ETHEREAL is presented, the first EV-GNN accelerator that scales to 640-times-480 resolutions, thanks to a neighbor-parallel spline convolution engine and a 2D/3D-split memory hierarchy with a novel region-of-interest spatiotemporal caching mechanism.

ETHEREAL achieves sub-30 μs latency for high-resolution vision tasks, setting a new standard for event-driven processing at the edge.
