Overview

DTS Digital Thermal Sensor

ECC Error Correction Code

Enhanced Intel

SpeedStep

Technology

Allows the operating system to reduce power consumption when performance is

not needed.

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.

FIVR Fully Integrated the Voltage Regulator. Internal DC-to-DC voltage regulators

integrated into processor to provide various voltage levels.

Flit Flow Control Unit. The Intel

QPI Link layer’s unit of transfer; 1 Flit = 80-bits.

Functional Operation Refers to the normal operating conditions in which all processor specifications,

including DC, AC, system bus, signal quality, mechanical, and thermal, are

satisfied.

IMC

Integrated Memory Controller. System memory controller that is integrated in

the processor die.

IIO The Integrated I/O Controller. An I/O controller that is integrated in the

processor die.

QuickData

Technology

Intel

QuickData Technology is a platform solution designed to maximize the

throughput of server data traffic across a broader range of configurations and

server environments to achieve faster, scalable, and more reliable I/O.

Intel

QuickPath

Interconnect (Intel

QPI)

A cache-coherent, link-based Interconnect specification for Intel processors,

chipsets, and I/O bridge components.

Intel

64 Technology 64-bit memory extensions to the IA-32 architecture. Further details on Intel

Intel

Turbo Boost

Technology

Intel

Turbo Boost Technology is a way to automatically run the processor core

faster than the marked frequency if the part is operating under power,

temperature, and current specifications limits of the Thermal Design Power

(TDP). This results in increased performance of both single and multi-threaded

applications.

Trusted Execution Technology

Intel

Virtualization

Technology (Intel

VT)

Processor virtualization which when used in conjunction with Virtual Machine

Monitor software enables multiple, robust independent software environments

inside a single platform.

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. Intel

VT-d also brings robust

security by providing protection from errant DMAs by using DMA remapping, a

key feature of Intel

VT-d.

Integrated Heat Spreader

(IHS)

A component of the processor package used to enhance the thermal

performance of the package. Component thermal solutions interface with the

processor at the IHS surface.

Jitter Any timing variation of a transition edge or edges from the defined Unit Interval

(UI).

IOV I/O Virtualization

LGA1356 Socket The 1356-land FCLGA package mates with the system board through this surface

mount, 1356-contact socket.

LLC Last Level Cache

LRDIMM Load Reduced Dual In-line Memory Module

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.
