Description

X-CUBE-AI is an STM32Cube Expansion Package designed to evaluate, optimize, and compile edge AI models for STM32 microcontrollers and the Neural-ART Accelerator. When optimizing NN models for the Neural-ART Accelerator NPU, the tool generates the microcode that maps AI operations to the NPU when possible, falling back to CPU when necessary. This scheduling is performed at the operator level to maximize AI hardware acceleration. X-CUBE-AI is part of the STM32Cube.AI ecosystem and extends STM32CubeMX capabilities by automatically converting pretrained artificial intelligence algorithms into C code. It also integrates a generated optimized library into the user's project.

The easiest way to use X-CUBE-AI is to download it inside the STM32CubeMX tool (version 5.4.0 or newer) as described in the user manual "Getting started with X-CUBE-AI Expansion Package for artificial intelligence (AI)" (UM2526).

The X-CUBE-AI Expansion Package also offers several means to validate artificial intelligence algorithms both on a desktop PC and an STM32. With X-CUBE-AI, it is also possible to measure performance on STM32 devices without any user-specific handmade C code.

ST Edge AI Suite

X-CUBE-AI is part of STMicroelectronics ST Edge AI Suite, which is an integrated collection of software tools designed to facilitate the development and deployment of embedded AI applications. This comprehensive suite supports both optimization and deployment of machine learning algorithms and neural network models, from data collection to the final deployment on hardware, streamlining the workflow for professionals across various disciplines.

The ST Edge AI Suite supports various STMicroelectronics products: STM32 microcontrollers and microprocessors, Neural-ART Accelerator, Stellar microcontrollers, and smart sensors.

The ST Edge AI Suite represents a strategic move to democratize edge AI technology, making it a pivotal resource for developers looking to harness the power of AI in embedded systems efficiently and effectively.
