Music went digital in the 1980s and has now gone portable. Today, it can be played on miniature devices that allow unhindered access to any tune, at any time, anywhere. The slim formats of these products only allow for a tiny, compact battery, so that exceptionally low-power consumption is needed to give users freedom from their battery chargers.

The specialized architecture of the AudioDE processor has been created to meet this need, delivering unrivaled, low-power performance. This article examines various aspects of the AudioDE processor in detail: the core architecture, subsystem autonomy, and system-level software integration. Third-party software support for AudioDE is also discussed, as are products in which AudioDE is typically used, including portable media players, music cell phones, wireless headsets and digital radio.
