cache
Small portion of high-speed memory used for temporary storage of
frequently used data.
CMOS
Complementary Metal Oxide Semiconductor—A type of integrated circuit.
CompactPCI
An adaptation of the PCI specification for industrial and/or embedded
applications that require a more robust mechanical form factor than desktop
PCI. CompactPCI provides a standard form factor for those applications
requiring the high performance of PCI as well as the small size and
ruggedness of a rack-mount system.
Controller
An embedded computer module which configures and accesses a series of
devices connected to a chassis backplane.

DIMM
Dual In-line Memory Module.
DMA
Direct Memory Access—A method by which data is transferred between
devices and internal memory without intervention of the central processing
unit.
