CMSIS-MLEK Reference Application Package

This documentation explains the usage of the CMSIS-MLEK Reference Application Package for developing Machine Learning (ML) and Edge AI applications on Cortex-M processors with Ethos-U NPUs.

Target Audience

This user's guide assumes basic knowledge about Cortex-M software development and CMSIS-Toolbox workflows. It is written for embedded software developers who work with C/C++ compiler toolchains and develop machine learning applications for microcontroller devices with Cortex-M processors and Ethos-U NPUs.

Package Overview

The CMSIS-MLEK package provides ready-to-use templates and examples for machine learning applications. It includes three main template categories:

  • Audio Reference Applications - Keyword spotting and audio processing examples
  • Video Reference Applications - Object detection and video processing examples
  • Generic Reference Applications - General-purpose inference runner for custom ML models (available from version 1.0+)

Manual Chapters

Available Templates

The package includes the following example templates:

Template Description Key Features
Audio/KWS Keyword spotting application Real-time audio processing, wake word detection
Audio/User Algorithm Customizable audio processing template Template for implementing custom audio ML algorithms
Video/Object Detection Object detection using camera input Real-time object detection, bounding box visualization
Video/User Algorithm Customizable video processing template Template for implementing custom video ML algorithms
Generic/Inference Runner General-purpose ML inference Support for custom TensorFlow Lite models

Supported Platforms

The templates support multiple Arm Cortex-M platforms:

  • Corstone-300 (Cortex-M55 + Ethos-U55/U65)
  • Corstone-310 (Cortex-M85 + Ethos-U55/U65)
  • Corstone-315 (Cortex-M85 + Ethos-U65)
  • Corstone-320 (Cortex-M85 + Ethos-U85)

Each template can be built for both Arm Virtual Hardware (AVH) simulation and physical evaluation boards.
