Introduction
1 Introduction
1.1 Overview
The Dual-Core Intel Itanium processor 9000 and 9100 series employs Explicitly Parallel
Instruction Computing (EPIC) design concepts for a tighter coupling between hardware
and software. In this design style, the interface between hardware and software is
engineered to enable the software to exploit all available compile-time information and
efficiently deliver this information to the hardware. It addresses several fundamental
performance bottlenecks in modern computers, such as memory latency, memory
address disambiguation, and control flow dependencies. The EPIC constructs provide
powerful architectural semantics and enable the software to make global optimizations
across a large scheduling scope, thereby exposing available Instruction Level
Parallelism (ILP) to the hardware. The hardware takes advantage of this enhanced ILP,
and provides abundant execution resources. Additionally, it focuses on dynamic runtime optimizations to enable the compiled code schedule to flow at high throughput.
This strategy increases the synergy between hardware and software, and leads to
greater overall performance.
The Dual-Core Intel Itanium processor 9000 and 9100 series provides a 6-wide and 8stage deep pipeline, running at up to 1.6 GHz. This provides a combination of abundant
resources to exploit ILP as well as increased frequency for minimizing the latency of
each instruction. The resources consist of six integer units, six multimedia units, two
load and two store units, three branch units, two extended-precision floating-point
units, and one additional single-precision floating-point unit per core. The hardware
employs dynamic prefetch, branch prediction, a register scoreboard, and non-blocking
caches to optimize for compile-time non-determinism. Three levels of on-die cache
minimize overall memory latency. This includes up to a 24 MB L3 cache, accessed at
core speed, providing up to 8.53 GB/sec. of data bandwidth. The system bus is
designed to support up to four physical processors (on a single system bus), and can
be used as an effective building block for very large systems. The balanced core and
memory subsystem provide high performance for a wide range of applications ranging
from commercial workloads to high-performance technical computing.
The Dual-Core Intel Itanium processor 9000 and 9100 series supports a range of
computing needs and configurations from a two-way to large SMP servers. This
document provides the electrical, mechanical and thermal specifications for the DualCore Intel Itanium processor 9000 and 9100 series for use while employing systems
with the processors.
1.2 Processor Abstraction Layer
The Dual-Core Intel Itanium processor 9000 and 9100 series requires implementationspecific Processor Abstraction Layer (PAL) firmware. PAL firmware supports processor
initialization, error recovery, and other functionality. It provides a consistent interface
to system firmware and operating systems across processor hardware
implementations. The Intel® Itanium® Architecture Software Developer’s Manual,
Volume 2: System Architecture, describes PAL. Platforms must provide access to the
firmware address space and PAL at reset to allow the processors to initialize.

Introduction
The System Abstraction Layer (SAL) firmware contains platform-specific firmware to
initialize the platform, boot to an operating system, and provide runtime functionality.
Further information about SAL is available in the Intel®Itanium®Processor Family
System Abstraction Layer Specification.
1.3 Mixing Processors of Different Frequencies and
Cache Sizes
All Dual-Core Intel Itanium processor 9000 and 9100 series on the same system bus
are required to have the same cache size (24 MB, 18 MB, 12 MB, 8 MB or 6 MB) and
identical core frequency. Mixing components of different core frequencies and cache
sizes is not supported and has not been validated by Intel. Operating system support
for multiprocessing with mixed components should also be considered.
While Intel has done nothing to specifically prevent processors within a multiprocessor
environment from operating at differing frequencies and differing cache sizes, there
may be uncharacterized errata that exist in such configurations. Customers would be
fully responsible for validation of system configurations with mixed components other
than the supported configurations described above.
1.4 Terminology
In this document, “the processor” refers to the “Dual-Core Intel Itanium processor
9000 and 9100 series” processor, unless otherwise indicated.
A ‘#’ symbol after a signal name refers to an active low signal. This means that a signal
is in the active state (based on the name of the signal) when driven to a low level. For
example, when RESET# is low, a processor reset has been requested. When NMI is
high, a non-maskable interrupt has occurred. In the case of lines 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).
The term “system bus” refers to the interface between the processor, system core logic,
and other bus agents. The system bus is a multiprocessing interface to processors,
memory, and I/O.
A signal name has all capitalized letters, for example, VCTERM.
A symbol referring to a voltage level, current level, or a time value carries a plain
subscript, for example, V
1.5 State of Data

that Intel is able to provide at the publication date of this document.

2.1 Dual-Core Intel® Itanium® Processor 9000 and

Most Dual-Core Intel Itanium processor 9000 and 9100 series signals use the Itanium
processor’s assisted gunning transceiver logic (AGTL+) signaling technology. The

2.1.1 System Bus Power Pins
VCTERM (1.2 V) input pins on the processor provide power to the driver buffers and ondie termination. The GND pins, in addition to the GND input at the power tab connector,
provide ground to the processor. Power for the processor core is supplied through the
power tab connector by V
to provide power to the system management bus (SMBus). The V
pins must remain electrically separated from each other.

Similarly, “AGTL+ Output Signals” refers to the AGTL+ output group as well as the

The Test Access Port (TAP) connection input signals use a non-differential receiver with
levels that are similar to AGTL+. No reference voltage is required for these signals. The
TAP Connection Output signals are AGTL+ output signals.
The processor system bus requires termination on both ends of the bus. The processor
system bus supports both on-die and off-die termination controlled by two pins, TERMA
and TERMB. Please see the TERMA and TERMB pin description in Section 2.2.2.
The HSTL clock signals are the differential clock inputs for the processor. The SMBus
signals and LVTTL power pod signals are driven using the 3.3 V CMOS logic levels listed
in Table 2-8 and Table 2-9, respectively.

pins must be pulled to GND in order to use off-die termination.
connected to VCTERM via resistor for the majority of platforms
supporting the Dual-Core Intel Itanium processor 9000 and
9100 series. The TUNER2 resistor is used to control the
termination resistance for the system bus I/O buffers. A lower
resistance will cause a lower on-die termination resistance. Ondie termination mode will only be selected if the TERMA and
TERMB pins are terminated as indicated above. The TUNER3 pin
will not be required for the majority of platforms supporting the
Dual-Core Intel Itanium processor 9000 and 9100 series. The
TUNER3 pin is used only in the case where A[21:17]# are driven
to all zeros or all ones during the configuration cycles at reset.
When all zeros or all ones are observed by the processor the
presence of the TUNER3 and TUNER1 pins is used to determine
system bus frequency. See Table 2-22 for the various TUNER pin
combinations and resulting system bus frequency and slew rate
combination.
No connections that constitute a current load can be made to
these pins.

2.4.1 Maximum Ratings
Table 2-12 contains the processor stress ratings. Functional operation at the absolute
maximum and minimum is neither implied nor guaranteed. The processor should not
receive a clock while subjected to these conditions. Functional operating conditions are
given in the DC tables. Extended exposure to the maximum ratings may affect device
reliability. Furthermore, although the processor contains protective circuitry to resist
damage from static electric discharge, one should always take precautions to avoid
static voltages or electric fields.

2.5 System Bus Signal Quality Specifications and
Measurement Guidelines
Overshoot (or undershoot) is the absolute value of the maximum voltage above the
nominal V
undershoot specifications limit transitions beyond V
edge rates. The processor can be permanently damaged by repeated overshoot or
undershoot events on any input, output, or I/O buffer if the charge is large enough
(that is, if the overshoot/undershoot is great enough). Determining the impact of an
overshoot/undershoot condition requires knowledge of the magnitude, the pulse
duration, and the activity factor (AF).
2.5.1 Overshoot/Undershoot Magnitude
Magnitude describes the maximum potential difference between a signal and its voltage
reference level. For the processor, both are referenced to GND, as shown in Figure 2-3.
It is important to note that overshoot and undershoot conditions are separate and their
impact must be determined independently. Overshoot/undershoot magnitude levels
must observe the absolute maximum specifications listed in Table 2-13 through
Table 2-17. These specifications must not be violated at any time, regardless of bus
activity or system state. Within these specifications are threshold levels that define
different allowed pulse duration. Provided that the magnitude of the overshoot/
undershoot is within the absolute maximum specifications, the pulse magnitude,
duration, and activity factors must all be used to determine if the overshoot/
undershoot pulse is within specifications.

/GND). The total time could

2.5.3 Activity Factor
Activity factor (AF) describes the frequency of overshoot (or undershoot) occurrence
relative to a clock. Since the highest frequency of assertion of any common clock signal
is every other clock, an AF = 1 indicates that the specific overshoot (or undershoot)
waveform occurs every other clock cycle. Thus, an AF = 0.01 indicates that the specific
overshoot (or undershoot) waveform occurs one time in every 200 clock cycles. For
source synchronous signals (data, and associated strobes), the activity factor is in
reference to the strobe edge. The highest frequency of assertion of any source
synchronous signal is every active edge of its associated strobe. So, an AF = 1
indicates that the specific overshoot (or undershoot) waveform occurs every other
strobe cycle. The specifications provided in Table 2-14 through Table 2-17 show the
maximum pulse duration allowed for a given overshoot/undershoot magnitude at a
specific activity factor. Each table entry is independent of all others, meaning that the
pulse duration reflects the existence of overshoot/undershoot events of that magnitude
ONLY. A platform with an overshoot/undershoot that just meets the pulse duration for a
specific magnitude where the AF <1, means that there can be no other overshoot/
undershoot events, even of lesser magnitude (if AF = 1, then the event occurs at all
times and no other events can occur).
Note: AF for the common clock AGTL+ signals is referenced to BCLKn, and BCLKp frequency.
The wired-OR Signals (BINIT#, HIT#, HITM#, BNR#, TND#, BERR#) are common
clock AGTL+ signals.
Note: AF for source synchronous (2x) signals is referenced to STBP#[7:0], and STBN#[7:0].
2.5.4 Reading Overshoot/Undershoot Specification Tables
The overshoot/undershoot specification for the processor is not a simple single value.
Instead, many factors are needed in order to correctly interpret the overshoot/
undershoot specification. In addition to the magnitude of the overshoot, the following
parameters must also be known: the width of the overshoot and the AF. To determine
the allowed overshoot for a particular overshoot event, the following must be done:
1. Determine the signal group that the particular signal falls into. For AGTL+ signals
operating in the 2x source synchronous domain, use Table 2-14 through
Table 2-16. If the signal is a wired-OR AGTL+ signal operating in the common clock
domain, use Table 2-15 through Table 2-17.
2. Determine the magnitude of the overshoot, or the undershoot (relative to GND).
3. Determine the activity factor (how often does this overshoot occur?).
4. Next, from the appropriate specification table, determine the maximum pulse
duration (in nanoseconds) allowed. The pulse duration shown in the table refers to
the period where either the maximum overshoot (for high phase) and undershoot
(for low phase) occurred.
24 Dual-Core Intel® Itanium® Processor 9000 and 9100 Series Datasheet
Electrical Specifications
5. Compare the specified maximum pulse duration to the signal being measured. If
the pulse duration measured is less than the pulse duration shown in the table,
then the signal meets the specifications.
6. Undershoot events must be analyzed separately from overshoot events, as they are
mutually exclusive.
2.5.5 Determining if a System Meets the Overshoot/Undershoot
Specifications
The overshoot/undershoot specifications listed in Table 2-13 through Table 2-17 specify
the allowable overshoot/undershoot for a single overshoot/undershoot event. However,
most systems will have multiple overshoot and/or undershoot events that each has
their own set of parameters (duration, AF and magnitude). While each overshoot on its
own may meet the overshoot specification, the total impact of all overshoot events may
cause the system to fail. A guideline to ensure a system passes the overshoot and
undershoot specifications is shown below:
1. Ensure that no signal ever exceeds V
2. If only one overshoot/undershoot event magnitude occurs, ensure that it meets the
specifications listed in Table 2-13 through Table 2-17.
3. If multiple overshoots and/or multiple undershoots occur, measure the worst-case
pulse duration for each magnitude and compare the results against the AF = 1
specifications. If all of these worst-case overshoot or undershoot events meet the
specifications (measured time < specifications) in the table (where AF = 1), then
the system passes.

or GND.
2.5.6 Wired-OR Signals
To ensure platform compatibility between the processors, system bus signals must
meet certain overshoot and undershoot requirements. The system bus wired-OR
signals (BINIT#, HIT#, HITM#, BNR#, TND#, BERR#) have the same absolute
overshoot and undershoot specification as the Source Synchronous AGTL+ Signals, but
they have different time-dependent overshoot/undershoot requirements.

2.7 System Bus Clock and Processor Clocking
The BCLKn and BCLKp inputs control the operating frequency of the processor system
bus interface. All processor system bus timing parameters are specified with respect to
the falling edge of BCLKn and rising edge of BCLKp. The address pins A[21:17]# will be
used to specify the system bus frequency during reset. The processor will ensure that
the correct bus/core ratio is elected based on the bus frequency that is specified during
reset.
Cold Reset Sequence:
• The configuration pins (A[21:17]#) must be asserted the entire time RESET# is
asserted.
• RESET# must be asserted before PWRGOOD is asserted.
• The duration from the assertion of PWRGOOD to the deassertion of RESET# must
be 1 millisecond minimum.
• After RESET# is deasserted, all the configuration, including pins A[21:17]#, must
remain valid for 2 BCLKs (minimum) to 3 BCLKs (maximum).
• BCLK is shown as a time reference to the BCLK period. It is not a requirement that
this is BCLKn or BCLKp signal.
• Configuration signals other than A[21:17]# must be asserted 4 BCLKs prior to the
deasserted edge of RESET# and must remain valid for 2 BCLKs (minimum) to 3
BCLKs (maximum) after the deasserted edge of RESET#.

This chapter describes the Dual-Core Intel Itanium processor 9000 and 9100 series
signals and pinout.
Note: The pins labeled “N/C” must remain unconnected. The processor uses a JEDEC
standard pin naming convention.
In this chapter, pin names are the actual names given to each physical pin of the
processor. System bus signal names are the names associated with the functions of
those pins. For those pins associated with multiple functions, their pin names and
system bus signal names are not necessarily identical.
Figure 3-1 shows the processor pin location diagram from the top view.

Thermal Specifications
5 Thermal Specifications
This chapter provides a description of the thermal features relating to the Dual-Core
Intel Itanium processor 9000 and 9100 series.
5.1 Thermal Features
The processor has an internal thermal circuit which senses when a certain temperature
is reached on the processor core. This circuit is used for controlling various thermal
states. In addition, an on-chip thermal diode is available for use by the thermal sensing
device on the processor. Figure 5-1 shows the relationship between temperature, time,
and the thermal alert, enhanced thermal management (ETM), and thermal trip points.
Note: Figure 5-1 is not intended to show a linear relationship in time or temperature as a
processor's thermal state advances from one state to the next state when the cooling
solution fails to control the processor temperature, as this is affected by many factors
such as cooling solution performance degradation and processor workload variations.
Figure 5-1. Dual-Core Intel® Itanium® Processor 9000 and 9100 Series Thermal Features
5.1.1 Thermal Alert
THRMALERT# is a programmable thermal alert signal which is part of the processor
system management feature. THRMALERT# is asserted when the measured
temperature from the processor thermal diode equals or exceeds the temperature
threshold data programmed in the high temp (THIGH) or low temp (TLOW) registers on
the sensor. Intel recommends using the upper temperature reference byte listed in the
Processor Information ROM when programming the THIGH register (see Chapter 6 for
more details). This signal can be used by the platform to implement thermal regulation
features such as generating an external interrupt to tell the operating system that the
processor core die temperature is increasing.

5.1.2 Enhanced Thermal Management
ETM is a power and thermal protection feature. On the Dual-Core Intel Itanium
processor 9000 and 9100 series, ETM uses power and thermal sensing devices on the
die to monitor entry points, indicating dangerous operation exceeding the thermal or
power specification. Once the sensing devices observe the temperature rising above
the power or thermal entry point, the processor will enter a low power mode of
execution and notify the system by sending a Correctable Machine Check Interrupt
(CMCI). The processor will remain in this low power mode until the power and
temperature decrease below the entry points and remain there for approximately one
second, at which point it will send another CMCI and resume normal operation. If the
power and temperature cannot be reduced, and continue to rise to critical levels, the
processor will assert Power Trip or Thermal Trip. The ETM feature may be disabled
through the PAL.
5.1.3 Power Trip
The Dual-Core Intel Itanium processor 9000 and 9100 series protects itself and the
MVR from catastrophic over power by use of an internal power sensor. The sensor trip
point is set above the normal operating power to ensure that there are no false trips.
The processor will signal a continuable MCA when the power draw exceeds a safe
operating level.
Thermal Specifications
Warning: Data will be lost if the MVR overheats and shuts down as a result of an extended over
power condition.
Once power trip is activated, the processor can continue operation, but may continue to
signal continuable MCAs as long as the over power condition exists.
5.1.4 Thermal Trip
The Dual-Core Intel Itanium processor 9000 and 9100 series protects itself from
catastrophic overheating by use of an internal thermal sensor. The sensor trip point is
set well above the normal operating temperature to ensure that there are no false trips.
The processor will stop all execution when the junction temperature exceeds a safe
operating level.
Warning: Data will be lost if the processor goes into thermal trip (signaled to the system by the
THRMTRIP# pin).
Once thermal trip is activated, the processor remains stopped until RESET# is asserted.
The processor case temperature must drop below the specified maximum before
issuing a reset to the processor. Please see Section 5.2 for details on case temperature.
5.2 Case Temperature
See Table 5-1 for the case temperature specifications for the Dual-Core Intel Itanium
processor 9000 and 9100 series. The case temperature is defined as the temperature
measured at the center of the top surface of the IHS.
Warning: Data may be lost if the case temperature exceeds the specified maximum.

System Management Feature Specifications
6 System Management Feature
Specifications
The Dual-Core Intel Itanium processor 9000 and 9100 series includes a system
management bus (SMBus) interface. This chapter describes the features of the SMBus
and SMBus components.
6.1 System Management Bus
6.1.1 System Management Bus Interface
The processor includes an Itanium processor family SMBus interface which allows
access to several processor features. The system management components on the
processor include two memory components (EEPROMs) and a thermal sensing device
(digital thermometer). The processor information EEPROM (PIROM) is programmed by
Intel with manufacturing and feature information specific to the Dual-Core Intel
Itanium processor 9000 and 9100 series. This information is permanently writeprotected. Section 6.2 provides details on the PIROM. The other EEPROM is a scratch
EEPROM that is available for other data at the system vendor’s discretion. The thermal
sensor can be used in conjunction with the information in the PIROM and/or the Scratch
EEPROM for system thermal monitoring and management. The thermal sensing device
on the processor provides an accurate means of acquiring an indicator of the junction
temperature of the processor core die. The thermal sensing device is connected to the
anode and cathode of the processor on-die thermal diode. SMBus implementation on
the processor uses the clock and data signals as defined by SMBus specifications.
6.1.2 System Management Interface Signals
Table 6-1 lists the system management interface signals and their descriptions. These
signals are used by the system to access the system management components via the
SMBus.
Table 6-1. System Management Interface Signal Descriptions
Signal Name Pin Count Description
3.3V 1 Voltage supply for EEPROMs and thermal sensor.

6.1.3 SMBus Device Addressing
Of the addresses broadcast across the SMBus, the memory components claim those of
the form “1010XXYZb”. The “XX” and “Y” bits are used to enable the devices on the
processor at adjacent addresses. The Y bit is hard-wired on the processor to GND (‘0’)
for the Scratch EEPROM and pulled to 3.3 V (‘1’) for the processor information ROM.
The “XX” bits are defined by the processor socket via the SMA0 and SMA1 pins on the
processor connector. These address pins have a weak pull-down (10 k ) to ensure that
the memory components are in a known state in systems which do not support the
SMBus, or only support a partial implementation. The “Z” bit is the read/write bit for
the serial bus transaction.
The thermal sensing device internally decodes one of three upper address patterns
from the bus of the form “0011XXXZb”, “1001XXXZb” or “0101XXXZb”. The device’s
addressing, as implemented, uses SMA2 and SMA1 and includes a Hi-Z state for the
SMA2 address pin. Therefore, the thermal sensing device supports six unique resulting
addresses. To set the Hi-Z state for SMA2, the pin must be left floating. The system
should drive SMA1 and SMA0, and will be pulled low (if not driven) by the 10 k pulldown resistor on the processor substrate. Attempting to drive either of these signals to
a Hi-Z state would cause ambiguity in the memory device address decode, possibly
resulting in the devices not responding, thus timing out or hanging the SMBus. As
before, the “Z” bit is the read/write bit for the serial bus transaction.
Figure 6-1 shows a logical diagram of the pin connections. Table 6-2 and Table 6-3
describe the address pin connections and how they affect the addressing of the
devices.
Note: Addresses of the form “0000XXXXb” are Reserved and should not be generated by an
SMBus master. Also, system management software must be aware of the processor
select in the address for the thermal sensing device.

6.3 Scratch EEPROM
Also available on the SMBus interface on the processor is an EEPROM which may be
used for other data at the system vendor’s discretion (Intel will not be using the scratch
EEPROM). The data in this EEPROM, once programmed, can be write-protected by
asserting the active-high SMWP signal. This signal has a weak pull-down (10 k ) to
allow the EEPROM to be programmed in systems with no implementation of this signal.
6.4 Processor Information ROM and Scratch EEPROM
Supported SMBus Transactions
The processor information ROM and scratch EEPROM responds to three of the SMBus
packet types: current address read, random address read, and sequential read.
Table 6-5 shows the format of the current address read SMBus packet. The internal
address counter keeps track of the address accessed during the last read or write
operation, incremented by one. Address “roll over” during reads is from the last byte of
the last eight byte page to the first byte of the first page. “Roll over” during writes is
from the last byte of the current eight byte page to the first byte of the same page.
Table 6-6 shows the format of the random read SMBus packet. The write with no data
loads the address desired to be read. Sequential reads may begin with a current
address read or a random address read. After the SMBus host controller receives the
data word, it responds with an acknowledge. This will continue until the SMBus host
controller responds with a negative acknowledge and a stop.
Table 6-7 shows the format of the byte write SMBus packet. The page write operates
the same way as the byte write, except that the SMBus host controller does not send a
stop after the first data byte and acknowledge. The Scratch EEPROM internally
increments its address. The SMBus host controller continues to transmit data bytes
until it terminates the sequence with a stop. All data bytes will result in an acknowledge
from the Scratch EEPROM. If more than eight bytes are written, the internal address
will “roll over” and the previous data will be overwritten.
In Table 6-5 through Table 6-7, ‘S’ represents the SMBus start bit, ‘P’ represents a stop
bit, ‘R’ represents a read, ‘W’ represents a write bit, ‘A’ represents an acknowledge, and
‘///’ represents a negative acknowledge. The shaded bits are transmitted by the
processor information ROM or Scratch EEPROM and the bits that are not shaded are
transmitted by the SMBus host controller. In the tables, the data addresses indicate
eight bits. The SMBus host controller should transmit eight bits, but as there are only
128 addresses, the most significant bit is a don’t care.

6.5 Thermal Sensing Device
The Dual-Core Intel Itanium processor 9000 and 9100 series thermal sensing device
provides a means of acquiring thermal data from the processor. The accuracy of the
thermal reading is expected to be better than ±5 °C. The thermal sensing device is
composed of control logic, SMBus interface logic, a precision analog to digital converter,
and a precision current source. The thermal sensing device drives a small current
through a thermal diode located on the processor core and measures the voltage
generated across the thermal diode by the current. With this information, the thermal
sensing device computes a byte of temperature data. Software running on the
processor or on a micro-controller can use the temperature data from the thermal
sensing device to thermally manage the system.
The thermal sensing device provides a register with a data byte (seven bits plus sign)
which contains a value corresponding to the sampled output of the thermal diode in the
processor core. The value of the byte read from the thermal sensor is always higher
than the actual processor core temperature; therefore, the offset from the reading
needs to be subtracted to obtain an accurate reading of the processor core
temperature. This data can be used in conjunction with the upper temperature
reference byte (provided in the Processor Information ROM) for thermal management
purposes. The temperature data from the thermal sensor can be read out digitally
using an SMBus read command (see Section 6.6). The thermal sensor detects when
SMBus power is applied to the processor, and resets itself at power-up.
Device
Address
R A Data /// P
The thermal sensing device also contains alarm registers to store thermal reference
threshold data. These values can be individually programmed on the thermal sensor. If
the measured temperature equals or exceeds the alarm threshold value, the
appropriate bit is set in the thermal sensing device status register, which is also
brought out to the processor system bus via the THRMALERT# signal (see
Section 6.1.1 for more details). At power-up, the appropriate alarm register values
need to be programmed into the thermal sensing device via the SMBus. It is
recommended that the upper thermal reference threshold byte (provided in the
processor information ROM) be used for setting the upper threshold value in the alarm
register. To account for the offset inherent in the thermal sensing device reading, the
actual programmed value of the upper threshold value in the alarm register should be
the sum of the upper thermal reference threshold byte and the thermal calibration
offset byte (both provided in the PIROM).
When polling the thermal sensing device on the processor to read the processor
temperatures, it is recommended that the polling frequency be every 0.5 to 1 second.

System Management Feature Specifications
6.6 Thermal Sensing Device Supported SMBus
Transactions
The thermal sensing device responds to five of the SMBus packet types: write byte,
read byte, send byte, receive byte, and alert response address (ARA). The send byte
packet is used for sending one-shot commands only. The receive byte packet accesses
the register commanded by the last read byte packet. If a receive byte packet was
preceded by a write byte or send byte packet more recently than a read byte packet,
then the behavior is undefined. Table 6-8 through Table 6-12 diagram the five packet
types. In these tables, ‘S’ represents the SMBus start bit, ‘P’ represents a stop bit, ‘Ack’
represents an acknowledge, and ‘///’ represents a negative acknowledge. The shaded
bits are transmitted by the thermal sensor and the unshaded bits are transmitted by
the SMBus host controller. Table 6-13 shows the encoding of the command byte.

6.7 Thermal Sensing Device Registers
The system management software can configure and control the thermal sensor by
writing to and interacting with different registers in the thermal sensor. These registers
include a thermal reference register, two thermal limit registers, a status register, a
configuration register, a conversion rate register, and other reserved registers. The
following subsections describe the registers in detail.
6.7.1 Thermal Reference Registers
The processor core and thermal sensing device internal thermal reference registers
contain the thermal reference value of the thermal sensing device and the processor
core thermal diodes. This value ranges from +127 to –128 decimal and is expressed as
a two’s complement, eight-bit number. These registers are saturating, that is, values
above 127 are represented at 127 decimal, and values below –128 are represented as
–128 decimal.
88 Dual-Core Intel® Itanium® Processor 9000 and 9100 Series Datasheet
System Management Feature Specifications
6.7.2 Thermal Limit Registers
The thermal sensing device has two thermal limit registers; they define high and low
limits for the processor core thermal diode. The encoding for these registers is the
same as for the thermal reference registers. If the diode thermal value equals or
exceeds one of its limits, then its alarm bit in the status register is triggered. This
indication is also brought out to the processor system bus via the THRMALERT# signal.
6.7.3 Status Register
The status register shown in Table 6-14 indicates which (if any) of the thermal value
thresholds have been exceeded. It also indicates if a conversion is in progress or if an
open circuit has been detected in the processor core thermal diode connection. Once
set, alarm bits stay set until they are cleared by a status register read. A successful
read to the status register will clear any alarm bits that may have been set, unless the
alarm condition persists. Note that the THRMALERT# interrupt signal is latched and is
not automatically cleared when the status flag bit is cleared. The latch is cleared by
sending the Alert Response Address (0001100) on the SMBus.

6.7.4 Configuration Register
The configuration register controls the operating mode (standby vs. auto-convert) of
the thermal sensing device. Table 6-15 shows the format of the configuration register.
If the RUN/STOP bit is set (high) then the thermal sensing device immediately stops
converting and enters standby mode. The thermal sensing device will still perform
analog-to-digital conversions in standby mode when it receives a one-shot command.
If the RUN/STOP bit is clear (low) then the thermal sensor enters auto-conversion
mode. The thermal sensing device starts operating in free running mode, autoconverting at 0.25 Hz after power-up.

6.7.5 Conversion Rate Register
The contents of the conversion rate register determine the nominal rate at which
analog-to-digital conversions happen when the thermal sensing device is in autoconvert mode. Table 6-16 shows the mapping between conversion rate register values
and the conversion rate. As indicated in Table 6-16, the conversion rate register is set
to its default state of 02h (0.25 Hz nominally) when the thermal sensing device is
powered-up. There is a ±25% error tolerance between the conversion rate indicated in
the conversion rate register and the actual conversion rate.

Signals Reference
A Signals Reference
This appendix provides an alphabetical listing of all Dual-Core Intel Itanium 9000 and
9100 series processor system bus signals. The tables at the end of this appendix
summarize the signals by direction: output, input, and I/O.
For a complete pinout listing including processor specific pins, please refer to
Chapter 3, “Pinout Specifications.”
A.1 Alphabetical Signals Reference
A.1.1 A[49:3]# (I/O)
The Address (A[49:3]#) signals, with byte enables, define a 250Byte physical memory
address space. When ADS# is active, these pins transmit the address of a transaction.
These pins are also used to transmit other transaction related information such as
transaction identifiers and external functions in the cycle following ADS# assertion.
These signals must connect the appropriate pins of all agents on the processor system
bus. The A[49:27]# signals are parity-protected by the AP1# parity signal, and the
A[26:3]# signals are parity-protected by the AP0# parity signal.
On the active-to-inactive transition of RESET#, the processors sample the A[49:3]#
pins to determine their power-on configuration.
A.1.2 A20M# (I)
A20M# is no connect and is ignored in the processor system environment.
A.1.3 ADS# (I/O)
The Address Strobe (ADS#) signal is asserted to indicate the validity of the transaction
address on the A[49:3]#, REQ[5:0]#, AP[1:0]# and RP#pins. All bus agents observe
the ADS# activation to begin parity checking, protocol checking, address decode,
internal snoop, or deferred reply ID match operations associated with the new
transaction.
A.1.4 AP[1:0]# (I/O)
The Address Parity (AP[1:0]#) signals can be driven by the request initiator along with
ADS# and A[49:3]#. AP[1]# covers A[49:27]#, and AP[0]# covers A[26:3]#. A
correct parity signal is high if an even number of covered signals are low and low if an
odd number of covered signals are low. This allows parity to be high when all the
covered signals are high.
A.1.5 ASZ[1:0]# (I/O)
The ASZ[1:0]# signals are the memory address-space size signals. They are driven by
the request initiator during the first Request Phase clock on the REQa[4:3]# pins. The
ASZ[1:0]# signals are valid only when REQa[2:1]# signals equal 01B, 10B, or 11B,
indicating a memory access transaction. The ASZ[1:0]# decode is defined in Table A-1.

Any memory access transaction addressing a memory region that is less than 64 GB
(that is, Aa[49:36]# are all zeroes) must set ASZ[1:0]# to 01. Any memory access
transaction addressing a memory region that is equal to or greater than 64 GB (that is,
Aa[49:36]# are not all zeroes) must set ASZ[1:0]# to 10. All observing bus agents
that support the 64 GByte (36-bit) address space must respond to the transaction
when ASZ[1:0]# equals 01. All observing bus agents that support larger than the 64
GByte (36-bit) address space must respond to the transaction when ASZ[1:0]# equals
01 or 10.
A.1.6 ATTR[3:0]# (I/O)
The ATTR[3:0]# signals are the attribute signals. They are driven by the request
initiator during the second clock of the Request Phase on the Ab[35:32]# pins. The
ATTR[3:0]# signals are valid for all transactions. The ATTR[3]# signal is reserved. The
ATTR[2:0]# are driven based on the memory type. Please refer to Table A-2.

A.1.7 BCLKp/BCLKn (I)
The BCLKp and BCLKn differential clock signals determine the bus frequency. All agents
drive their outputs and latch their inputs on the differential crossing of BCLKp and
BCLKn on the signals that are using the common clock latched protocol.
BCLKp and BCLKn indirectly determine the internal clock frequency of the processor.
Each processor derives its internal clock by multiplying the BCLKp and BCLKn
frequency by a ratio that is defined and allowed by the power-on configuration.
A.1.8 BE[7:0]# (I/O)
The BE[7:0]# signals are the byte-enable signals for partial transactions. They are
driven by the request initiator during the second Request Phase clock on the Ab[15:8]#
pins.
92 Dual-Core Intel® Itanium® Processor 9000 and 9100 Series Datasheet
Signals Reference
For memory or I/O transactions, the byte-enable signals indicate that valid data is
requested or being transferred on the corresponding byte on the 128-bit data bus.
BE[0]# indicates that the least significant byte is valid, and BE[7]# indicates that the
most significant byte is valid. Since BE[7:0]# specifies the validity of only 8 bytes on
the 16 byte wide bus, A[3]# is used to determine which half of the data bus is validated
by BE[7:0]#.
For special transactions ((REQa[5:0]# = 001000B) and (REQb[1:0]# = 01B)), the
BE[7:0]# signals carry special cycle encodings as defined in Table A-3. All other
encodings are reserved.

For Deferred Reply transactions, BE[7:0]# signals are reserved. The Defer Phase
transfer length is always the same length as that specified in the Request Phase except
the Bus Invalidate Line (BIL) transaction.
A BIL transaction may return one cache line (128 bytes).
A.1.9 BERR# (I/O)
The Bus Error (BERR#) signal can be asserted to indicate a recoverable error with
global MCA. BERR# assertion conditions are configurable at the system level.
Configuration options enable BERR# to be driven as follows:
• Asserted by the requesting agent of a bus transaction after it observes an internal
error.
• Asserted by any bus agent when it observes an error in a bus transaction.
When the bus agent samples an asserted BERR# signal and BERR# sampling is
enabled, the processor enters a Machine Check Handler.
BERR# is a wired-OR signal to allow multiple bus agents to drive it at the same time.
Dual-Core Intel® Itanium® Processor 9000 and 9100 Series Datasheet 93
A.1.10 BINIT# (I/O)
If enabled by configuration, the Bus Initialization (BINIT#) signal is asserted to signal
any bus condition that prevents reliable future operation.
If BINIT# observation is enabled during power-on configuration, and BINIT# is
sampled asserted, all bus state machines are reset. All agents reset their rotating IDs
for bus arbitration to the same state as that after reset, and internal count information
is lost. The L2 and L3 caches are not affected.
If BINIT# observation is disabled during power-on configuration, BINIT# is ignored by
all bus agents with the exception of the priority agent. The priority agent must handle
the error in a manner that is appropriate to the system architecture.
BINIT# is a wired-OR signal.
A.1.11 BNR# (I/O)
The Block Next Request (BNR#) signal is used to assert a bus stall by any bus agent
that is unable to accept new bus transactions to avoid an internal transaction queue
overflow. During a bus stall, the current bus owner cannot issue any new transactions.
Since multiple agents might need to request a bus stall at the same time, BNR# is a
wired-OR signal. In order to avoid wired-OR glitches associated with simultaneous edge
transitions driven by multiple drivers, BNR# is asserted and sampled on specific clock
edges.
Signals Reference
A.1.12 BPM[5:0]# (I/O)
The BPM[5:0]# signals are system support signals used for inserting breakpoints and
for performance monitoring. They can be configured as outputs from the processor that
indicate programmable counters used for monitoring performance, or inputs from the
processor to indicate the status of breakpoints.
A.1.13 BPRI# (I)
The Bus Priority-agent Request (BPRI#) signal is used by the priority agent to arbitrate
for ownership of the system bus. Observing BPRI# asserted causes all other agents to
stop issuing new requests, unless such requests are part of an ongoing locked
operation.The priority agent keeps BPRI# asserted until all of its requests are
completed, then releases the bus by deasserting BPRI#.
A.1.14 BR[0]# (I/O) and BR[3:1]# (I)
BR[3:0]# are the physical bus request pins that drive the BREQ[3:0]# signals in the
system. The BREQ[3:0]# signals are interconnected in a rotating manner to individual
processor pins. Table A-4 and Table A-4 give the rotating interconnection between the
processor and bus signals for both the 4P and 2P system bus topologies.

During power-on configuration, the priority agent must assert the BR[0]# bus signal.
All symmetric agents sample their BR[3:0]# pins on asserted-to-deasserted transition
of RESET#. The pin on which the agent samples an asserted level determines its agent
ID. All agents then configure their pins to match the appropriate bus signal protocol as
shown in Table A-6.

Arbitration ID
A.1.15 BREQ[3:0]# (I/O)
The BREQ[3:0]# signals are the symmetric agent arbitration bus signals (called bus
request). A symmetric agent n arbitrates for the bus by asserting its BREQn# signal.
Agent n drives BREQn# as an output and receives the remaining BREQ[3:0]# signals
as inputs.
The symmetric agents support distributed arbitration based on a round-robin
mechanism. The rotating ID is an internal state used by all symmetric agents to track
the agent with the lowest priority at the next arbitration event. At power-on, the
rotating ID is initialized to three, allowing agent 0 to be the highest priority symmetric
agent. After a new arbitration event, the rotating ID of all symmetric agents is updated
to the agent ID of the symmetric owner. This update gives the new symmetric owner
lowest priority in the next arbitration event.
A new arbitration event occurs either when a symmetric agent asserts its BREQn# on
an Idle bus (all BREQ[3:0]# previously deasserted), or the current symmetric owner
deasserts BREQn# to release the bus ownership to a new bus owner n. On a new
arbitration event, all symmetric agents simultaneously determine the new symmetric
owner using BREQ[3:0]# and the rotating ID. The symmetric owner can park on the
bus (hold the bus) provided that no other symmetric agent is requesting its use. The
symmetric owner parks by keeping its BREQn# signal asserted. On sampling BREQn#
asserted by another symmetric agent, the symmetric owner deasserts BREQn# as soon
as possible to release the bus. A symmetric owner stops issuing new requests that are
not part of an existing locked operation on observing BPRI# asserted.
Agent ID
Reported
Dual-Core Intel® Itanium® Processor 9000 and 9100 Series Datasheet 95
A symmetric agent can deassert BREQn# before it becomes a symmetric owner. A
symmetric agent can reassert BREQn# after keeping it deasserted for one clock.
A.1.16 CCL# (I/O)
CCL# is the Cache Cleanse signal. It is driven on the second clock of the Request Phase
on the EXF[2]#/Ab[5]# pin. CCL# is asserted for Memory Write transaction to indicate
that a modified line in a processor may be written to memory without being invalidated
in its caches.
A.1.17 CPUPRES# (O)
CPUPRES# can be used to detect the presence of a processor in a socket. A ground
indicates that a processor is installed, while an open indicates that a processor is not
installed.
A.1.18 D[127:0]# (I/O)
The Data (D[127:0]#) signals provide a 128-bit data path between various system bus
agents. Partial transfers require one data transfer clock with valid data on the byte(s)
indicated by asserted byte enables BE[7:0]# and A[3]#. Data signals that are not valid
for a particular transfer must still have correct ECC (if data bus error checking is
enabled). The data driver asserts DRDY# to indicate a valid data transfer.
Signals Reference
A.1.19 D/C# (I/O)
The Data/Code (D/C#) signal is used to indicate data (1) or code (0) on REQa[1]#,
only during Memory Read transactions.
A.1.20 DBSY# (I/O)
The Data Bus Busy (DBSY#) signal is asserted by the agent that is responsible for
driving data on the system bus to indicate that the data bus is in use. The data bus is
released after DBSY# is deasserted.
DBSY# is replicated three times to enable partitioning of the data paths in the system
agents. This copy of the Data Bus Busy signal (DBSY#) is an input as well as an output.
A.1.21 DBSY_C1# (O)
DBSY# is a copy of the Data Bus Busy signal. This copy of the Data Bus Busy signal
(DBSY_C1#) is an output only.
A.1.22 DBSY_C2# (O)
DBSY# is a copy of the Data Bus Busy signal. This copy of the Data Bus Busy signal
(DBSY_C2#) is an output only.
A.1.23 DEFER# (I)
The DEFER# signal is asserted by an agent to indicate that the transaction cannot be
guaranteed in-order completion. Assertion of DEFER# is normally the responsibility of
the priority agent.

Signals Reference
A.1.24 DEN# (I/O)
The Defer Enable (DEN#) signal is driven on the bus on the second clock of the Request
Phase on the Ab[4]# pin. DEN# is asserted to indicate that the transaction can be
deferred by the responding agent.
A.1.25 DEP[15:0]# (I/O)
The Data Bus ECC Protection (DEP[15:0]#) signals provide optional ECC protection for
Data Bus (D[127:0]#). They are driven by the agent responsible for driving
D[127:0]#. During power-on configuration, bus agents can be enabled for either ECC
checking or no checking.
The ECC error correcting code can detect and correct single-bit errors and detect
double-bit or nibble errors.
A.1.26 DHIT# (I)
The Deferred Hit (DHIT#) signal is driven during the Deferred Phase by the deferring
agent. For read transactions on the bus DHIT# returns the final cache status that would
have been indicated on HIT# for a transaction which was not deferred. DID[9:0]# (I/
O)
DID[9:0]# are Deferred Identifier signals. The requesting agent transfers these signals
by using A[25:16]#. They are transferred on Ab[25:16]# during the second clock of
the Request Phase on all transactions, but Ab[20:16]# is only defined for deferrable
transactions (DEN# asserted). DID[9:0]# is also transferred on Aa[25:16]# during the
first clock of the Request Phase for Deferred Reply transactions.
The Deferred Identifier defines the token supplied by the requesting agent. DID[9]#
and DID[8:5]# carry the agent identifiers of the requesting agents (always valid) and
DID[4:0]# carry a transaction identifier associated with the request (valid only with
DEN# asserted). This configuration limits the bus specification to 32 logical bus agents
with each one of the bus agents capable of making up to 32 requests. Table A-7 shows
the DID encodings.
Table A-7. DID[9:0]# Encoding
DID[9]# DID[8:5]# DID[4:0]#
Agent Type Agent ID[3:0] Transaction ID[4:0]
DID[9]# indicates the agent type. Symmetric agents use 0. Priority agents use 1.
DID[8:5]# indicates the agent ID. Symmetric agents use their arbitration ID.
DID[4:0]# indicates the transaction ID for an agent. The transaction ID must be
unique for all deferrable transactions issued by an agent which have not reported their
snoop results.
The Deferred Reply agent transmits the DID[9:0]# (Ab[25:16]#) signals received
during the original transaction on the Aa[25:16]# signals during the Deferred Reply
transaction. This process enables the original requesting agent to make an identifier
match with the original request that is awaiting completion.
Dual-Core Intel® Itanium® Processor 9000 and 9100 Series Datasheet 97
A.1.27 DPS# (I/O)
The Deferred Phase Enable (DPS#) signal is driven to the bus on the second clock of
the Request Phase on the Ab[3]# pin. DPS# is asserted if a requesting agent supports
transaction completion using the Deferred Phase. A requesting agent that supports the
Deferred Phase will always assert DPS#. A requesting agent that does not support the
Deferred Phase will always deassert DPS#.
A.1.28 DRDY# (I/O)
The Data Ready (DRDY#) signal is asserted by the data driver on each data transfer,
indicating valid data on the data bus. In a multi-cycle data transfer, DRDY# can be
deasserted to insert idle clocks.
DRDY# is replicated three times to enable partitioning of data paths in the system
agents. This copy of the Data Ready signal (DRDY#) is an input as well as an output.
A.1.29 DRDY_C1# (O)
DRDY# is a copy of the Data Ready signal. This copy of the Data Phase data-ready
signal (DRDY_C1#) is an output only.

DRDY# is a copy of the Data Ready signal. This copy of the Data Phase data-ready
signal (DRDY_C2#) is an output only.
A.1.31 DSZ[1:0]# (I/O)
The Data Size (DSZ[1:0]#) signals are transferred on REQb[4:3]# signals in the
second clock of the Request Phase by the requesting agent. The DSZ[1:0]# signals
define the data transfer capability of the requesting agent. For the processor, DSZ# =
01, always.
A.1.32 EXF[4:0]# (I/O)
The Extended Function (EXF[4:0]#) signals are transferred on the A[7:3]# pins by the
requesting agent during the second clock of the Request Phase. The signals specify any
special functional requirement associated with the transaction based on the requestor
mode or capability. The signals are defined in Table A-8.

A.1.33 FCL# (I/O)
The Flush Cache Line (FCL#) signal is driven to the bus on the second clock of the
Request Phase on the A[6]# pin. FCL# is asserted to indicate that the memory
transaction is initiated by the global Flush Cache () instruction.
A.1.34 FERR# (O)
The FERR# signal may be asserted to indicate a processor detected error when IERR
mode is enabled. If IERR mode is disabled, the FERR# signal will not be asserted in the
processor system environment.
A.1.35 GSEQ# (I)
Assertion of the Guaranteed Sequentiality (GSEQ#) signal indicates that the platform
guarantees completion of the transaction without a retry while maintaining
sequentiality.
A.1.36 HIT# (I/O) and HITM# (I/O)
The Snoop Hit (HIT#) and Hit Modified (HITM#) signals convey transaction snoop
operation results. Any bus agent can assert both HIT# and HITM# together to indicate
that it requires a snoop stall. The stall can be continued by reasserting HIT# and
HITM# together.
A.1.37 ID[9:0]# (I)
The Transaction ID (ID[9:0]#) signals are driven by the deferring agent. The signals in
the two clocks are referenced IDa[9:0]# and IDb[9:0]#. During both clocks, ID[9:0]#
signals are protected by the IP0# parity signal for the first clock, and by the IP[1]#
parity signal on the second clock.
IDa[9:0]# returns the ID of the deferred transaction which was sent on Ab[25:16]#
(DID[9:0]#).
A.1.38 IDS# (I)
The ID Strobe (IDS#) signal is asserted to indicate the validity of ID[9:0]# in that clock
and the validity of DHIT# and IP[1:0]# in the next clock.
A.1.39 IGNNE# (I)
IGNNE# is no connect and is ignored in the processor system environment.
A.1.40 INIT# (I)
The Initialization (INIT#) signal triggers an unmasked interrupt to the processor. INIT#
is usually used to break into hanging or idle processor states. Semantics required for
platform compatibility are supplied in the PAL firmware interrupt service routine.

A.1.41 INT (I)
INT is the 8259-compatible Interrupt Request signal which indicates that an external
interrupt has been generated. The interrupt is maskable. The processor vectors to the
interrupt handler after the current instruction execution has been completed. An
interrupt acknowledge transaction is generated by the processor to obtain the interrupt
vector from the interrupt controller.
The LINT[0] pin can be software configured to be used either as the INT signal or
another local interrupt.
A.1.42 IP[1:0]# (I)
The ID Parity (IP[1:0]#) signals are driven on the second clock of the Deferred Phase
by the deferring agent. IP0# protects the IDa[9:0]# and IDS# signals for the first
clock, and IP[1]# protects the IDb[9:2, 0]# and IDS# signals on the second clock.
A.1.43 LEN[2:0]# (I/O)
The Data Length (LEN[2:0]#) signals are transmitted using REQb[2:0]# signals by the
requesting agent in the second clock of Request Phase. LEN[2:0]# defines the length of
the data transfer requested by the requesting agent as shown in Table A-9. The
LEN[2:0]#, HITM#, and RS[2:0]# signals together define the length of the actual data
transfer.
