Embedded systems have transformed dramatically: What once were simple single-core setups have evolved into complex multi-core architectures, driven by demands for efficiency, security, and connectivity. This TechCast examines how balancing innovation with strict certification requirements becomes increasingly vital in safety-critical domains like avionics. It also explores the growing role of open-source software as a catalyst for embedded innovation.
From Simplicity to Complexity: The Embedded System Paradigm Shift
The embedded industry has moved from systems where a single core and external IoT chips were the norm to highly integrated multi-core environments. As systems grow more complex, the industry’s familiarity with low-level hardware intricacies has diminished. Developers now rely more on high-level OS abstraction—configuring applications rather than working close to the silicon.
Efficiency vs. Excess: Right-sizing System Resources
Modern SoCs pack an array of functionalities—many of which go unused. The challenge lies in trimming unnecessary features to optimize power consumption while retaining certification integrity. It’s increasingly important to “simplify the complex” by removing unneeded capabilities from already integrated platforms.
Open-Source as an Advantage - When managed correctly
Open-source software, once seen as a threat, is now a vital innovation driver. It enables support for new hardware and technologies more rapidly than closed ecosystems. The key is mixed-criticality architecture: safely combining open-source elements (e.g., drivers, UIs) with real-time certified components to leverage flexibility without compromising safety.
Conclusion
The embedded landscape is shifting toward high-performance, connected multi-core systems—creating new challenges in certification, resource optimization, and maintaining low-level expertise. At the same time, open-source, when integrated within a safety-aware architecture, serves as a powerful enabler of innovation. As embedded systems continue to evolve, embracing both precision and adaptability will be essential.
