i2c代码（简单读写1字节数据）

OPSK调制解调。代码思路很清晰，也很干净(Modulation demodulation OPSK. The code ideas very clear, and very clean)

本设计基于RS232进行了一个串口模块的设计，另外把一个FIFO加入其中，使得串口可以通过先进先出的模式进行数据的传输。

DES加密算法的VHDL实现,采用流水线技术实现(The VHDL implement of DES encrypt algorithmic)

说明：  In the data management system a significant role of the Data link layer is to convert the unreliable physical link between reader and tag into a reliable link. Therefore, the RFID system employs the Cyclic Redundancy Check (CRC) as an error detection scheme. In addition for reader to communicate with the multiple tags, an anti-collision technique is required. The technique is to coordinate the communication between the reader and the tags. The common deterministic anti-collision techniques are based on the Tree algorithm such as the Binary Tree and the Query Tree algorithms.

说明：  本文档对LTE进行了详细的介绍，是一本LTE入门的好书(This document is a detailed introduction to LTE, is a good book to get started with LTE)

VHDL code for 32 byte RAM

在学习verilog 中与遇到一些列问题的整理。(this Documentation is about the problem about verilog which is meeted when i was learn FPGA)

说明：  用Verilog编写的简单的运算单元（ALU），可实现加、减、与、或、异或、非、左、右移等功能(Verilog prepared with simple arithmetic unit (ALU), can be add, subtract, and, or, exclusive-OR, non-, left, and other functions shifted to right)

这是一本FPGA仿真验证的经典丛书，可以从中学习到如何编写系统的testbench,也可以是IC设计中FPGA原型验证编写系统及testbench的经典书籍。((Kluwer) Writing Testbenches Functional Verification of HDL Models.pdf)

资源描述基于fpga的串口通信，采用verilog语言，实验开发板与pc机之间的串口通信
