摘　　要：简要介绍了IEEE1394 a异步数据包,对IEEE1394 a包长配置与总线传输性能的影响进行了研究,推导出异步传输模式在考虑到误码率影响的条件下,实际传输数据量与包长配置之间的关系,并对该数学模型进行了初步验证,最终模型结果和试验结果吻合较好,表明利用该数学模型分析IEEE1394包长配置、误码率与实际传输数据量之间的关系快捷有效,可以应用于工程分析。得出在误码率较小的情况下,异步数据包包长设置得越大,其IEEE1394总线的传输性能越好的结论。This paper briefly introduces the asynchronous packet of IEEE 1394a. The influence of IEEE 1394a packet configuration on the bus performance is analyzed. Then in asynchronous transfer mode of considering bit error rate, the relationship between data transmitted and packet length is derived. In addition, the mathematical model is preliminarily verified. The agreement of the model results with the experimental data indicates this mathematical model could be used to analyze the relation of data transmitted, packet length and bit error rate quickly and effectively in engineering analyses. It is found that with low bit error rate large packet configuration can improve IEEE 1394 bus asynchronous transmitting performance.
