The Topological Acoustic Synapse is a neuromorphic hardware device that uses acoustic waves to perform high-dimensional neuromorphic computing. The device encodes information in a multivariate state space and uses nonlinear acoustic wave interactions to reproduce synapse-like behavior for computation. By shifting key functions from purely electronic signaling to acoustic-wave interactions, the technology is intended to provide parallel processing, rapid convergence with fewer parameters, and ultra-low power operation. It is also designed to reduce wiring complexity and hardware footprint while supporting scalable systems with high computational density. In practical terms, this offers a hardware approach aimed at handling complex AI-style workloads more efficiently by representing and processing richer sets of information states directly through device behavior, rather than relying on larger, more power-hungry architectures to reach similar outcomes. Background: Many neuromorphic hardware approaches, including memristors, transistor-based designs, and spintronic oscillators, face recurring constraints tied to bandwidth, energy use, wiring complexity, footprint, and reliability. These constraints can limit performance and make it difficult to scale systems as model sizes and real-time processing demands grow. The Topological Acoustic Synapse was developed to address these issues by using acoustic-wave interactions as the core computing mechanism, offering a different path to neuromorphic processing that targets lower power use, fewer wiring demands, and improved scalability. Because the technology encodes information in a high-dimensional state space and uses nonlinear wave interactions to carry out synapse-like functions, it is intended to support dense, parallel computation in hardware while reducing several system-level burdens that affect many traditional neuromorphic devices.
