Embedded AI Integration with MATLAB and Simulink
Key Characteristics
When we are talking about Embedded AI, there are three key features that you need to remember:- Integration with Hardware - AI algorithms are integrated into the device hardware, often requiring optimization to run efficiently on limited resources.
- Dedicated Functions - The AI capabilities are tailored to specific applications, such as voice recognition in smart speakers or image processing in cameras.
- Limited Resources - Embedded systems typically have constraints on processing power, memory, and energy consumption.
Embedded AI vs Edge AI vs TinyML
The terms Embedded AI, Edge AI, and TinyML refer to closely related but distinct concepts within the field of artificial intelligence, each with its unique focus and application domains. All three approaches have a component of real-time or near-real-time processing. The key attribute of Embedded AI is a resource-constrained target, such as an MCU (microcontroller unit), that cannot use libraries. Thus, Embedded AI requires embedded code (C/C++ or HDL). Edge AI is Embedded AI plus running AI models on industrial computers. Industrial computers have much more resources than embedded systems. TinyML is a sub-area of Embedded AI, which brings AI to the smallest MCUs and sensors, and thus operates under the most stringent limitations.

You can use MATLAB and Simulink to design, simulate, test, verify, and deploy Embedded AI algorithms that enhance the performance and functionality of complex engineering systems. MATLAB and Simulink provide a complete and versatile set of tools for designing complex AI-empowered embedded systems for applications such as enhancing a quality inspection robot with deep learning or developing a control system that uses virtual sensors for temperature estimation.

Some of the key benefits of using MATLAB and Simulink tools for Embedded AI are:- Simulation and Testing of AI-driven systems in Simulink. Trained machine learning models can be easily integrated into Simulink systems using provided Simulink blocks. You can evaluate the model performance within the system, and perform processor-in-the-loop (PIL) or hardware-in-the-loop (HIL) testing.

- Integration between MATLAB and Python for deep learning. You can import pretrained deep learning models from PyTorch®, TensorFlow™, and ONNX™ into MATLAB. You can also export deep neural networks from MATLAB to TensorFlow and ONNX. To learn more, check out Convert Deep Learning Models between PyTorch, TensorFlow, and MATLAB.
- Deployment to Resource-Constrained Targets. You can generate plain C/C++ source code (with no dependency on a runtime or interpreter) for CPUs and microcontrollers, CUDA code for NVIDIA® GPUs, and Verilog and VHDL® code for AMD & Intel® FPGAs and SoCs. You can also compress models to reduce their computational costs by performing pruning, projection or quantization.
- Verification and Validation for AI. You can verify and validate AI models, especially in safety-critical industries such as automotive, aerospace, and medical devices (to learn more, see blog post series: Verification and Validation for AI). You can apply explainable AI techniques for machine learning and deep learning models, and verify the robustness of deep neural networks with Deep Learning Toolbox Verification Library.
