Specification Update 7
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 such as, 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, and so
on).
