Introduction
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.
Processor The 64-bit, single-core or multi-core component (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.
Processor Graphics Intel
®
Processor Graphics
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 SO-DIMM.
SCI System Control Interrupt. Used in ACPI protocol.
Storage Conditions
A non-operational state. The processor may be installed in a platform, in a tray,
or loose. Processors may be sealed in packaging or exposed to free air. Under
these conditions, processor landings should not be connected to any supply
voltages, have any I/Os biased or receive any clocks. Upon exposure to “free air”
(that is, unsealed packaging or a device removed from packaging material) the
processor must be handled in accordance with moisture sensitivity labeling
(MSL) as indicated on the packaging material.
TAC Thermal Averaging Constant.
TAP Test Access Point
TDP Thermal Design Power.
V
AXG
Graphics core power supply.
V
CC
Processor core power supply.
V
CCIO
High Frequency I/O logic power supply
V
CCPLL
PLL power supply

CCSA
System Agent (memory controller, DMI, PCIe controllers, and display engine)
power supply
V
DDQ
DDR3 power supply.
VLD Variable Length Decoding.
V
SS
Processor ground.
x1 Refers to a Link or Port with one Physical Lane.
x16 Refers to a Link or Port with sixteen Physical Lanes.
x4 Refers to a Link or Port with four Physical Lanes.
x8 Refers to a Link or Port with eight Physical Lanes.
