 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 operating system) control, 

for enabling I/O device virtualization. Intel VT-d also brings robust security by 

providing protection from errant DMAs by using DMA remapping, a key feature of Intel 

VT-d.

IOV

I/O Virtualization

ISA

Industry Standard Architecture. This is a legacy computer bus standard for IBM PC 

compatible computers. 

ITPM

Integrated Trusted Platform Module

LCD

Liquid Crystal Display

LFM

Low Frequency Mode

LPC

Low Pin Count

LPM

Low Power Mode

LVDS

Low Voltage Differential Signaling. A high speed, low power data transmission 

standard used for display connections to LCD panels.

MLE

Measured Launched Environment 

MSI

Message Signaled Interrupt

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.

ODT

On-Die Termination

PAIR

Power Aware Interrupt Routing

PCH

Platform Controller Hub. The 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.

PGA

Pin Grid Array

PLL

Phase Lock Loop

PME

Power Management Event

PPD

Precharged Power Down

Processor

The 64-bit, single-core or multi-core component (package).

Processor Core

The term “processor core” refers to Si die itself that can contain multiple execution 

cores. Each execution core has an instruction cache, data cache, and 256-KB L2 cache. 

All execution cores share the L3 cache.

Processor Graphics

Intel Processor Graphics

Rank

A unit of DRAM corresponding four to eight devices in parallel, ignoring ECC. These 

devices are usually, but not always, mounted on a single side of a SO-DIMM.

SCI

System Control Interrupt. Used in ACPI protocol.

Intel SDRRS 

Technology

Intel Seamless Display Refresh Rate Switching Technology

SMEP

 Supervisor Mode Execution Protection
