摘要

This paper proposes a neuromorphic processing system and its classifier design for always-on wearable electrocardiogram (ECG) classification. The ECG signal is captured by level crossing (LC) sampling yielding single-bit temporal coding that can be natively fed into a spiking neural network (SNN) in an event-driven manner. Such an architecture simplifies the quantization of analog-to-digital conve...
