ASYNC
Asynchronous communication is transmission of data without the use of an external clock signal.
Bridge
The logic that connects one computer bus to another, allowing an agent on one bus to access an agent on the other.
BSP
Software Board Support Package, such as Linux or VxWorks.
ECC
Error Correction Codes is a method used to detect and correct errors introduced during storage or transmission of data.
EEPROM
Electrically Erasable Programmable Read-Only Memory.
Ethernet
Ethernet is a family of frame-based computer networking technologies for local area networks (LANs).
Flash
Flash memory is a non-volatile computer storage chip that can be electrically erased and reprogrammed.
GbE
Gigabit Ethernet.
GPIO
General Purpose Input / Output.
IEEE
Institute of Electrical and Electronics Engineers.
MiniPCIe
A small form factor option module with a single PCI Express link that mounts securely on a host card.
NOR Flash
A type of Flash memory that offers fast and random accesses.
NVRAM
Non-Volatile Random Access Memory.
OpenVPX
The OpenVPX (VITA 65) System Specification is the first system-level VPX specification dedicated to the interoperability of
multi-vendor system and subsystem building blocks.
OS
Software Operating System such as Linux or VxWorks.
PCI
Peripheral Component Interconnect is an industry0standard specification for connecting hardware devices to a computer’s central
processor.
PCIe or PCI
Express
Peripheral Component Interconnect Express. A high-speed serial computer expansion bus standard designed to replace the older
PCI, PCI-X, and AGP bus standards.
PCI-X
Peripheral Component Interconnect Extended is a performance-enhanced version of the PCI bus.
PMC
A PCI Mezzanine Card is a printed circuit board manufactured to the IEEE P1386.1 standard. This standard combines the electrical
characteristics of the PCI bus with the mechanical dimensions of the Common Mezzanine Card or CMC format (IEEE 1386 stan-
dard).
RS-232
RS-232 (Recommended Standard 232) is a standard for serial binary single-ended data and control signals connecting between a
DTE (Data Terminal Equipment) and a DCE (Data Circuit-terminating Equipment).
RS-422
RS-422 (Recommended Standard 422) provides for data transmission using balanced or differential signaling with unidirectional/
non-reversible, terminated, or non-terminated transmission lines, point to point, or multi-drop.
SBC
Single Board Computer.
VITA
VMEBUS International Trade Association. VITA is an incorporated, non-profit organization of vendors and users having a common
market interest in real-time, modular embedded computing systems.
VPX
VPX, formerly known as VITA 46, is an ANSI standard (ANSI/VITA 46.0-2007) [1] that provides VMEbus-based systems with support
for switched fabrics over a high speed connector.
XMC
XMC is a PMC with high-speed serial fabric interconnect defined by the VITA 42 standard. XMC specifies an additional connector
(P5) that support PCI Express(VITA 42.3) or other high speed serial formats such as Serial RapidIO (VITA 42.2) and Parallel Rapi-
dIO (VITA 42.1).
