What Is Neuromorphic Computing?

Traditional silicon is getting a biological upgrade. Unlike conventional chips, brain-inspired hardware replicates the brain’s efficiency, blending neurons and synapses into silicon. This approach slashes power use while boosting speed—think 10 trillion operations per second.

Defining Brain-Inspired Hardware

These systems ditch rigid algorithms for *event-driven* processing. Intel’s Loihi chip, for example, packs 128 cores that learn via spike-timing-dependent plasticity (STDP). Samsung uses similar tech in vision sensors for factories, detecting defects in real time.

Key Components: Neurons and Synapses

At the core are two elements:

• Artificial neurons: Mimic biological “integrate-and-fire” mechanisms, activating only when inputs hit a threshold.
• Synaptic weights: Adjustable connections that strengthen or weaken signals, just like in neural networks.

By collocating memory and logic, these chips bypass the von Neumann bottleneck. The result? Devices that learn continuously—without draining batteries.

How Neuromorphic Computing Works

Forget constant power drains—these chips activate only when needed. Unlike traditional processors, brain-inspired designs use *event-driven* logic, mimicking how neurons fire in bursts. This slashes energy use while boosting speed.

Spiking Neural Networks (SNNs)

SNNs replicate biological brains by sending spikes (not continuous data). Only active neurons consume power, unlike GPUs that run full-tilt. IBM’s TrueNorth proves this—just 5% of its circuits fire during tasks.

“Loihi 2 delivers 1,000x better energy-delay product than CPUs, making it ideal for edge AI.”

Event-Driven Computation

Cameras like the DVS346 showcase this. They use 0.1W—less than a nightlight—by processing changes (like motion) instead of every frame. Response times drop to 8ms, beating standard 33ms systems.

Samsung’s Galaxy SmartTag leverages this for ultra-low-power tracking. MIT’s 2024 tactile sensor goes further, using *event-driven* signals to mimic human touch. The result? Devices that learn without wasting energy.
