摘要
详细介绍了实际中经常用到的一些差错控制方法,提出了一种基于CDT远动规约的CRC计算原理及实现方法,并给出了CRC检错码在8051单片机中软件实现的源代码.与目前采用的查表法比较,不需要存放余数表的高速存储器,减少了时延,从而达到提高传输效率的效果.
In this papre, some mistake control methods which are often used in reality are introduced in detail. The principle and implementation of a CRC Code computing based on CDT protocol are described the source code for implementing CRC code in 8051 micro processor series is also present. Comparing with Table Lookup Algorithm, it need not the high speed RAM which was used to store the remainder table, and decrease the delay. So it can improve the efficiency of the transmission.
