Defensive Design of Saturating Counters Based on Differential Privacy. (arXiv:2206.00279v1 [cs.CR])

The saturating counter is the basic module of the dynamic branch predictor,
which involves the core technique to improve instruction level parallelism
performance in modern processors. However, most studies focus on the
performance improvement and hardware consumption of saturating counters, while
ignoring the security problems they may cause. In this paper, we creatively
propose to study and design saturating counters from the defense perspective of
differential privacy, so that attackers cannot distinguish the states that
saturating counters are in and …
