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 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
IQ Instruction Queue. Part of the core architecture.
IVR
Integrated Voltage Regulation (IVR): The processor supports several integrated
voltage regulators.
Jitter
Any timing variation of a transition edge or edges from the defined Unit Interval
(UI).
LGA2011-v3 Socket
The 2011-v3 land FC-LGA package mates with the system board through this
surface mount, 2011-v3 contact socket.
LLC Last Level Cache
LRDIMM Load Reduced Dual In-line Memory Module
LRU Least Recently Used. A term used in conjunction with cache allocation policy.
MESIF
Modified/Exclusive/Shared/Invalid/Forwarded. States used in conjunction with
cache coherency
MLC Mid Level Cache
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 next generation chipset with centralized platform
capabilities including the main I/O interfaces along with display connectivity,
audio features, power management, manageability, security and storage
features.
PCI Express* 2.0 PCI Express Generation 2.0
PCI Express* 3.0
The third generation PCI Express specification that operates at twice the speed
of PCI Express 2.0 (8 Gb/s); PCI Express 3.0 is completely backward compatible
with PCI Express 1.0 and 2.0.
PECI Platform Environment Control Interface
Processor Includes the 64-bit cores, uncore, I/Os, and package
Processor Core
The term "processor core" refers to Si die itself which 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.
Rank
A unit of DRAM corresponding four to eight devices in parallel. These devices are
usually, but not always, mounted on a single side of a DDR4 DIMM.
RDIMM Registered Dual In-line Memory Module
RTID
Request Transaction IDs are credits issued by the Cbo to track outstanding
transaction, and the RTIDs allocated to a Cbo are topology dependent.
SCI System Control Interrupt. Used in ACPI protocol.
SKU
Stock Keeping Unit (SKU) is a subset of a processor type with specific features,
electrical, power and thermal specifications. Not all features are supported on all
SKUs. A SKU is based on specific use condition assumption.
SMBus
System Management Bus. A two-wire interface through which simple system
and power management related devices can communicate with the rest of the
system.
SSE Intel
®
Streaming SIMD Extensions (Intel
®
SSE)
STD Suspend-to-Disk
