Run-Time Software Multithreading

Embedded systems running under dynamic conditions often encounter the arrivals of new TF at run-time. Conventional run-time scheduling approaches are mostly focused on the topic of how to schedule both existing TF and new TF together such that all (hard and/or soft) real-time constraints are met. However, today’s portable embedded systems do not only require a schedule that can fulfill the timing constraints, they also need a run-time scheduler that produces energy-efficient schedules and causes very little overheads in order to meet the constraints of energy dissipation. Chapter 6 has considered the needs of energy-efficient run-time scheduling and presented the basic run-time scheduling technique.
