We propose a novel temporal-digital architecture that encodes ANN weights as delays and activations as signal arrival times, enabling full ANN execution with temporal reuse, noise-tolerant summation, and hybrid memory, achieving up to 11× energy and 4× latency improvements over SNNs, and 3.5× energy savings over 8-bit digital systolic arrays.
Event-Based Vision at the Edge
Neuromorphic event‐based vision sensors are poised to dramatically improve the latency, robustness and power in applications ranging from smart sensing to autonomous driving and assistive technologies for people who are blind.
Soon these sensors may power low vision aids and retinal implants, where the visual scene has to be processed quickly and efficiently before it is displayed. However, novel methods are needed to process the unconventional output of these sensors in order to unlock their potential.

A GPU-accelerated cortical neural network model for visually guided robot navigation
We present a cortical neural network model for visually guided navigation that has been embodied on a physical robot exploring a real-world environment. The model includes a rate based motion energy model for area V1, and a spiking neural network model for cortical area MT. The model generates a cortical representation of optic flow, determines the …
