CRC8校验算法及在飞机电气综合试验管理系统的应用

CRC8 Calibration Algorithm and Its Application in Management System for Rircraft Electric Comprehensive Test

为了满足飞机电气综合试验管理系统高速网络通信中数据校验的要求,通过分析串行算法的不足之后采用并行算法实现CRC8校验。为了推导出CRC8校验的并行算法,首先通过描述除法电路结构和运算步骤,推导出串行算法及其实现电路,然后进一步通过演算实现其并行算法。这里首次给出了应用并行算法基于LabVIEW实现CRC8校验的方法,并将其应用于飞机电气综合试验管理系统。

In order to meet the requirements of data validation in high-speed network communications of the plane electrical comprehensive test management system,the parallel algorithm is adopted to realize CRC8 calibration after disscussing the defect of serial algorithm.To derive the parallel algorithm for CRC8 calibration,the division circuit structure and operation procedures are described,and the serial algorithm and its realization circuit are derived.After that,the parallel algorithm is realized through further calculus.The CRC8 calibration was achieved by the parallel algorithm based on LabVIEW.It was applied successfully to plane electric comprehensive test management system.
