 Processor 9000 and 9100 Series Datasheet
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

System Abstraction Layer Specification.

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.

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
core
, or a capitalized, abbreviated subscript, for example, T
CO
.
