Mmaster A functional part of a VME/VXIbus device that initiates data
transfers on the backplane. A transfer can be either a read or a
write.
MB megabytes of memory
message-based device An intelligent device that implements the defined VXIbus
registers and communication protocols. These devices are able to
use Word Serial Protocol to communicate with one another
through communication registers.
MITE A National Instruments custom ASIC, a sophisticated dual-
channel DMA controller that incorporates the Synchronous MXI
and VME64 protocols to achieve high-performance block
transfer rates.
MTBF Mean Time Between Failure
NNI-VXI The National Instruments bus interface software for
VME/VXIbus systems.
Non-Slot 0 device A device configured for installation in any slot in a VXIbus
mainframe other than Slot 0. Installing such a device into Slot 0
can damage the device, the VXIbus backplane, or both.
PPCI Peripheral Component Interconnect. The PCI bus is a high-
performance 32-bit or 64-bit bus with multiplexed address and
data lines.
Rregister-based device 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.
