ALTERA 的关于对SDRAM控制器操作的verilog相关程序，很不错绝对值得借鉴。...

本书从电子技术和通信系统的角度讲解gps接收机的设计开发原理，其内容集中在用户终端，即接收机的设计原理和软件实现上。全书分为两大部分，第一部分为理论篇，第二部分为实现篇。理论篇首先对导航的基本目的进行了阐述，并由一个浅显的二维导航系统对导航信号的特点进行了推导，随后阐述了gps信号格式，同时对于直接影响接收机性能的射频前端部分做了理论分析；实现篇主要对本书实现的软件gps接收机的系统实现和源代码进行了讲解，同时作为总结，将信号处理的结果和有意义的中间变量以图示的方式给出，可以使读者有一个感性的认识，同时提升学习兴趣。. 本书适合从事卫星导航接收机研发的技术人员和卫星通信接收机研究的研究人员，尤其是从事北斗系统研发的专业人员、cdma通信系统研发人员，以及通信电子类专业的高年级本科生和研究生阅读，既可作为教学培训的教材，也可作为相关专业工程技术人员的参考资料。(This book explains the design and development principle of the GPS receiver from the perspective of electronic technology and communication system. Its content focuses on the design principle and software implementation of the user terminal, that is, the receiver. The whole book is divided into two parts. The first part is the theoretical part and the second part is the realization part. Firstly, the basic purpose of navigation is expounded, and the characteristics of navigation signal are deduced by a simple two-dimensional navigation system. Then, the format of GPS signal is expounded. At the same time, the front-end part of radio frequency which directly affects the performance of the receiver is theoretically analyzed.)

QuartusII8.0 Unix 和Linux按照指南-QuartusII8.0 Unix and Linux in accordance with the Guide

连乘,乘法可以用简单的for循环，我这里用的是移位寄存器来做，而且是用来两个移位寄存器(this is a tool that function is multiplay,it use a special way to do multiplay .it will teach you the how to use labview )

除法器,可以很好的实现VHDL除法器的功能对于初学者有很大帮助. -Divider can be very good VHDL divider realize the function of great help for beginners.

说明：  libero soc工程，实现通过串口接收到单字节数据后并返回发送给上位机(Libero SOC project, which realizes receiving single byte data through serial port and sending it back to host computer)

该代码是基于verilog 实现的代码，可以用于对接受1080P的LVDS视频数据并处理后显示到各种规格的LCD屏幕上，且支持从FLASH中读取BMP的图片数据并实时显示到LCS屏幕(The code is based on the code verilog achieve, it can be used for receiving LVDS 1080P video and data processing displayed on a variety of LCD screen, and support for reading data the FLASH BMP images and real-time display to the LCS screen)
