摘要
在数字通信中,循环冗余校验(CyclicRedundancyCheck,CRC)是一种常用的差错控制方法,本文在讨论传统CRC算法的基础上,给出了一种适用于通用成帧协议(GenericFramingProcedure,GFP)的快速CRC算法,并给出了其硬件实现的VHDL(VeryhighspeedintegratedcircuitHaddwareDescriptionLanguade)源程序。硬件测试表明,其在实现效率、消耗资源等方面取得了较好效果。
In digital communications, CRC(Cyclic Redundancy Check) is a commonly used error control technology. This paper discusses the traditional CRC algorithms, and then presents a new CRC algorithm in GFP(Genetic Framing Procedure) to improve efficiency and reduce cost. In addition, the source code in VHDL is given for hardware realization.
