Ambiq Launches heliaCORE for Real-World Edge AI Deployment
Production-grade AI kernel foundation validated across 40+ AI models and ~12x more operator instances than MLPerf Tiny on Apollo SoCs.

AUSTIN, Texas, June 23, 2026 — Ambiq Micro, Inc. (“Ambiq®”), a technology leader in ultra-low-power semiconductor solutions for edge AI, today announced heliaCORE™, the foundational software layer powering its HELIA™ Edge AI ecosystem. Built specifically for Apollo SoCs, heliaCORE provides optimized AI kernels, broad operator acceleration, and production-scale validation to help developers bring AI-enabled products to market faster on resource-constrained edge devices.

Designed for production edge AI workloads, heliaCORE accelerates not only core neural network kernels but also critical inference operations—including activations, padding, reductions, reshapes, and data movement—to improve real-world performance and efficiency while reducing the complexity of bringing AI-enabled products to market. Built on the Arm® CMSIS-NN ecosystem, heliaCORE preserves compatibility with industry-standard embedded AI development workflows.

“The future of AI will be defined by intelligent devices operating at the edge, but moving AI from experimentation to real-world deployment remains one of the industry’s biggest challenges,” said Dr. Adam Page, Head of AI at Ambiq. “heliaCORE is a foundational building block of the HELIA ecosystem, providing the software infrastructure developers need to deploy edge AI faster and with greater confidence.”
