Caches, and Their Invalidation
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, for example, 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.
QDF Number is a four digit code used to distinguish between engineering samples.
These samples are used for qualification and early design validation. The functionality
of these parts can range from mechanical only to fully functional. This document has a
processor identification information table that lists these QDF numbers and the
corresponding product details.
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.
