Drop-in LiteRT for Micro with Ambiq-tuned kernels.
heliaRT is Ambiq's optimized LiteRT for Micro runtime for Apollo platforms, compatible with TensorFlow Lite for Microcontrollers / TFLM. It adds heliaCORE, a set of Ambiq-tuned kernel implementations, on top of the standard LiteRT for Micro API so you get faster inference without changing your application code.
Choose an integration path, then select source builds or a compatible prebuilt archive. Match the runtime headers, compiler ABI, architecture and float settings to your application.
| Path | Guide |
|---|---|
| Zephyr / west | Zephyr integration |
| neuralSPOT-X | NSX integration |
| Make / CMake source builds | Build from source |
| Prebuilt static libraries | Use a release archive |
| CMSIS-Pack | Create and consume a source pack |
- Getting started: integration choices and first inference.
- User guide: backends, SPEED/SIZE profiles, build flags, memory, profiling and troubleshooting.
- Operators and data types: searchable adapter coverage and input-type constraints.
- API reference: runtime contracts and source declarations.
- Maintenance: repository structure, testing, upstream sync and releases.
The documentation source and authoring instructions live in astro-site. Edit those pages instead of duplicating integration instructions in the repository readme. The site records the source commit used for each build.
