Abstract : The long term goal of this project is to develop and build an ultra-low power system-on-chip (SoC) that will increase the useful lifetime of animal tags for monitoring marine mammals to weeks or months and to integrate that chip into a new monitoring tag, called Nano-power Electronics MOdule (NEMO). The NEMO tag has the specific application goal of determining the response of deep diving whales to human generated acoustic events, although the tag and SoC will be programmable to support numerous other monitoring applications. The final goal is to provide fundamental research into the optimal tag partitioning between custom and off-the-shelf components, novel analog/digital co-design for acoustic event detection, and ultra-low power on-chip power and event management control to extend the lifetime of tags like NEMO as much as possible.
