Introduction
Firewire:
Oficially known as IEEE-1394
next generation of Plug and Play
With standard speeds of 100, 200 and 400 Mbps
ideal for connecting high-end consumer electronics (such as digital A/V equipment )

Research Motivation in Firewire
The ability to work with time sensitive data is growing in importance
Small products are favored for portability, convenience, and material usage resources
The need and desire for Peer to Peer computing is growing
There is a desire to keep data digital for as long as possible as a means to reduce system cost, complexity, and improve signal integrity
In multimedia market, most of the data is video and audio
Evolution of IEEE
Apple started full scale development in 1988
Xilinx-based 12.288 Mb aud/sec system
49.152 Mbaud cable transceiver fabbed
Apple designed 98.302 MBit/sec PHY in 1992
TI built first test chips
Connector based on Nintendo Gameboy
TI delivered “draft 6” PHY. It was working
Apple and TI win “Most Significant Technology” award
IEEE 1394-1995 was ratified in 1995
First products
Sony DV camcorders in 1995, many others by 1997
Sony machine vision cameras
Bus Management Layer
Supports bus configuration and management activities
Depends on the capabilities of the node but all most support automatic bus configuration
Channel number and bus bandwidth allocation for asynchronous transfers
The 1394 specification identifies three global management roles:
Cycle master
Isochronous Resource Manager
Bus manager
