Abstract: Based on the principles and the characteristics of Cyclic Redundancy Check,the problems with CRC-16’s programme algorithm and programme realization have been analysed,and its reliability and validity have been testified by using LabVIEW technology.It shows that the problems of the software and hardware realization of high-order CRC based on LabVIEW technology,in figure and programme language can be coped with well and intuitively.

Key words: Cyclic Redundancy Check； CRC-16； LabVIEW technology；
