摘　　要：基于CRC循环冗余校验和偶校验的基本原理,并根据TCN协议,在MVB总线中设计了一个由7位CRC校验码和1位偶校验位构成的具有双重校验的8位校验序列,大大提高了数据传输中的检错能力与可靠性。本设计采用QuartusⅡ软件与VHDL语言实现,最终得到校验序列编码器的正确仿真波形,结果表明完全达到了预期的设计要求。In this paper,based on the principle of CRC and even parity,and according to the TCN protocol,a 8-bit check sequence composed of a 7-bit CRC and a 1-bit even parity is designed in MVB,which greatly enhances its error detecting capability and reliability during the data transmission due to its duplication check.The check sequence encoding is described with VHDL language and Quartus II.
