Evolvable Hardware for Extreme Environments: Hot or Cold
Temperature tolerant electronics and long life survivability are key capabilities required for future NASA/JPL missions. Current approaches to electronics for extreme environments focus on component level robustness and hardening. Compensation techniques, e.g., as offered by bias cancellation circuits, have also been employed. This paper presents a novel approach, based on evolvable hardware technology, which allows adaptive in situ circuit redesign/reconfiguration during the operation in the environment. This technology would complement material/device advancements and bring closer the success of missions in harsh environments. Additional information is contained in the original extended abstract.

Speed challenge: a case for hardware implementation in soft-computing
For over a decade, JPL has been actively involved in soft computing research on theory, architecture, applications, and electronics hardware. The driving force in all our research activities, in addition to the potential enabling technology promise, has been creation of a niche that imparts orders of magnitude speed advantage by implementation in parallel processing hardware with algorithms made especially suitable for hardware implementation. We review our work on neural networks, fuzzy logic, and evolvable hardware with selected application examples requiring real time response capabilities.
