A Brain-Inspired Approach to Rapid and Energy Efficient Information Processing: AI on the Fly – TAMU X-grants
Senior Personnel: S. Banerjee (Lead), P. Shamberger (Co-Lead), S. Williams (Co-Lead), R. Arroyave, P. Balbuena, J. Batteas, L. Fang, B. Mallick, S. Palermo, M. Pharr, X. Qian, K. Xie


Processing, storing, and transmitting information already accounts for ca. 10% of global energy use; estimates suggest that by 2040, the demand for computation will be 10× higher than the projected global energy supply. The human brain serves as a powerful exemplar of processing complex information with minimal energy dissipation.

Unlike binary von Neumann architectures, where computing operations constantly fetch data from a central processor, neural elements use distributed, dynamically evolving, and interacting weights (memories) stored across a dense, highly interconnected network.
