Self-tuning dynamic voltage scaling techniques for processor design
The Dynamic Voltage Scaling (DVS) technique has proven to be ideal in regard to balancing performance and energy consumption of a processor since it allows for almost cubic reduction in dynamic power consumption with only a nearly linear reduction in performance. Due to its virtue, the DVS …

Design and Analysis of an Adaptive Asynchronous System Architecture for Energy Efficiency
… while maintaining performance. The use of dynamic voltage scaling (DVS) with parallelism has shown to be an effective way of saving power while maintaining performance. However, the potency of DVS and parallelism in traditional, clocked synchronous systems is limited because of the strict …

Managing Many-Core Aging
Many-core scaling now faces a power wall. The gap between the number of cores that fit on a die and the number that can operate simultaneously under the power budget is rapidly increasing with technology scaling. In future designs, the majority of the cores will necessarily have to be dormant at …

Continuous voltage-frequency scaling (CVFS)
Voltage reduction is an effective technique for minimizing energy consumption but suffers from delay penalty. Conventional methodologies require rigorous voltage regulation and workload scheduling to meet timing constraints. In this work, we observe that static CMOS is robust under low supply …
