An Integrated Tool Tailored for Engineers, Enabling Fast AI Model Deployment to MCU

Hsinchu, Taiwan – May 27, 2025 – As AI technology rapidly integrates into various embedded systems, how to efficiently deploy trained AI models onto resource-constrained microcontrollers has become a significant challenge for engineers. To help developers quickly implement AI solutions, Nuvoton Technology has launched the NuML Toolkit. This tool integrates model conversion, project generation, deployment, and debugging processes. It is specially optimized for the NuMicro® M55M1 microcontroller platform and has received widespread acclaim from users.

The NuML Toolkit offers comprehensive process support, including:

• Model Conversion and Deployment
  Automatically converts Full-INT8 quantized models into .cpp files and integrates them into Arm® Keil® project templates.
• Toolchain Support
  Supports both Keil (μVision®5 / Arm Compiler 6) and GNU Compiler Collection (make / gcc).
• High Integration
  Automatically opens the Keil project and performs flashing after deployment, enabling immediate inference result viewing.
• Flexible Expandability
  Developers can adjust Tensor Arena, input / output handling, and other parameters based on model needs.
• Cross-Platform Support
  Uses Miniforge to set up the environment, simplifying dependency management and quickly introducing toolchains.

Three Key Advantages of NuML Toolkit:

1. Fast and Simple Model Conversion
   Through command-line operations, users can generate corresponding AI MCU projects with just a few parameters, without writing complex code manually.

2. Integrated Workflow
   From model quantization → project building → microcontroller flashing → result verification, the toolkit provides a fully integrated workflow that is easy to use for both beginners and experienced engineers.

3. High Flexibility and Maintainability
   The generated Keil project contains a modular code architecture (such as Application, Model, Device), making it easy for customers to modify and maintain according to actual needs. Model management is flexible—large models can be configured to use SD cards or HyperRAM™, with memory usage strategies automatically adjusted based on resource allocation.

The NuML Toolkit is a highly efficient tool designed for AI applications on microcontrollers, helping customers complete AI model deployment and validation in the shortest time. It has already been widely applied in applications such as smart desk lamps, posture recognition, sound recognition, image detection, and other scenarios, becoming one of the preferred tools in the Nuvoton NuMicro® AI MCU developer community.
