基于FPGA的7x7块交织器设计，程序分交织、解交织两部分，并在QUARTUS II 9.0 下仿真通过，内附模块详细端口说明及仿真分析文件。

书名：LDPC原理与应用。是国内第一本介绍用LDPC编、译码基本原理及应用技术的一本书。对用 vhdl 或verilog实现硬件编程LDPC的人开发无线通信是很好的资料(Title: LDPC Principles and Applications. Is the first book describes using LDPC Encoding and Decoding the basic principles and application of technology, a book. Right to use vhdl or verilog hardware programming LDPC people to achieve development of wireless communications is a very good information)

哈希算法FPGA实现代码，采用MD5算法，并给出了仿真波形。(MD5 hashing algorithm for FPGA implementation code)

verilog入门基础以及简单编程介绍，verilog是近几年发展迅速的一门硬件语言-Verilog entry basis, as well as introduce a simple programming, verilog in recent years the rapid development of a hardware language

说明：  PL 和 PS 的高效交互是 zynq 7000 soc 开发的重中之重，常常需要将 PL 端的大量数据实时送到 PS 端处理，或者将 PS 端处理结果实时送到 PL 端处理，但是各种协议非常麻烦，灵活性也比较差，直接通过 AXI 总线来读写 PS 端 ddr 的数据，这里面涉及到 AXI4 协议，vivado 的 FPGA 调试等。(The efficient interaction between PL and PS is the top priority of zynq 7000 SoC development. We often need to send a large amount of data from PL to PS for real-time processing, or send the processing results from PS to pl for real-time processing. In general, we will think of using DMA for processing, but various protocols are very troublesome and the flexibility is poor. This course explains how to use Axi directly Bus to read and write DDR data of PS terminal, which involves axi4 protocol, FPGA debugging of vivado, etc.)

基于单片机显示原理的IO和LED显示原理(Based on the principle of IO chip and LED display shows the principle)

This tutorial presents some basic concepts that can be helpful in debugging of application programs written in the Nios II assembly language, which run on Altera’s DE2 boards.

使用VERILOG开发时钟同步算法，能够从数据信号中提取时钟信息，(Clock synchronization algorithm using VERILOG developed to extract the clock from the data signal information,)

使用VHDL编写语言，巧妙的利用计数器和循环输出一个坐标系，由于VHDL出现负数比较麻烦，全部由正数代替，输出一个原点在中心，半径128的256×256的坐标。方便坐标变换以及用此坐标做算法。(Use of VHDL language, clever use of counter and loop outputs a coordinate system, because VHDL negative too much trouble, all replaced by a positive number, the output an origin at the center, radius 128 256 256 coordinates. Convenient coordinate transformation and coordinate to do with this algorithm.)

说明：  数电实验FPGA verilog代码，包括秒表、全加器、半加器等。(FPGA Verilog code for digital experiment)
