Voltage-Clock-Scaling Adaptive Scheduling Techniques for Low Power in Hard Real-Time Systems
—Many embedded systems operate under severe power and energy constraints. Voltage clock scaling is one mechanism by which energy consumption may be reduced: It is based on the fa...

Finding the Worst Voltage Violation in Multi-Domain Clock Gated Power Network
This paper proposes an efficient method to find the worst case of voltage violation by multi-domain clock gating in an on-chip power network. We first present a voltage response i...
