Dynamic power gating with quality guarantees

Power gating is usually driven by a predictive control, and frequent mispredictions can counter-productively lead to a large increase in energy consumption. This energy vulnerability could be exploited by malicious applications such as a power virus, or it may be exposed by regular applications containing repetitive mispredictions patterns. We propose counteracting this vulnerability by using a guard mechanism to prevent power overruns. Categories and Subject Descriptors
