In the paper, we give the method of checking form based on module 2 by searching the 16 bits Cyclic Redundancy Check Code(CRCC) ( CRC-CCITT ). Experiments show that the reliability in system communication is guaranteed and the computational speed is greatly improved. 本文研究了16位的循环冗余校验码(CRCC)CRC-CCITT在数据通信中的应用,给出了基于模2运算的查表法,实验证明:在保证了系统通信可靠性的基础上,大大提高了计算速度。
This paper expounded on the coding of Cyclic Redundancy Check code ( CRC ) and the error-checked method and gave forth highly effective CRC code and the source code of error-checked function coding by C language, which can act in communication software directly. 阐述了循环冗余校验码(CRCC)(CRC)的编码和错误检测方法,给出了可在通信软件中直接作用的高效的C语言CRC编码和检错函数源代码。
