I came across an interesting article which outlined potential future research and advances in computing power usage. If indeed the claims made in this article are true, this could drastically reshape battery life in many applications. Just don’t expect me to drive a car with this technology anytime soon.
Several other possibilities exist, which I’ll just list briefly:
– Use multiple chips to gain reasonable confidence of the answer (1 or 0)
– Use one of these power saving chips for most computations, and a normal chip for important decisions
