Embedded systems have limited resources, such as computation capabilities and battery life. The Dynamic Voltage and Frequency Scaling (DVFS) technique is used to save energy by running the processor of the embedded system at low voltage and frequency levels. However, this prolongs the execution time, which may cause potential deadline misses for real-time tasks. In this paper, we propose a general-purpose...
Performance boosting of modern computing systems is constrained by the chip/circuit power dissipation. Dynamic voltage scaling (DVS) has been applied for reducing the energy consumption by dynamically changing the supply voltage. One can optimistically apply greedy online DVS scheduling algorithms by considering only the events that have arrived in the system. However, this might require a speed that...
Dynamic power management has become essential for battery-driven embedded systems. This paper explores how to efficiently and effectively reduce the energy consumption of a device (system) for serving multiple event streams. Considering two different preemptive scheduling, i.e., earliest deadline first and fixed priority, we propose new method to adaptively control the power mode of the device according...
Thermal constraints have limited the performance improvement of modern computing systems in recent years. As a system could fail if the peak temperature exceeds its thermal constraint, overheating should be avoided while designing a system. Moreover, higher temperature also leads to higher leakage power consumption. This paper explores dynamic thermal management to minimize the energy consumption...
The pursuit of energy efficiency is becoming more and more important in hardware and software designs. This research explores energy-efficient scheduling for a periodic real-time task with uncertain execution time in dynamic voltage scaling (DVS) systems with non-negligible leakage/static power consumption. Distinct from the assumption of non-reducible static power consumption in the literature, this...
Many computing systems have adopted the dynamic voltage scaling (DVS) technique to reduce energy consumption by slowing down operation speed. However, The longer a job executes, the more energy in leakage current the processor consumes for the job. To reduce the power/energy consumption from the leakage current, a processor can enter the dormant mode. Existing research results for leakage-aware DVS...
