languages such as VHDL and Verilog (The ElectricTM VLSI Design System is an open-source Electronic Design Automation (EDA) system that can handle many forms of circuit design, including:* Custom IC layout* Schematic Capture (digital and analog)* Textual Languages such as VHDL and Verilog)

quartus verilog 逻辑分析仪， 检测数字信号（与示波器检测模拟信号对应），vga显示输出。经过本人调试可用。

用Verilog HDL编写的PID程序代码，成功调试，运行良好。(The source code of PID in Verilog HDL.Simulation was successful.)

一款非常实用的8051IPcore,本人现在做soc的控制部分就是它。(A very useful 8051IPcore, I now control part of the soc is doing it.)
