How Does FireWire Work?

The IEEE-1394 High Performance Serial Bus is a remarkable engineering feat that has occupied many highly-creative digital circuit designers and software programmers for the past 10 years. FireWire is a very complex serial bus protocol, as evidenced by the hundreds of pages that comprise its standard specification. The following list, with links to pages providing more detailed information, is a very simplified description of the external and internal workings of the FireWire bus:
