The evolution from IoT to AIoT

In the history of embedded systems, we have moved from the discrete digital logic of the 1960s to the hyper-connected IoT era of the late 2000s, enabled by the ability to connect even small devices reliably to the cloud. This connectivity unlocked entirely new classes of applications, but it also introduced a strong dependency on continuous communication.

Today, we are seeing the next evolution with AIoT (Artificial Intelligence of Things). Advances in hardware and software now make it possible to embed intelligence directly at the edge, allowing devices to operate more autonomously and remain functional even when cloud connectivity is limited or temporarily unavailable. In practice, this leads to hybrid architectures where local intelligence complements the cloud rather than replaces it.

As expectations for ‘smart’ products continue to rise, addressing this paradox within fixed time and budget constraints requires a shift in design philosophy. This shift involves combining the right state-of-the-art technologies to increase engineering efficiency and reduce development complexity.

The rise of the crossover MCU: Bridging the power-performance gap

For years, engineers had to choose between the efficiency of a smaller and more integrated Microcontroller (MCU) and the high-performance complexity of an Application Processor (MPU). The emergence of so-called crossover MCUs has broken this dichotomy. By integrating multiple heterogeneous cores – such as a Cortex-M7 for performance and a Cortex-M4 for real-time tasks – these chips now offer MPU-level power with MCU-level efficiency.

This shift allows us to move away from expensive, power-hungry System-on-Modules (SOM) while retaining the ‘number-crunching’ ability needed for advanced encryption and on-device (artificial) intelligence.

Zephyr: The new standard for embedded portability

As MCUs become more complex, software must become more abstract. The Zephyr RTOS is becoming the “Linux of the embedded world”. Its vendor-independent architecture allows developers to write code that isn’t tied to a specific piece of silicon. Zephyr supports over 900 starter kits, demonstrating its broad adoption across MCU architectures and platforms.

In a landscape where regulatory requirements are becoming mandatory, Zephyr’s built-in security features, from secure boot to encrypted over-the-air (OTA) updates, provide more standardized options for compliance that was previously a custom-build challenge.

The edge AI paradigm: Intelligence without the tether

One of the defining characteristics of next-generation smart products is the ability to process data locally through Edge AI. Rather than relying exclusively on cloud-based intelligence, devices can make decisions closer to where data is generated.

This approach addresses several challenges associated with cloud-dependent IoT architectures, including:

• Latency: Local processing enables faster response times for time-critical actions.
• Privacy: Sensitive data remains on the device, reducing exposure and increasing user trust.
• Energy efficiency: Limiting high-bandwidth data transmission can significantly reduce power consumption.

Recent advances in AI techniques now allow complex neural networks to be optimized so they can run efficiently on cost-effective, low-power hardware.

The compliance catalyst: The role of the Cyber Resilience Act

Meeting high product requirements now includes meeting a new legal reality: the European Cyber Resilience Act. Security can no longer be a ‘patchwork’ effort added late in the cycle; it must be an architectural pillar.

The synergy of this ‘power trio’ provides a strategic path to compliance:

• Hardware-rooted trust: Crossover MCUs provide the physical foundation for secure boot and native encryption.
• Lifecycle management: Zephyr enables the secure OTA updates required to manage vulnerabilities throughout a product’s mandated support window.
• Data sovereignty: Edge AI naturally aligns with privacy-first mandates by reducing the attack surface of the product.

From complexity to synergy

The challenge of modern product development is that sophisticated features often lead to technical complexity, longer development cycles and higher costs. At the same time, products must meet increasingly strict security and regulatory requirements, often invisible to the end user, but critical for market access and long-term viability.

Understanding how the synergy between crossover hardware, scalable OS layers and edge intelligence can reduce engineering effort is key to delivering products that are intuitive and powerful, but also secure and compliant by design.

We are moving toward a future where ‘smart’ is no longer a feature, but an inherent, autonomous quality that evolves over time.

Edge AI makes products think smarter

Edge AI brings artificial intelligence directly to the device, or “the edge”, rather than relying solely on internet communication and cloud computing. Sensors, IoT devices and embedded systems can process data locally, make real-time decisions and adapt their behavior instantly. By offloading computation from the cloud, Edge AI enables faster responses, lower latency, reduced data transfer and improved privacy; all while optimizing power consumption and performance for embedded devices.

Why Edge AI makes your product breakthrough

Edge AI isn’t just about smarter technology; it’s about overcoming the everyday limitations that stop products from reaching their full potential.

• Limited or unstable data connections?
  Traditional cloud-based AI struggles when connectivity is poor. Edge AI makes real-time decisions locally, ensuring your product functions intelligently anywhere, anytime, without relying on constant internet access.
• Simple sensors, big insights
  Even basic sensors can deliver high-end performance with Edge AI. Through sensor fusion, devices combine data from multiple sources to act as virtual, intelligent sensors. For example, a washing machine can estimate drum fill by analyzing vibration and motor sound, avoiding the need for supplementary (more expensive) weight sensors.
• Need a longer product lifetime?
  Edge AI continuously monitors product health, predicting maintenance needs before failures occur. Changes in sound or vibration patterns can indicate wear in critical components, extending the product’s lifetime and reducing costly downtime.
• User interaction matters
  Edge AI enables local processing of audio and video, allowing products to interact intuitively with users while preserving privacy. From personalized feedback to detecting behaviors in sensitive environments (like for example, smoking detection in toilets), devices become smarter and more user-friendly.
• Harsh environments or complex interfaces?
  Edge AI supports intuitive interaction even in challenging conditions. Industrial terminals, for instance, can recognize hand movements contactlessly, ideal when workers wear thick gloves, making conventional touchscreens ineffective.

Turning Edge AI into customer value

By addressing these product-level challenges, Edge AI drives multiple benefits that customers care about:

• Improved user experience with immediate, intuitive responses.
• Personalized interfaces and automated behavior insights.
• Stronger privacy as raw data remains on the device.
• Predictive maintenance that reduces downtime and operational costs.
• Sustainability through lower energy consumption and optimized local processing.
• Enhanced business insights for smarter product evolution.
