programming, instructions are not case-sensitive. Y ou ma y use
either uppercase or lowercase.
Numbers Hexadecimal numbers are represented by a string of
hexadecimal digits followed by the character H. A zero prefix is
added to numbers that begin with A through F. (For example, FF
is shown as 0FFH.) Decimal and binary numbers are
represented by their customary notations. (That is, 255 is a
decimal number and 1111 1111 is a binary number. In some
cases, the letter B is added for clarity.)
Units of Measure The following abbreviations are used to represent units of
measure:
A amps, amperes
GByte gigabytes
KByte kilobytes
KΩkilo-ohms
mA milliamps, milliamperes
MByte megabytes

Signal Names Signal names are shown in uppercase. When several signals
share a common name, an individual signal is represented by
the signal name followed by a number, while the group is
represented by the signal name followed by a variable (n). For
example, the lower chip-select signals are named CS 0#, CS1#,
CS2#, and so on; they are collectively called CSn#. A pound
symbol (#) appended to a signal name identifies an active-low
signal. Port pins are represented by the port abbreviation, a
period, and the pin number (e.g., P1.0).

1.3Glossary of Terms and Acronyms
This section defines conventions and terminology used throughout this document.
AggressorA network that transmits a coupled signal to another network.
Anti-etchAny plane-split, void or cutout in a VCC or GND plane.
Assisted Gunning Transceiver Logic+
The front-side bus uses a bus technology called AGTL+, or
Assisted Gunning Transceiver Logic. AGTL+ buffers are opendrain, and require pull-up resistors to provide the high logic level
and termination. AGTL+ output buffers differ from GTL+ buffers
with the addition of an active pMOS pull-up transistor to assist
the pull-up resistors during the first clock of a low-to-high
voltage transition.
Asynchronous GTL+ The processor does not utilize CMOS voltage levels on any
signals that connect to the processor. As a result, legacy input
signals such as A20M#, IGNNE#, INIT#, LINT0/INTR, LINT1/
NMI, PWRGOOD, SMI#, SLP#, and STPCLK# utilize GTL+ input
buffers. Legacy output signals (FERR# and IERR#) and nonAGTL+ signals (THERMTRIP# and PROCHOT#) also utilize GTL+
output buffers. All of these signals follow the same DC
requirements as AGTL+ signals, however the outputs are not
actively driven high (during a logical 0 to 1 transition) by the
processor (the major difference between GTL+ and AGTL+).
These signals do not have setup or hold time specifications in
relation to BCLK[1:0], and are therefore referred to as
“Asynchronous GTL+ Signals”. However , all of the Asynchrono us
GTL+ signals are required to be asserted for at least two BCLKs
in order for the processor to recognize them.
Bus AgentA component or group of components that, when combined,
represent a single load on the AGTL+ bus.
CrosstalkThe reception on a victim network of a signal imposed by
Flight TimeFlight time is a term in the timing equation that includes the
aggressor network(s) through inductive and capacitive coupling
between the networks.
• Backward Crosstalk - Coupling that creates a signal in a
victim network that travels in the opposite direction as the
aggressor’s signal.
• Forward Crosstalk - Coupling that creates a signal in a
victim network that travels in the same direction as the
aggressor’s signal.
• Even Mode Crosstalk - Coupling from a signal or multiple
aggressors when all the aggressors switch in the same
direction that the victim is switching.
• Odd Mode Crosstalk - Coupling from a signal or multiple
aggressors when all the aggressors switch in the opposite
direction that the victim is switching.

Intel® CoreTM 2 Duo processor with the Mobile Intel® 945GME Express Chipset
Intel® 945GME Express Chipset—About This Manual
needed to ensure the setup time of the receiver . More precisely,
flight time is defined as:
• The time difference between a signal at the input pin of a
receiving agent crossing the switching voltage (adjusted to
meet the receiver manufacturer’s conditions required for
AC timing specifications; i.e., ringback, etc.) and the output
pin of the driving agent crossing the switching voltage
when the driver is driving a test load used to specify the
driver’s AC timings.
• Maximum and Minimum Flight Time - Flight time variations
are caused by many different parameters. The more
obvious causes include variation of the board dielectric
constant, changes in load condition, crosstalk, power noise,
variation in termination resistance, and differences in I/O
buffer performance as a function of temperature, voltage,
and manufacturing process. Some less obvious causes
include effects of Simultaneous Switching Output (SSO)
and packaging effects.
• Maximum flight time is the largest acceptable flight time a
network will experience under all conditions.
• Minimum flight time is the smallest acceptable flight time a
network will experience under all conditions.
Infrared Data Assoc. The Infrared Data Association (IrDA) has outlined a specification
for serial communication between two devices via a bidirectional infrared data port. The 945GME platform has such a
port and it is located on the rear of the platform between the two
USB connectors.
IMVP6The Intel Mobile Voltage Positioning specification for the Intel
®
Core™ 2 Duo Processor. It is a DC-DC converter module that
supplies the required voltage and current to a single processor.
Inter-Symbol Interference
Inter-symbol interference is the effect of a previous signal (or
transition) on the interconnect delay. For example, when a
signal is transmitted down a line and the reflections due to the
transition have not completely dissipated, the following data
transition launched onto the bus is affected. ISI is dependent
upon frequency, time delay of the line, and the reflection
coefficient at the driver and receiver . ISI may impact both timing
and signal integrity.
Media Expansion Card
The Media Expansion Card (MEC) provides digital display options
through the SDVO interface. The MEC card also incorporates
video-in.
NetworkThe network is the trace of a Printed Circuit Board (PCB) that
completes an electrical connection between two or more
components.
OvershootThe maximum voltage observed for a signal at the device pad,
measured with respect to VCC.
PadThe electrical contact point of a semiconductor die to the
package substrate. A pad is only observable in simulations.
PinThe contact point of a component package to the traces on a
substrate, such as the motherboard. Signal quality and timings
may be measured at the pin.

and the arrival of a valid clock edge. This window may be
different for each type of bus agent in the system.
Simultaneous Switching Output (SSO) effects are differences in
electrical timing parameters and degradation in signal quality
caused by multiple signal outputs simultaneously switching
voltage levels in the opposite direction from a single signal or in
the same direction. These are called odd mode and even mode
switching, respectively . This simultaneous switching of multiple
outputs creates higher current swings that may cause additional
propagation delay (“push-out”) or a decrease in propagation
delay (“pull-in”). These SSO effects may impact the setup and/
or hold times and are not always taken into account by
simulations. System timing budgets should include margin for
SSO effects.
