Safety-Critical Meets Web-Native: Wasm Revolutionizes Embedded Systems
summary
Wasm runs on constrained devices using the WebAssembly Micro Runtime (WAMR) and AOT pipelines, achieving runtimes as small as 50K (research pushes toward ~5K) and appearing in ~1.5 million deployed devices (streaming and consumer OEMs). It delivers software isolation on chips without an MMU, supports polyglot components without system-wide GC, and enables mixed‑criticality setups (real‑time C code plus sandboxed modules). A fully safety‑certified Wasm runtime is not yet available, but OSS projects and an embedded SIG are actively driving standards and tooling.
