高速光纤通信中的CRC-32算法的研究与实现

CRC-32 algorithm in high-speed optical fiber communication Research and Implementation

循环冗余校验CRC广泛用于各种数字通信中用以提高传输数据的可靠性,是通信领域最为常用的一种校验算法。针对高速的光纤通信,给出了一种参数模型可设置的32位CRC用于其数据校验,采用VHDL语言对算法完成建模与实现,并以ALTERA公司开发的EDA工具QuartusII9.1作为编译、仿真平台进行了仿真验证。电路的综合仿真结果表明,该设计完全满足高速,大容量的光纤通信数据校验要求。

The cyclic redundancy check CRC is widely used inavariety of digital communication is the most commonly used inthe field of communicationin order to increasethereliability of data transmission.For high-speed fiber-optic communication, a parametric model set 32-bit CRC is used for data validation, implementation of the algorithm is complete, and use ALTERA company EDA tools simulation platform simulation.simulation results show that the design fully meet the fiber-optic communication data validation. using VHDL modeling and QuartuslI 9.1 as compiledthe high-speed, high-capacity
