摘要
CRC校验是一种数据通信中广泛应用的检错方法。在多种通信协议的帧结构中有一个16位或32位的FCS,就是利用CRC编码保证数据帧的无误传输。本文阐述了CRC算法的基本原理,并基于实际系统需要,在FPGA中实现了CRC算法。
CRC is widely used in checking mistakes in digital communication.In many kinds of communication protocol frame structure,there are 16bits or 32bits FCS which uses to guarantee the unmistakable data transmission.This article elaborates the basic principle of the CRC algorithm.Based on actual systematic need,and realizes the CRC algorithm in FPGA.
