Modern autonomous underwater vehicles (AUVs) have advanced sensingcapabilities including sonar, cameras, acoustic communication, and diversebio-sensors. Instead of just sensing its environment and storing the data forpost-Mission inspection, an AUV could use the collected information to gain anunderstanding of its environment, and based on this understanding autonomouslyadapt its behavior to enhance the overall effectiveness of its mission. Manysuch tasks are highly computation intensive. This paper presents the results ofa case study that illustrates the effectiveness of an energy-aware, many-corecomputing architecture to perform on-board path planning within abatteryoperated AUV. A previously published path planning algorithm was portedonto the SCC, an experimental 48 core single-chip system developed by Intel.The performance, power, and energy consumption of the application were measuredfor different numbers of cores and other system parameters. This case studyshows that computation intensive tasks can be executed within an AUV thatrelies mainly on battery power. Future plans include the deployment and testingof an SCC system within a Teledyne Webb Research Slocum glider.
