摘　　要：给出了ＣＲＣ码的查表生成算法和一个码表实例．所给算法适合用软件方法快速生成ＣＲＣ码．由于计算上的复杂性，ＣＲＣ码通常用硬件来产生，限制了在一些地方的应用．在应用系统中，用ＣＲＣ码取代简单的奇偶校验码能提高数据传输的可靠性．The table lookup algorithm and a table of CRC code were presented.Because of the complexity in calculation,CRC(cyclic redundancy check) code was usually generated by hardware,and its applications in some situation were limited.It can increase the reliability of data transmission to replace the simple parity check code with CRC code in application system.The algorithm gives a convenient approach to use CRC code in application system.

关 键 词：循环码 冗余编码 错误校验 算法
