STAR: An Efficient Softmax Engine for Attention Model with RRAM Crossbar
Kavli Affiliate: Jing Wang | First 5 Authors: Yifeng Zhai, Bing Li, Bonan Yan, Jing Wang, | Summary: RRAM crossbars have been studied to construct in-memory accelerators for neural network applications due to their in-situ computing capability. However, prior RRAM-based accelerators show efficiency degradation when executing the popular attention models. We observed that the frequent […]

Hierarchical phased-array antennas coupled to Al KIDs: a scalable architecture for multi-band mm/submm focal planes
Kavli Affiliate: Sunil R. Golwala | First 5 Authors: Jean-Marc Martin, Junhan Kim, Fabien Defrance, Shibo Shu, Andrew D. Beyer | Summary: We present the optical characterization of two-scale hierarchical phased-array antenna kinetic inductance detectors (KIDs) for millimeter/submillimeter wavelengths. Our KIDs have a lumped-element architecture with parallel plate capacitors and aluminum inductors. The incoming light […]

Spike transmission failures in axons from mouse cortical pyramidal neurons in vivo
Kavli Affiliate: Rafael Yuste | Authors: Netanel Ofer, Victor Hugo Cornejo and Rafael Yuste | Summary: Abstract The propagation of action potentials along axons is traditionally considered to be reliable, as a consequence of the high safety factor of action potential propagation. However, numerical simulations have suggested that, at high frequencies, spikes could fail to […]
