GFK-2896
For public disclosure
ACPI Open standard for O/S device configuration and power management
ATA A standard for connecting hard disk drives to an AT (Advanced Technology) bus
Mini Module mCOM10-L1500 form factor
BIOS Firmware resident in an Intel Architecture computer responsible for testing and
initializing system components, controlling the basic I/O (keyboard, display, disk drives,
COM ports, and such), and loading the operating system software
Carrier Board An application-specific circuit board that accepts a mCOM10-L1500
DP VESA-defined digital video interface to transport audio and video in a transmission
protocol
DVI A Digital Display Working Group (DDWG) standard that defines a standard video
interface supporting both digital and analog video signals. The digital signals use TMDS.
EFI Bootloader and runtime interface between platform firmware and an operating
system. Replacement for BIOS.
I 2 C Serial inter-chip bus. 2 wire (clock and data) signaling scheme allowing
communication between integrated circuits, primarily used to read and load register
values.
Inverted A logic value of 1 is represented by a low electrical signal
JTAG Typically used to refer to JTAG boundary scan
LPC Bus A low speed interface used for peripheral circuits such as Super I/O
controllers, which typically combine legacy-device support into a single IC
LVDS Widely used as a physical interface for TFT flat panels. LVDS can be used for
many high-speed signaling applications. In this document, it refers only to TFT flat-panel
applications.
MAC Communications protocol layer that controls access to the physical transmission
medium on a LAN. Also used to denote a MAC layer device.
Non-Inverted A logic value of 1 is represented by a high electrical signal.
PCI Local Bus Multi-plexed address/data plus control bus that can be 32 or 64–bits
wide and operate at 33 MHz or 66 MHz.
PCIe High-speed serialized follow-on to the PCI Local Bus. Next-generation
high-speed serialized I/O bus.
PHY Communications protocol layer that provides the transmission of bits over the
network medium. Also used to denote a PHY layer interface device.
Pin A signal contact used in the module
ROM Often the device referred to as a ROM can actually be written to, in a special
mode. Such writable ROMs are sometimes called Flash ROMs. BIOS is stored in ROM
or Flash ROM.
