基于C8051F的CRC校验算法的实现

Implementation of the CRC Algorithm Based on C8051F

介绍了CRC(循环冗余码校验)原理及集成混合信号片上系统单片机C8051F的新特性,推导获得以字节为单位的数据序列CRC码递推算法,利用C8051F单片机的自带CAN2.0B总线接口控制器可以很方便的组成基于网络通信的智能仪器测控系统,给出了应用C8051F的CAN2.0B总线接口通信时的CRC码运算实例,此算法完全可以满足工业测控系统实时性的需要。

The principle of CRC （cyclic redundancy checking） and the new characteristics of SOC{system on chip） C8051F arc introduced. The recursive algorithm on the arrays of data CRC with Byte as the unit is derived. By using integrated CAN2.0B bus interface controller of MCU C8051 F, it is easy to compose the intelligent instrument measuring and controlling system based on network communication. The CRC example is given when the CAN2.0B bus interlace of C8051F on communication is applied. The algorithm completely meets the real time demand of the industrial measuring and controling systems.
