Online AMS Frontend Reconfiguration for Sensor Network Applications

摘要

Sensor networks are increasingly important for many applications in environmental monitoring, manufacturing, defense and infrastructure monitoring. Many applications introduce variable performance requirements which demand online architecture reconfiguration, including the analog-digital frontends to sensors. This paper presents design automation methods for deciding the design points used for dynamic reconfiguration of analog-to-digital converters and DSP circuits. Experiments illustrate the methods for a sound-based tracking application.
