Claims
1
An apparatus comprising:
a register tracker to generate a pre-computation slice; and
a pre-computation engine to execute the pre-computation slice.
Relevance
see 5933630. "superfectch" and "prefetch" features from Microsoft Windows Vista and XP were alledgely covered by the '630 claims which also seem to be covered under this general independent claim 1.
