Implementation of Dynamic Voltage and Frequency Scaling on Portable Audio Player

Current portable computing device demands not only higher performance but also lower power consumption. For the same reason, this research aims to build a framework that enables a rapid design of energy-efficient embedded systems. Specifically, this research is focused on dynamic voltage scaling algorithm, which has been found effective in saving power consumption. We develop a method of scaling voltage and frequency dynamically on the latest embedded processor, jointly designed by Analog Devices and Intel. The rationale behind this method is to avoid processor being idle in high operating frequency and voltage. Instead, processor can save power by running task at lower frequency and voltage, and completing it just before the real-time deadline. Furthermore, our method can also be implemented in other embedded processors with voltage-frequency scaling feature.
