Spike Encoding Efficiency Benchmark

A standardized measurement of how efficiently a neuromorphic system converts real-world signals into spike trains — the single most important bottleneck in practical neuromorphic computing.

What It Is

Spike encoding is where the analog world meets the digital spike domain. How a system encodes sensory input into spikes determines its information density, latency, and energy cost for all downstream processing. Most neuromorphic benchmarks measure compute performance after encoding. We measure encoding itself.

Our benchmark protocol tests encoding schemes against standardized input streams (visual, auditory, tactile, and time-series data) and reports efficiency in bits-per-spike and joules-per-bit.

What You Get

Encoding efficiency scores — bits-per-spike across four input modalities
Energy cost profile — joules per encoded bit, compared to conventional ADC baselines
Latency measurement — encoding delay from input to first spike under varying load
Information loss analysis — what the encoding scheme discards, and whether it matters for target applications
Scheme comparison — rate coding vs. temporal coding vs. population coding on your specific workload
Optimization recommendations — parameter tuning and architectural changes to improve encoding efficiency
