全功能I2C接口
软件操作I2C的过程如下：
1)
配置要控制器输出的字节内容（地址0xC0~0xD5）。如写命令：{7位地址+RW位}{命令字}{长度（LGTH）}{命令数据}{check}。注意，40G光模块要求的最后校验字节需要软件计算好。

AES加密算法verilog源码
AES加密算法verilog源码
This project is the hardware implementation of the
Advanced Encryption Standard with a key size of 128 bits.
The implementation adheres to the FIPS-197 document which explains the same.The core can do both encryption as well as decryption.The documents aes_arch.doc and aes_tb_readme.txt give further details of the rtl implementation and test bench respectively. This code was written originally with 128 bit ports for both input and key but later converted to 64 bits each to save on i/o pins. It can be reverted back easily if one just changes the port widths and dispenses with the load signal in the top module and making approriate changes in process where load is used.Synthesis results have been included for Xilinx Spartan-3 device.The directory structure of the project is as under-
