Introduction to IEEE1394 FireWire
FireWire is one of the fastest peripheral standards ever developed, transferring
data at up to 400Mbps with a road-map for even faster data rates in the near future.
With its high data-transfer speed and hot swappable, plug-and-play capability,
FireWire is the interface of choice for today’s digital audio and video devices and is an
excellent medium for interfacing cameras, sensors, embedded DSP resources, and PCs.
A Multitude of Benefits
- Up to 63 devices can be supported within the same Firewire network
- Transmissions between different devices on the Firewire network can occur speeds of 100Mbit/sec, 200Mbit/sec, or 400Mbit/sec
- Isochronous and Asynchronous communications Models are supported. Isochronous communications guarantees time based delivery of data packets for real-time critical applications. Asynchronous communications supports non real-time event messaging.
- Asynchronous and isochronous transactions can occur across the same Firewire interface, allowing both non-real-time and real-time critical applications on the same bus.
- Peer-to-peer transfers are supported without the need for a host (PC) device.
- Firewire cables carry both signals and power, reducing the need for separate power cables when devices are connected to a Firewire network.
- Devices can be connected and disconnected while the network is active.

Software Solutions
A number of software options are available for use with micro-line DSP systems:
- IEEE1394 FireWire API provides a portable a library of C-callable functions that support initialization, setup and transfer of isochronous and asynchronous data across FireWire for embedded micro-line DSP systems. It is a stepping stone for higher-level API's that provide additional capabilities:
Some developers may also wish to enable communications between their FireWire-based micro-line DSP system and a host PC. The FireAPI SDK from Unibrain provides developers with all the tools they need for developing and debugging any 1394 application in a Windows PC environment. Like the IEEE1394 FireWire API, the FireAPI™ SDK elimates the need for a lower-level understanding of the protocol and allows the developer to focus on applying its concepts.
