MXI-2 Configuration Reference Manual
A Servant-only device that supports VXIbus configuration registers.
Register-based devices are typically controlled by message-based devices
via device-dependent register reads and writes.
An acknowledge by a destination that signifies that the cycle did not
complete and should be repeated.
A message-based Commander located at Logical Address 0, which
provides configuration management services such as address map
configuration, Commander and Servant mappings, and self-test and
diagnostic management.
Seconds
A device controlled by a Commander; there are message-based and
register-based Servants.
A communication protocol that uses a block of memory accessible to both
a client and a server. The memory block operates as a message buffer for
communications.
Single In-line Memory Module
A functional part of a MXI/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 is in slave mode it if is responding to a bus cycle.
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 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.
Small Outline Dual Inline Memory Module; used in the PXI-8320.
A device whose logical address cannot be set through software; that is, it is
not dynamically configurable.
