Enumeration
An initialization process after reset that automatically assigns each StarFab-
ric-enabled node in the switch fabric with a unique identifier and provides
information about the switch fabric’s topology.
Isochronous
Refers to a data communications system where data must be delivered
within a certain amount of time. For example, multimedia streams require an
isochronous transport mechanism to ensure that data is delivered as fast as it
is displayed to ensure the audio is synchronized with the video.
Leaf
Refers to any edge node that is not configured as a Root bridge in a StarFab-
ric. Typically, Leaf refers to downstream StarFabric-enabled edge nodes. The
Leaf node requires reset and enumeration from the Root node to join the Star-
Fabric switch fabric.
LVDS
Low Voltage Differential Signaling (IEEE 1596.3) is a low noise, low power,
low amplitude method for high-speed (gigabits per second) data transmission
over copper wire. Low voltage means the standard 5 volts used for normal
digital I/O is replaced by either 3.3 volts or 1.5 volts.
Standard I/0 signaling,
data storage depends on actual voltage level to maintain a signal. Voltage
level is affected by wire length, meaning longer wires increase resistance and
minimize voltage. With LVDS, data storage is distinguished only by positive
and negative voltage values, not the voltage level, so data travels over greater
lengths of wire, maintaining a clear and consistent data stream.
PCI-SB StarFabric PCI Interface Card
Refers to the PCI-SB StarFabric PCI Interface card that provides a PCI-to-
StarFabric bridge interface to connect legacy PCI devices to a StarFabnc
switch fabric. It installs in any standard PCI slot on a PCI 2.2 compliant
motherboard.
