RAMP: accelerating wireless sensor hardware design with a reconfigurable analog/mixed-signal platform

Published: 13 April 2015 Publication History

Abstract

To meet the demanding requirements in the growing area of wireless sensing applications, some sensing platforms have included low-power application-specific hardware to process the sensor data for compression and pre-classification of the relevant information. While this additional hardware can reduce the overall power consumption of the system, a unique hardware solution is required for each application. To diminish this burden, we will demonstrate a reconfigurable analog/mixed-signal sensing platform. At the hardware-level, this platform consists of a reconfigurable integrated circuit containing many commonly used circuit components that can be connected in any configuration to perform sensor interfacing and ultra-low-power signal processing. At the software level, this platform provides a framework for abstracting the underlying hardware. We will demonstrate how our platform allows a developer to create applications ranging from standard sensor interfacing techniques to more complicated intelligent pre-processing and wake-up detection, without the necessity of circuit-level expertise.
