Probabilistic arithmetic and energy efficient embedded signal processing [PDF]

open access: yesProceedings of the 2006 international conference on Compilers, architecture and synthesis for embedded systems, 2006
Probabilistic arithmetic, where the ith output bit of addition and multiplication is correct with a probability pi , is shown to be a vehicle for realizing extremely energy-efficient, embedded computing. Specifically, probabilistic adders and multipliers, realized using elements such as gates that are in turn probabilistic, are shown to form a natural ...

An Energy Scalable Functional Unit for Sensor Signal Processing [PDF]

open access: yes2007 IEEE International Conference on Acoustics, Speech and Signal Processing - ICASSP '07, 2007
Low power signal processing functionality is required for wireless sensor network nodes due to their limited battery life. Previously, we have proposed a reconfigurable array of DSP acceleration functional units for such a sensor node. The array maximizes operating life by matching system power consumption to available energy through power scalable ...

Energy-efficient on-node signal processing for vibration monitoring [PDF]

open access: yes2014 IEEE Ninth International Conference on Intelligent Sensors, Sensor Networks and Information Processing (ISSNIP), 2014
In recent years, the use of wireless sensor networks for vibration monitoring is emphasized, because of its capability to continuously monitor at hard-to-reach locations of complex machines. Low power consumption is one of the main requirements for the sensor nodes in continuous and long-term vibration monitoring.
