Glossary
MB megabytes of memory
MBLT eight-byte block transfers in which both the Address bus and the Data bus
are used to transfer data
Mbytes/s a unit for data transfer that means 1 million or 10
6
bytes/s
memory buffer See buffer.
MFLOPS million floating-point operations per second—the unit for expressing the
computational power of a processor
MIO multifunction I/O
MIPS million instructions per second—the unit for expressing the speed of
processor machine code instructions
MITE MXI Interfaces to Everything is a custom ASIC designed by National
Instruments that implements the PCI bus interface. The MITE supports bus
mastering for high speed data transfers over the PCI bus.
MS million samples
MSB most significant bit
MTBF mean time between failure
multiplexed mode an SCXI operating mode in which analog input channels are multiplexed
into one module output so that your cabled DAQ device has access to the
module’s multiplexed output as well as the outputs on all other multiplexed
modules in the chassis through the SCXI bus. Also called serial mode.
mux multiplexer—a switching device with multiple inputs that sequentially
connects each of its inputs to its output, typically at high speeds, in order to
measure several signals with a single analog input channel
N
NB NuBus—a slot-dependent, 32-bit bus type used in Macintosh computers
that has 32 interrupts
NC normally closed, or not connected
NI-DAQ National Instruments driver software for DAQ hardware
