Single In-line Memory Module
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.
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.
Sub Miniature Type B connector that features a snap coupling for fast
connection.
A device whose logical address cannot be set through software; that is, it is
not dynamically configurable.
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.
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.
Either TTL or ECL lines used for intermodule communication.
