Abstract :
More and more mobile devices are being produced to fulfill increasing consumer demand for immediate entertainment, instant information, and communications anywhere at any time. Mobile and wearable devices are designed to have the longest possible active-on and standby times and lowest weight and smallest size. Size and weight can be significantly decreased by using energy-efficient design methodologies. System-on-chip (SOC) and system-in-package (SIP) emerged as key technologies for developing wearable devices. 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. The presented results are derived from studying the behavior of an MP3 player produced by austriamicrosystems.
