arXiv:2607.05590v1 Announce Type: cross Abstract: Implantable brain-computer interfaces require on-node spike sorting to reduce telemetry bandwidth and power while maintaining reliable neural decoding. This paper presents a hardware-oriented deep binarized neural network (DBNN) spike-sorting system with two binarized hidden layers with 256 neurons and a fixed-point output layer to enable multiplier-free inference dominated by sign-controlled accumulation and bit-wise logic. The proposed classifier operates on compact 16-sample spike waveforms to reduce the implementation cost (16-256-256-3) an
Advances in neural networks and binarization techniques are converging with the increasing demand for efficient on-node processing in brain-computer interfaces, pushing the technical frontier for real-time spike sorting.
This research is critical for scaling brain-computer interfaces by directly addressing the power and bandwidth limitations that currently constrain widespread adoption and long-term implantability.
The development of hardware-optimized deep binarized neural networks for spike classification significantly lowers the compute burden for real-time neural decoding, enabling more practical and smaller implantable devices.
