Key Features of heliaAOT for Edge AI

Zero Guesswork in Memory Allocation

Automatic tensor memory planning eliminates over-allocation and strips away unused code for lean, efficient deployment.

Up to 10x Smaller Code Size

Dramatically reduces flash footprint on Apollo SoCs compared to standard TensorFlow Lite for Microcontrollers.

Deep Optimization & Customization

Fine-tune inference pipelines at the operator, subgraph, or full graph level with advanced techniques like layer fusion, tensor reordering, and intelligent memory placement.

Seamless Integration

Easily integrates as a Zephyr RTOS module or as a plug-in to Ambiq’s neuralSPOT AI Development Kit (ADK) for streamlined workflow.

Uncompromising Performance

Get heliaRT-level inference speed in a tiny package—heliaAOT slashes memory footprint by up to 2.6× on MLPerf Tiny models.
