varPower
varPower is a framework and set of techniques for managing electrical power in electronic systems by exploiting variability in workload and environment to optimize energy efficiency and performance. It integrates hardware power states with software control to adjust power delivery and consumption in response to observed or predicted demand.
Origin and scope: The term varPower has appeared in academic papers and industry discussions since the early
Technical description: Implementations combine hardware mechanisms—including voltage regulator modules and power management ICs—with software runtimes that
Applications and impact: VarPower has been explored in mobile devices, embedded systems, and data centers to
Limitations and criticism: Heavy reliance on accurate workload modeling can lead to missed optimization opportunities or
