摘要
文章对CRC校验算法的原理进行了深入分析,讨论了诸如移位寄存器初始值设置等在实际应用中算法遇到的问题,并给出了编码校验的范例程序。论文对MPEG-2系统层编码所用的CRC-32编码器模型进行了解释,并基于此模型设计了适合于采用软件实现的算法程序。
This paper analyzes the CRC algorithm in detail,and also discusses some problem that will occur in practi-cal cases,e.g.the setting of the initial value of the shift register.As a result,an example to resolve the problem is pro-vided.The paper also interprets the CRC-32decoder model used in the MPEG-2system standard,and proposes an al-gorithm suitable for software developing using the basic theory of the decoder model.
