Introduction
1Introduction
1.1 Overview
The Intel®Itanium®Processor 9300 Series and Intel®Itanium®Processor 9500 Series
employ 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 designed 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 run-time 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 Intel®Itanium®Processor 9300 Series and Intel®Itanium®Processor 9500 Series
system interface, with its 4 full width and 2 half width Intel®QuickPath Interconnects,
enables each processor to directly connect to other system components, thus 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 Intel®Itanium®Processor 9300 Series and Intel®Itanium®Processor 9500 Series
are pin compatible and support a range of computing needs and configurations from a
2-way to large SMP servers (although OEM field upgrade methodologies vary). This
document provides the electrical, mechanical and thermal specifications that must be
met when using the Intel®Itanium®Processor 9300 Series and Intel®Itanium®
Processor 9500 Series in your systems.

Introduction
14 Intel®Itanium®Processor 9300 Series and 9500 Series Datasheet
The Intel®Itanium®Processor 9500 Series delivers increased levels of flexibility,
reliability, performance, and cost-effective scalability for your most data-intensive
business and technical applications.
The Intel®Itanium®Processor 9500 Series processor provides up to 32 megabytes LLC
cache, Hyper-Threading Technology for increased performance, Intel®Virtualization
Technology for improved virtualization, Intel®Cache Safe Technology for increased
availability. Intel®Turbo Boost Technology, featuring sustained boost. The Intel®
Itanium®Processor 9500 Series employs advanced power monitoring and control to
deliver a higher processor frequency at all times, for maximum performance on all
workloads. The result is a higher thermal envelope utilization for more overall
performance. The Intel®Itanium®Processor 9500 Series offers large cache arrays
covered by ECC including the large LLC utilizing double correct/triple detect (DECTED)
and protecting the MLI/MLD with in-line single correct/double detect (SECDED). In
addition, the processor provides extensive parity protection and parity interleaving on
nearly all RFs, end-to-end parity protection with recovery-support on all critical internal
buses and data paths including the ring. Residue protection on Floating Point unit,
along with the adoption of radiation-hardened (RAD) sequential latching elements for
vulnerable architectural and state. The Intel®Itanium®Processor 9500 Series
processor interfaces exclusively with the Ararat II Voltage Regulator Module.
The Intel®Itanium®Processor 9500 Series consists of up to 8 core processors and a
system interface unit. Each processor core provides a 12-wide, 11-stage deep
execution pipeline. The resources consist of six integer units, one integer multiply unit,
four multimedia units, two load/store units, three branch units and two floating-point
units each capable of extended, double and single precision arithmetic. The hardware
employs dynamic prefetch, branch prediction, a register scoreboard, and non-blocking
caches to optimize for compile-time non-determinism. 32 additional stacked general
registers are provided over the Intel®Itanium®Processor 9300 Series, and hardware
support is provided for denormal, unnormal, and pseudo-normal operands for floating
point software assist offloading.
New instructions on the Intel®Itanium®Processor 9500 Series simplify common tasks.
They include: clz (count leading zeros), mpy4 and mpyshl4(unsigned integer multiply/
shift and multiply), mov-to-DAHR/mv-from-DAHR (for improved MLD/FLD prefetcher
hinting and performance), and hint@priority (used by the processor to temporarily
allocate more resources to a thread). Advanced Explicitly Parallel Instruction
Computing (EPIC) is enhanced on the Intel®Itanium®Processor 9500 Series by
increasing the capacity of retiring instructions per cycle from 6 to a maximum of 12
instructions per cycle per core.
Intel®Hyper-threading Technology is enhanced in the Intel®Itanium®Processor 9500
Series with dual domain multithreading, which enables independent front-end and
back-end pipeline execution to improve multi-thread efficiency and performance for
both new and legacy applications. It provides hardware support for two threads per
core, with a threaded 96 entry per thread Instruction Buffer and threaded MLDTLB and
FLDTLB, and a dedicated load return path from the MLD to the integer register file.
Three levels of on-die cache minimize overall memory latency, with 16 KB instruction
cache FLI/16 KB write-through data cache FLD that comprise the FLC and 512 KB MLI/
256 KB writeback data cache MLD that comprise the MLC.
The Intel®Itanium®Processor 9500 Series offers a new RAS feature: Intel®
Instruction Replay Technology. Pipeline replay resolves stall conditions that occur when
the microprocessor pipeline encounters a resource hazard that prevents immediate
execution. In a replay, the instruction that encountered the resource hazard is removed
from the pipeline, along with all the instructions that come after it. The instruction is
then read again out of the instruction buffer for replay and re-executed. To ensure a

Intel®Itanium®Processor 9300 Series and 9500 Series Datasheet 15
Introduction
replay can be initiated for any instruction in the pipeline that encounters a resource
hazard, a copy of each instruction is maintained in the instruction buffer until the
instruction has successfully traversed the pipeline and is no longer needed. If
necessary, an instruction can replay multiple times. As a result, Intel®Instruction
Replay Technology automatically detects and many corrects soft errors in the
instruction pipeline. With this technology, soft errors can be identified and corrected in
as few as seven clock cycles, which is fast enough to be invisible to the software
running on the platform.
1.2 Architectural Overview
The sections below give an overview of the Intel®Itanium®Processor 9300 Series and
Intel®Itanium®Processor 9500 Series.
1.2.1 Intel®Itanium®Processor 9300 Series Overview
The Intel®Itanium®Processor 9300 Series processor is a quad-core architecture. It
supports up to four processor cores, each with its own L3, L2, and L1 level cache. Also
supported are the following page sizes for purges or inserts: 4K, 8K, 16K, 64K, 256K,
1M, 4M, 16M, 64M, 256M, 1G, 4G.
The architecture interfacing the cores to the system is referred to as the System
Interface. Each processor core has it own Caching Agent (CPE). The CPE interfaces
between the processor core and the Intel QuickPath Interconnect. The Intel®Itanium®
Processor 9300 Series processor has two Home Agents (Bbox). The Bbox interfaces
between the memory controller and the Intel®QuickPath Interconnect and supports a
directory cache. Each Bbox interfaces with a memory controllers (Zbox). Each memory
controller supports two Intel SMI in lockstep. The Intel SMI are the interconnects to
Intel®7500 Scalable Memory Buffer. The processor supports six Intel QuickPath
Interconnects at the socket, four full width and two half width. The Caching Agent,
Home Agent, and Intel QuickPath Interconnects are connected via a 12-port Crossbar
Router, each port supporting the Intel QuickPath Interconnect protocol. Figure 1-1
shows the Intel®Itanium®Processor 9300 Series block diagram.
The Intel QPI viral and poison fields are used to flag corrupted system state and bad
data accordingly. Once it has “gone viral”, an Intel QPI agent will set the viral field
within all packet headers. Viral mode is entered in three ways: receiving a viral packet,
upon a detecting fatal/panic error, or when a global viral signal (from Cboxes) is
asserted. Viral is cleared on Reset. Poisoning is used to indicate bad data on a per-flit
basis. Poison does not indicate corrupted system coherency, but rather that a particular
block of data is not reliable.

1.2.2 Intel®Itanium®Processor 9500 Series Overview
The Intel®Itanium®Processor 9500 Series is an eight core architecture. It supports up
to eight cores, each with its own First Level Cache (FLC) and Mid Level Cache (MLC),
both of which are split into instruction and data caches (FLI/FLD and MLI/MLD,
respectively). The Last Level Cache (LLC) is shared among the cores and supports up to
32 MB. Also supported are the following page sizes for purges or inserts: 4K, 8K, 16K,
64K, 256K, 1M, 4M, 16M, 64M, 256M, 1G, 4G.
The architecture interfacing the cores to the system is referred to as the uncore. Each
Intel®Itanium®Processor 9500 Series core interfaces to the Ring. The Ring provides
connectivity to the Last Level Cache via the Cache Controllers (Cboxes). The Ring also
provides connectivity to Intel QPI via Ring/Sbox. The Sbox and Cbox provide the
supports for the two Intel QPI Caching Agents. The processor has two Home Agents
(Bbox). The Bbox interfaces between the memory controller and the Intel®QuickPath
Interconnect and supports a directory cache. Each memory controller supports two
Intel®Scalable Memory Interconnects (Intel®SMI) in lockstep. The Intel SMI are the
interconnects to Scalable Memory Buffer. The Intel®Itanium®Processor 9500 Series
processor supports six Intel®QuickPath Interconnects at the socket, four full width and
two half width. The Caching Agent, Home Agent, and Intel®QuickPath Interconnects
are connected via a 10-port Crossbar Router, each port supporting the Intel®QuickPath
Interconnect protocol. Figure 1-2 shows the processor block diagram.

Introduction
The Intel QPI viral and poison fields are used to flag corrupted system state and bad
data accordingly. Once it has “gone viral”, an Intel QPI agent will set the viral field
within all packet headers. Viral mode is entered in three ways: receiving a viral packet,
upon a detecting fatal/panic error, or when a global viral signal (from Cboxes) is
asserted. Viral is cleared on Reset. Poisoning is used to indicate bad data on a per-flit
basis. Poison does not indicate corrupted system coherency, but rather that a particular
block of data is not reliable.
Intel®Itanium®Processor 9500 Series PAL's Demand Based Switching (DBS) support
includes implementations of Power/Performance states (P-states) and Halt states (C-
states). For the PAL Halt state interface and architected specifications of the PAL P-
state interface, see the Intel®Itanium®Architecture Software Developer's Manual,
Volume 2, Section 11.6. PAL controls the Intel®Itanium®Processor 9500 Series
processor power through a special built-in microcontroller that manipulates voltage and
frequency. PAL communicates requested P-states to this controller through internal
registers.
As shown in Figure 1-3, Itanium architecture-based firmware consists of several major
components: Processor Abstraction Layer (PAL), System Abstraction Layer (SAL),
Unified Extensible Firmware Interface (UEFI) and Advanced Configuration and Power
Interface (ACPI). PAL, SAL, UEFI and ACPI together provide processor and system
initialization for an operating system boot. PAL and SAL provide machine check abort
handling. PAL, SAL, UEFI and ACPI provide various run-time services for system
functions which may vary across implementations. The interactions of the various
services that PAL, SAL, UEFI and ACPI provide are illustrated in Figure 1-3. In the
context of this model and throughout the rest of this chapter, the System Abstraction
Layer (SAL) is a firmware layer which isolates operating system and other higher level
software from implementation differences in the platform, while PAL is the firmware
layer that abstracts the processor implementation.

Introduction
18 Intel®Itanium®Processor 9300 Series and 9500 Series Datasheet
Protection Keys provide a method to restrict permission by tagging each virtual page
with a unique protection domain identifier. The Protection Key Registers (PKR)
represent a register cache of all protection keys required by a process. The operating
system is responsible for management and replacement polices of the protection key
cache. Before a memory access (including IA-32) is permitted, the processor compares
a translation’s key value against all keys contained in the PKRs. If a matching key is not
found, the processor raises a Key Miss fault. If a matching Key is found, access to the
page is qualified by additional read, write and execute protection checks specified by
the matching protection key register. If these checks fail, a Key Permission fault is
raised. Upon receipt of a Key Miss or Key Permission fault, software can implement the
desired security policy for the protection domain. Some processor models may
implement additional protection key registers and protection key bits. Unimplemented
bits and registers are reserved. Please see the processor-specific documentation for
further information on the number of protection key registers and protection key bits
implemented on the processor.

1.4 Processor Abstraction Layer
The Intel®Itanium®Processor 9300 Series and Intel®Itanium®Processor 9500 Series
require implementation-specific 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.
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.
1.5 Mixing Processors of Different Frequencies and
Cache Sizes
All Intel®Itanium®Processor 9300 Series processors and Intel®Itanium®Processor
9500 Series in the same system partition are required to have the same last level
cache size and identical core frequency. Mixing processors of different core frequencies,
cache sizes, and mixing Intel®Itanium®Processor 9300 Series with Intel®Itanium®
Processor 9500 Series is not supported and has not been validated by Intel. Operating
system support for multiprocessing with mixed components should also be considered.
1.6 Terminology
In this document, “the processor” refers to the Intel®Itanium®Processor 9300 Series
and/or Intel®Itanium®Processor 9500 Series, unless otherwise indicated.
An ‘_N’ notation 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_N 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
