Ambiq Micro, a microcontroller manufacturer, has created its own AI-focused software development kit (SDK) to enable efficient inference using ultra-low power sub-threshold and near-threshold technologies.
The SDK includes an open-source model zoo with health and speech detection/processing examples, including voice activity detection, keyword detection and speech to intent.
The new SDK is designed for all fourth-generation Apollo chips but the Apollo4 Plus SoC is particularly suited to always-on AI applications due to its low power consumption. The combination of Ambiq's Neural Spot AI SDK with its ultra-low power sub-threshold and near-threshold technologies is expected to suit IoT devices, especially wearables.
