N1
First Generation
N1
The foundation.
128 cores. One mesh.
The Catalyst N1 is a 128-core spiking neuromorphic processor with full parity to Intel's first-generation Loihi chip. Each core contains 1,024 neurons, 131K synapses, and a programmable learning engine.
Dendritic trees
Four compartments per neuron for spatial computation.
Graded spikes
Eight-bit payload per spike for analog-like signalling.
On-chip learning
Programmable plasticity rules. The chip learns as it runs.
