摘要
为确保数据安全,CRC广泛应用于工业通信中。高速动车与地面应答器之间的数据传输采用的是75位的CRC校验,对于这种复杂的CRC校验需要非常复杂的软件,也会消耗大量硬件资源。以75位CRC模块的设计为例,探讨大容量高复杂度的CRC校验模块的优化设计方法。
CRC is widely used to insure the safety of data in industry communication.For the safety reason,75 bits of CRC is used in data communication between Balise and EMU in Railways High-speed.The complex CRC module need more complex software and also consumes large hardware resources.This file will discuss optimization design method for the large capacity and high complexity CRC module,for example 75 bit CRC module which is used in EMU of Railways High speed.
