GenesisAeon Entropy Atlas Package 26 — Neuromorphic SNN Hardware Bridge (Intel Loihi 2)

spiking-aeon — Package 26

Neuromorphic SNN Hardware Bridge (Intel Loihi 2) — GenesisAeon Entropy Atlas Package 26

Bridges the GenesisAeon CREP weight system to physical Spiking Neural Network hardware (Intel Loihi 2). CREP tensor components C, R, E, P are translated into LIF neuron parameters. Software simulation runs without hardware via the pure-Python Brian2-compatible backend.

Calibrated against NeuEdge (arXiv:2602.02439, 2026): 847 GOp/s/W · 2.3 ms latency · 89% core utilisation · 312x energy improvement over GPU.

SNN UTAC Model

Parameter	Value	Meaning
K	1000 Hz	Max sustainable Loihi 2 firing rate
H*	320 Hz	Critical firing rate for task performance
eta	0.32	H*/K — SNN operating setpoint
Gamma	~0.150	arctanh(0.32) / 2.2 — SNN hardware criticality index

CREP -> LIF Parameter Mapping

CREP	LIF Parameter	High value effect
C	tau_m (membrane time constant)	Longer integration window
R	I_noise amplitude	Optimal stochastic resonance
E	Synaptic weight W	Stronger collective coupling
P	tau_ref (refractory period)	Richer temporal coding

Usage

from spiking_aeon.system import SpikingAeon

sim = SpikingAeon(n_neurons=1000, seed=42)

# Software simulation (no hardware required)
result = sim.run_cycle(duration_ms=1000.0)
print(f"Mean firing rate: {result['mean_rate_hz']:.1f} Hz")

# CREP criticality tensor
crep = sim.get_crep_state()
print(f"Gamma = {crep['Gamma']:.4f}  (reference: {crep['Gamma_ref']})")

# UTAC state
utac = sim.get_utac_state()
print(f"H = {utac['H']:.4f}, below threshold: {utac['below_threshold']}")

# Zenodo record
record = sim.to_zenodo_record()

Stochastic Resonance

sr = sim.optimise_stochastic_resonance(n_steps=20)
print(f"Optimal noise D_res = {sr['D_res']:.3f}  (min CV = {sr['min_CV']:.3f})")

Deploy to Loihi 2

# Requires INRC access + pip install lava-nc

Role in the GenesisAeon Ecosystem

spiking-aeon is Package 26 of the GenesisAeon Entropy Atlas, in the neuromorphic hardware domain. It bridges the GenesisAeon CREP criticality framework to physical Spiking Neural Network hardware (Intel Loihi 2), positioning SNN firing-rate criticality (Γ ≈ 0.150) on the ecosystem's broader CREP Criticality Spectrum alongside other domains such as qubit decoherence, apoptosis, and self-organized criticality.
