Technology
Technology that provides power management capabilities.
Execute Disable Bit
The Execute Disable bit allows memory to be marked as executable or non-
executable, when combined with a supporting operating system. If code attempts
to run in non-executable memory, the processor raises an error to the operating
system. This feature can prevent some classes of viruses or worms that exploit
buffer overrun vulnerabilities and can, thus, help improve the overall security of the
system. See the Intel

64 and IA-32 Architectures Software Developer's Manuals
for more detailed information.
EU Execution Unit
FCLGA Flip Chip Land Grid Array
(G)MCH
Legacy component – Graphics Memory Controller Hub. Platforms using LGA 1156
processors do not use a (G)MCH component.
ICH
The legacy I/O Controller Hub component that contains the main PCI interface, LPC
interface, USB2, Serial ATA, and other I/O functions. It communicates with the
legacy (G)MCH over a proprietary interconnect called DMI. Platforms using LGA
1156 processors do not use an ICH component.

HT Technology)
that allows an execution core to function as two logical processors.
Intel

Turbo Boost
Technology
Intel
®
Turbo Boost Technology is a feature that allows the processor core to
opportunistically and automatically run faster than its rated operating frequency if it
is operating below power, temperature, and current limits.

Trusted Execution Technology
Intel

VT-d
Intel
®
Virtualization Technology (Intel
®
VT) for Directed I/O. Intel VT-d is a
hardware assist, under system software (Virtual Machine Manager or OS) control,
for enabling I/O device virtualization. VT-d also brings robust security by providing
protection from errant DMAs by using DMA remapping, a key feature of Intel VT-d.
Intel
®
Virtualization
Technology
Processor virtualization which when used in conjunction with Virtual Machine
Monitor software enables multiple, robust independent software environments
inside a single platform.
ITPM Integrated Trusted Platform Module
IOV I/O Virtualization
LCD Liquid Crystal Display
LVDS
Low Voltage Differential Signaling. A high speed, low power data transmission
standard used for display connections to LCD panels.
MCP Multi-Chip Package
NCTF
Non-Critical to Function: NCTF locations are typically redundant ground or non-
critical reserved, so the loss of the solder joint continuity at end of life conditions
will not affect the overall product functionality.
PCH
Platform Controller Hub. The new, 2009 chipset with centralized platform
capabilities including the main I/O interfaces along with display connectivity, audio
features, power management, manageability, security and storage features.
PECI Platform Environment Control Interface
PEG
PCI Express* Graphics. External Graphics using PCI Express Architecture. A high-
speed serial interface whose configuration is software compatible with the existing
PCI specifications.
