Shared Memory A communication protocol that uses a block of memory that is
Protocol accessible to both a client and a server. The memory block operates as
a message buffer for communications.
SIMM Single In-line Memory Module
slave 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.
slave-mode operation A device is in slave mode it if is responding to a bus cycle.
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
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.
statically configured A device whose lo gical a ddre ss canno t be set thr oug h software ;
device that is, it is not dynamically configurable.
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
