In collaboration with Clément Gallin-Douathe, Practice Leader for Embedded and Critical Systems at Randstad Digital.
By 2031, the global market for embedded AI is expected to reach nearly $20 billion, up from $9.92 billion in 2023. This growth, driven by sectors as diverse as automotive, aerospace, healthcare, and the Internet of Things (IoT), confirms the enduring integration of artificial intelligence into industrial products.
While the potential is immense, integrating AI into embedded systems with limited computational resources poses a significant challenge for manufacturers. How can increasingly powerful technologies be integrated into embedded systems with constrained resources?
Balancing performance, security, compliance, energy efficiency, and accelerated development cycles is complex.
At Randstad Digital, our teams of embedded and critical systems specialists support companies through this technological transformation.
major technical constraints
Machine learning algorithms, particularly deep neural networks, require considerable computing and data volumes. However, embedded platforms—embedded computers in vehicles, connected sensors, smart medical devices—are inherently limited in memory capacity, processing power, and energy consumption. This gap between the needs of AI models and the capabilities of equipment creates a technological tension that few players know how to resolve today.
Additionally, there are five major industrial constraints:
-
securing AI models
In contexts where embedded systems are deployed in critical environments (aerospace, healthcare, defense), ensuring the integrity and robustness of AI models is essential. Attacks via malicious data injection (data poisoning) or imperceptible input modifications (adversarial attacks) can compromise system performance and safety. Moreover, the embedded nature of these models exposes them to reverse engineering or model extraction attempts, making protection mechanisms like encryption, anomaly detection, and the embedding of robust and interpretable models indispensable.
-
cost control
Solutions must remain economically viable while integrating cutting-edge technologies. In the home appliance or consumer electronics sector, margins are often thin. Manufacturers must integrate smart features into low-cost equipment without affecting profitability.
-
energy efficiency
An imperative for both performance and environmental certifications. In the automotive industry, while the popularization of electric vehicles aligns with climate change mitigation efforts, their range is crucial. A poorly optimized embedded AI model (like a driver fatigue detection system) can unnecessarily consume battery power. Similarly, in wearable connected devices, energy consumption is a critical factor for ensuring a full day of autonomy.
-
miniaturization
Embedded supports are increasingly compact, sometimes limiting hardware expansion possibilities. In the medical sector, there's an emergence of smart portable devices such as connected implants and cardiac monitors. These devices must embed real-time anomaly detection algorithms in a small space, without overheating, and with strict adherence to safety standards.
-
reducing time-to-market
Development cycles are accelerating, and manufacturers are increasingly adopting software development timelines. In the automotive industry, time-to-market has decreased from five to three years, but vehicles must still meet strict reliability and safety requirements.
a multidimensional optimization approach
Faced with these challenges, Randstad Digital teams deploy an advanced software optimization approach, capable of adapting AI models to constrained environments.
The methodology is based on fine-grained engineering at multiple levels:
- Model lightening: reducing algorithmic complexity without performance loss.
- Memory optimization: precise configuration of memory accesses, limitation of cache-misses, and fine management of buffers.
- Software rewriting: adaptation of libraries, optimized compilation, and rationalization of dependencies.
A project carried out for an aerospace manufacturer illustrates this expertise: Randstad Digital teams successfully integrated AI functionalities onto a computer installed for over ten years, without modifying the hardware. By reworking machine languages, parallelizing tasks, and redesigning the software architecture, they extended the equipment's operational lifespan while adding smart features.
an ongoing cultural transformation
However, the embedded AI challenge goes beyond the purely technological field. It's part of a broader transformation of industrial models. Like the automotive sector, where major car manufacturers are increasingly turning into technology players to create Software Defined Vehicles (SDVs). BMW was the first to internalize its software teams, followed by Renault with the acquisition of an Intel division and the creation of Ampere.
This shift profoundly alters industrial engineering cultures: agile methods and frameworks like SAFe are gaining ground in software teams, while V-cycles remain the norm for hardware. To support this hybridization, Randstad Digital offers comprehensive support, including agile coaching, technical training, team acculturation, and certification preparation.
an opportunity to seize
Integrating artificial intelligence into embedded systems represents a strategic turning point for industry. While it imposes complex constraints, it also opens up unprecedented innovation opportunities. The ability to combine performance, efficiency, reliability, and speed becomes a key differentiator in markets. Manufacturers have every interest in paying close attention to technological developments in other sectors.
For manufacturers, these challenges can become levers for innovation, provided they are supported by technical partners capable of understanding both business issues and technological specificities. In this sense, collaborations between solution providers like Randstad Digital and industrial clients are shaping a new era of embedded engineering—more agile, smarter, and more integrated.
