Nomenclature
S-Spec Number
is a five-digit code used to identify products. Products are
differentiated by their unique characteristics (e.g., core speed, L2 cache size, package
type, etc.) as described in the processor identification information table. Care should
be taken to read all notes associated with each S-Spec number
QDF Number
is a several digit code that is used to distinguish between engineering
samples. These processors are used for qualification and early design validation. The
functionality of these parts can range from mechanical only to fully functional. The
NDA specification update has a processor identification information table that lists
these QDF numbers and the corresponding product sample details.
Errata
are design defects or errors. Errata may cause the processor’s behavior to
deviate from published specifications. Hardware and software designed to be used
with any given stepping must assume that all errata documented for that stepping are
present on all devices.
Specification Changes
are modifications to the current published specifications.
These changes will be incorporated in the next release of the specifications.
Specification Clarifications
describe a specification in greater detail or further
highlight a specification’s impact to a complex design situation. These clarifications will
be incorporated in the next release of the specifications.
Documentation Changes
include typos, errors, or omissions from the current
published specifications. These changes will be incorporated in the next release of the
specifications.
Note:
Errata remain in the specification update throughout the product’s lifecycle, or until a
particular stepping is no longer commercially available. Under these circumstances,
errata removed from the specification update are archived and available upon
request. Specification changes, specification clarifications and documentation changes
are removed from the specification update when the appropriate changes are made to
the appropriate product specification or user documentation (datasheets, manuals,
etc.).
