Another take from us at Edge Impulse at explaining TinyML / Edge ML in our docs: https://docs.edgeimpulse.com/docs/concepts/what-is-embedded-...

We have built a platform to build ML models and deploy it to edge devices from cortex M3s to Nvidia Jetsons to your computer (we can even run in WASM!)

You can create an account and build a keyword spotting model from your phone and run in WASM directly https://edgeimpulse.com

Now another key thing that drives the Edge ML adoption is the arrival of the embedded accelerator ASICs / NPUs / e.g. that dramatically speed up computation with extremely low power - e.g. the Brainchip Akida neuromorphic co-processors [1]

Depending on the target device the runtime that Edge Impulse supports anything from conventional TFLite to NVIDIA TensorRT, Brainchip Akida, Renesas DRP-AI, MemryX, Texas Instruments TIDL (ONNX / TFLite), TensaiFlow, EON (Edge Impulse own runtime), etc.
