Energy-aware task scheduling with task synchronization for embedded real-time systems

Real-Time Task Scheduling for Energy-Aware Embedded Systems

We present a new approach for scheduling workloads containing periodic tasks in real-time systems. The proposed approach minimizes the total energy consumed by the task set and guarantees that the deadline for every periodic task is met. As embedded software becomes a larger component of system-on-a-chip design, energy management using the operating system becomes increasingly important. We pre...

Energy Aware EDF Scheduling with Task Synchronization for Embedded Real Time Systems

Slowdown factors determine the extent of slowdown a computing system can experience based on functional and performance requirements. Dynamic Voltage Scaling (DVS) of a processor based on slowdown factors can lead to considerable energy savings. For the Earliest Deadline First (EDF) scheduling, the problem of DVS in the presence of task synchronization has not yet been addressed. We compute slo...

Task Scheduling in Energy Harvesting Real-time Embedded Systems

Harvesting energy from the environment is very desirable for many emerging applications that use embedded devices. Energy harvesting also known as energy scavenging enables us to guarantee quasi-perpetual system operation for wireless sensors, medical implants, etc. without requiring human intervention which is normally necessary for recharging batteries in classical battery-operated systems. N...

Power-aware scheduling with effective task migration for real-time multicore embedded systems

Requirements for Static Task Scheduling in Real Time Embedded Systems

Static task scheduling is an important step in embedded system design. In this paper, we have studied a recently proposed representation model, called Multi Thread Graph and a given static scheduling heuristic based on this MTG. Applying the heuristic to the software part of a GPS receiver, we have successfully scheduled the tasks under the required timing constraints. The experiment shows that...
