The IEEE 1394 bus asynchronous transmission time delay property is studied. The calculation method of each IEEE 1394 asynchronous transmission process is provided. The experiment measured the asynchronous transmission time delay between two IEEE 1394 nodes. A comparison between the calculation results and the experiment results is undertaken. The work of this paper helps relevant researchers to get a clear view of the makeup, property and influence factors of the IEEE 1394 bus asynchronous transmission time delay, and provided a reference for the application of IEEE 1394 bus in real time systems.
