DBNN enables accurate, low-power neural spike sorting for brain-computer interfaces

Researchers have developed a Deep Binarized Neural Network (DBNN) for on-node spike sorting in implantable brain-computer interfaces. This DBNN system, featuring two binarized hidden layers, enables multiplier-free inference using sign-controlled accumulation and bit-wise logic. The proposed classifier achieves a median accuracy of 98.7% on synthetic and in-vivo datasets, with an FPGA prototype demonstrating low latency and hardware cost. ASIC feasibility studies indicate a small silicon area and extremely low operating power, making it suitable for low-power, implantable neural interfaces. AI
