S
s Seconds.
SIMM Single In-line Memory Module.
slave A functional part of a VME/VXIbus device that detects data transfer cycles
initiated by a VMEbus master and responds to the transfers when the
address specifies one of the device’s registers.
Slot 0 device A device configured for installation in Slot 0 of a VXIbus mainframe. This
device is unique in the VXIbus system in that it performs the VXI/VMEbus
System Controller functions, including clock sourcing and arbitration for
data transfers across the backplane. Installing such a device into any other
slot can damage the device, the VXIbus backplane, or both.
SMB Sub Miniature Type B connector that features a snap coupling for fast
connection.
statically configured
device
A device whose logical address cannot be set through software; that is, it is
not dynamically configurable.
streaming data Data that is structured and processed in a continuous flow, such as digital
audio and video. In IEEE 1394, this is often sent with the isochronous
protocol rather than the standard asynchronous protocol.
SYSFAIL A VMEbus signal that is used by a device to indicate an internal failure.
A failed device asserts this line. In VXI, a device that fails also clears its
PASSed bit in its Status register.
T
trigger Either TTL or ECL lines used for intermodule communication.
TTL Transistor-Transistor Logic
V
V Volts.
VGA Video Graphics Array; the minimum video display standard for all PCs.
