Composable Power Management With Energy and Power Budgets Per Application

Executive Summary

Embedded Multi-Processor Systems-on-Chip (MPSoCs) commonly run multiple applications at once. These applications may have different time criticalities, i.e. non real-time, soft real-time, and firm or hard real-time. Application-level composability is used to provide each application with its own virtual platform, such that each application may be developed, verified, and executed independently, given its virtual platform specification. Composability of functional and temporal properties has been demonstrated in previous work. In this paper, the authors extend composability to include power management, where each application can manage its energy usage independently.
