Dynamic Voltage Scaling in Pda Devices

Dynamic Voltage Scaling in Mobile Devices

Energy efficiency is an important property of mobile and pervasive computing devices. Dynamic voltage scaling (DVS) offers a technique to potentially achieve this property by reducing the energy consumption of the microprocessor. There has been much research conducted in the area of DVS algorithms. However, many of these algorithms have only been tested in simulation environments. In this paper...

Power-Saving Scheduling for Weakly Dynamic Voltage Scaling Devices

We study the problem of non-preemptive scheduling to minimize energy consumption for devices that allow dynamic voltage scaling. Specifically, consider a device that can process jobs in a non-preemptive manner. The input consists of (i) the set R of available speeds of the device, (ii) a set J of jobs, and (iii) a precedence constraint Π among J . Each job j in J , defined by its arrival time a...

Control-theoretic dynamic voltage scaling for embedded controllers

For microprocessors used in real-time embedded systems, minimizing power consumption is difficult due to the timing constraints. Dynamic voltage scaling (DVS) has been incorporated into modern microprocessors as a promising technique for exploring the trade-off between energy consumption and system performance. However, it remains a challenge to realize the potential of DVS in unpredictable env...
