IEEE 1. 39. 4 Wikipedia. IEEE 1. 39. 4 is an interface standard for a serial bus for high speed communications and isochronous real time data transfer. It was developed in the late 1.

The 1. 39. 4 interface is also known by the brands i. LINK Sony, and Lynx Texas Instruments. The copper cable it uses in its most common implementation can be up to 4. Power is also carried over this cable allowing devices with moderate power requirements to operate without a separate power supply. Fire. Wire is also available in wireless, Cat 5, fiber optic, and coaxial versions. The 1. 39. 4 interface is comparable to USB, though USB requires a master controller and has greater market share.

Working Group, largely driven by contributions from Apple, although major contributions were also made by engineers from Texas Instruments, Sony, Digital Equipment Corporation, IBM, and INMOSSGS Thomson now STMicroelectronics. IEEE 1. 39. 4 is a serial bus architecture for high speed data transfer. Fire. Wire is a serial bus, meaning that information is transferred one bit at a time. Parallel buses utilize a number of different physical connections, and as such are usually more costly and typically heavier. IEEE 1. Apple intended Fire. Wire to be a serial replacement for the parallel SCSI bus while providing connectivity for digital audio and video equipment. Apples development began in the late 1.

Apple released its last computers featuring Fire. Wire late 2. 01. 2. By 2. 01. 4 Thunderbolt had become a standard feature across Apples entire line of computers effectively becoming the spiritual successor to Fire. Wire in the Apple ecosystem. Sonys implementation of the system, i. LINK, used a smaller connector with only four signal conductors, omitting the two conductors that provide power for devices in favor of a separate power connector. This style was later added into the 1. This port is sometimes labeled S1. S4. 00 to indicate speed in Mbits. The system was commonly used to connect data storage devices and DV digital video cameras, but was also popular in industrial systems for machine vision and professional audio systems. Many users preferred it over the more common USB 2. Benchmarks show that the sustained data transfer rates are higher for Fire. Wire than for USB 2. USB 3. 0. Results are marked on Apple Mac OS X but more varied on Microsoft Windows. Implementation of IEEE 1.

Technical specificationseditFire. Wire can connect up to 6. Parallel SCSIs electrical bus topology. It allows peer to peer device communication  such as communication between a scanner and a printer  to take place without using system memory or the CPU. Fire. Wire also supports multiple hosts per bus. It is designed to support plug and play and hot swapping. The copper cable it uses in its most common implementation can be up to 4. SCSI cables. In its six conductor or nine conductor variations, it can supply up to 4. Fire. Wire devices implement the ISOIEC 1. ROM model for device configuration and identification, to provide plug and play capability. All Fire. Wire devices are identified by an IEEE EUI 6. Fire. Wire devices are organized at the bus in a tree topology. Each device has a unique self ID. One of the nodes is elected root node and always has the highest ID. The self IDs are assigned during the self ID process, which happens after each bus resets. The order in which the self IDs are assigned is equivalent to traversing the tree depth first, post order. Fire. Wire is capable of safely operating critical systems due to the way multiple devices interact with the bus and how the bus allocates bandwidth to the devices. Fire. Wire is capable of both asynchronous and isochronous transfer methods at once. Isochronous data transfers are transfers for devices that require continuous, guaranteed bandwidth. In an aircraft, for instance, Isochronous devices include control of the rudder, mouse operations and data from pressure sensors outside the aircraft. All these elements require constant, uninterrupted bandwidth. To support both elements, Fire. Wire dedicates a certain percentage to isochronous data and the rest to asynchronous data. In IEEE 1. 39. 4, 8. Encoding schemeeditFire. Wire uses Data strobe encoding DS encoding. In DS encoding, two non return to zero NRZ signals are used to transmit the data with high reliability. The NRZ signal sent is fed with the clock signal through an XOR gate, creating a strobe signal. This strobe is then put through another XOR gate along with the data signal to reconstruct the clock. This in turn acts as the buss Phase locked loop for synchronization purposes. ArbitrationeditThe process of the bus deciding which node gets to transmit data at what time is known as arbitration. Each arbitration round lasts about 1. During the round, the root node device nearest the processor sends a cycle start packet. All nodes requiring data transfer respond, with the closest node winning. After the node is finished, the remaining nodes take turns in order. This repeats until all the devices have used their portion of the 1.
