Xmodem协议中CRC算法的FPAG实现

摘要

To solve the CRC in Xmodem protocol.This paper studies the CRC byte parallel computing principles based on the classic LFSR hardware circuits and the multi-byte CRC algorithm implementation.In the Quartus II environment,we can get the CRC of the Xmodem protocol and the multi-byte cycle parallel CRC algorithm to meet the high-speed real-time requirements through the simulation of the VHDL language.%基于解决Xmodem协议中CRC校验的目的,以经典的LFSR硬件电路为基础,采用了按字节并行运算CRC校验码,以及多字节CRC算法的方法。在Quartus II环境下,通过以VHDL语言仿真试验,得出Xmodem协议中CRC校验,以多字节循环并行CRC算法能够满足高速实时性要求的结论。
