Design of an Energy-Aware System-in-Package for Playing MP3 in Wearable Computing Devices

More and more mobile devices are being produced to meet consumers' increasing demand for instant entertainment, information, and communications anywhere at any time. Mobile and wearable devices are designed to have the longest possible active-on and standby times with the lowest possible weight and smallest size.

This paper discusses how the size and weight of these devices can be significantly decreased by using energy-efficient design methodologies. The design of energy-aware gadgets includes not only hardware, but also software techniques. In this paper, a single-chip multimedia system is reviewed for use within wearable devices, and results from the study of an austriamicrosystems MP3 player are presented.
