1.1
Terminology
Term
Definition
#
A “#” symbol after a signal name refers to an active low signal, indicating a
signal is in the active state when driven to a low level. For example, when
RESET# is low, a reset has been requested. Conversely, when NMI is high,
a nonmaskable interrupt has occurred. In the case of signals where the
name does not imply an active state but describes part of a binary
sequence (such as
address
or
data
), the “#” symbol implies that the signal
is inverted. For example, D[3:0] = “HLHL” refers to a hex “A”, and D[3:0]#
= “LHLH” also refers to a hex “A” (H= High logic level, L= Low logic level).
Front Side Bus
(FSB)
Refers to the interface between the processor and system core logic (also
known as the chipset components).
AGTL+
Advanced Gunning Transceiver Logic. Used to refer to Assisted GTL+
signaling technology on some Intel processors.
Storage
Conditions
Refers to 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” (i.e., 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.
Processor Core
Processor core die with integrated L1 and L2 cache. All AC timing and signal
integrity specifications are at the pads of the processor core.
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.
Intel® 64
Technology
64-bit memory extensions to the IA-32 architecture.
Half ratio support
(N/2) for Core to
Bus ratio
Intel Core 2 Duo processors and Intel Core 2 Extreme processors support
the N/2 feature that allows having fractional core-to-bus ratios. This feature
provides the flexibility of having more frequency options and being able to
have products with smaller frequency steps.
TDP
Thermal Design Power.
V
CC
The processor core power supply.

SS
