Nomenclature
Errata
are design defects or errors. These may cause the processor 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.
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. Read all notes associated with
each S-Spec number.
Specification Changes
are modifications to the current published specifications. These
changes will be incorporated in any new release of the specification.
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 any new release of the specification.
Documentation Changes
include typos, errors, or omissions from the current published
specifications. These will be incorporated in any new release of the specification.
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.).
