heliaAOT Ultra-Low Power Edge AI Compiler

From Trained Models to Optimized Silicon

KV mobile Nemo 1

heliaAOT™ is an ahead-of-time AI compiler that converts LiteRT models into optimized, standalone C inference modules for Ambiq SoCs. It reduces processing time, energy, and memory for on-device inference, runs FP16 and FP32 models without integer quantization, and supports custom operators and streaming layers for always-on products in wearables, healthcare, smart home, and industrial sensing.

Key Features of heliaAOT for Edge AI

01

Faster, More Efficient Inference

Up to 76% lower latency and up to 72% lower energy per inference than LiteRT Micro in Apollo510 benchmarks*

02

Smaller Firmware Footprint

Median firmware images are 29% to 56% smaller than LiteRT Micro, with automatic tensor memory planning that removes over-allocation and unused code

03

Full Precision, Broader Model Support

Run FP16 and FP32 models without integer quantization, with 65 operators, custom operators, and streaming LSTM, GRU, and SVDF layers for always-on workloads

04

Seamless Integration Across Apollo

Retarget supported models across 15 Apollo SoCs with a one-line configuration change, and integrate as a Zephyr RTOS module or neuralSPOT plug-in

Why AI Model Optimization Matters

As AI models become larger and more sophisticated, deploying them on battery-powered edge devices becomes increasingly challenging. AI model optimization reduces memory requirements and computational overhead, enabling advanced AI workloads to run efficiently within power and resource constraints. This allows developers to deliver more sophisticated on-device intelligence while preserving battery life and minimizing cloud dependency.
