ThunderX integrates SAFERTOS for cockpit-ADAS fusion

ThunderX has recently made the decision to implement SAFERTOS across its next-generation AI domain controller platforms that are built on Qualcomm automotive SoCs. This move is aimed at supporting cockpit-ADAS fusion in software-defined vehicles, with a focus on selected safety-critical subsystems. The real-time operating system is expected to provide deterministic execution and a clearer functional safety path for OEM programmes.

For readers of eeNews Europe, this announcement holds significance as it sheds light on the practical software layer driving the shift towards centralized vehicle compute. It also demonstrates how suppliers are striving to make mixed workloads, ranging from ADAS to in-cabin AI, more manageable on shared automotive platforms.

Centralised Compute Needs a Safety Layer

As automotive manufacturers transition towards AI-driven, centralized electronic architectures, the challenge goes beyond simply increasing computational power. It now involves ensuring that time-critical functions remain predictable as cockpit, ADAS, and AI workloads become more intertwined. ThunderX has disclosed that it is leveraging SAFERTOS within specific safety-critical components of its AIBOX platform family, which is centered around Qualcomm SA8775P and SA8650P devices.

The AIBOX platform is positioned as a central compute solution for various functions such as AI perception, driver monitoring, generative AI assistants, and cross-domain orchestration. While consolidating these functions onto fewer controllers can streamline system design, it also intensifies the need for effective scheduling, isolation, and safety compliance. Utilizing a pre-certified RTOS like SAFERTOS could potentially reduce the software integration burden for OEMs and Tier 1 suppliers working across multiple vehicle lines.

“Automotive OEMs are not only centralizing compute – they are deeply embedding AI into the vehicle architecture,” stated Dongchao Xu, CEO of ThunderX. “Through SAFERTOS, we are enhancing the deterministic real-time and functional safety foundation for safety-critical components within our platform architecture, enabling OEMs to scale AI-driven cockpit-ADAS fusion with reduced integration complexity and accelerated time to production.”

From Flagship Controllers to Broader Vehicle Lines

ThunderX has specifically highlighted two components of its controller portfolio. The RazorDCX Tarkine, based on Qualcomm’s SA8775P, is described as a single-SoC cockpit-driver fusion controller that integrates HMI, connectivity, in-cabin vision, and ADAS support. Within this platform, SAFERTOS operates on Cortex-R52 cores within the safety subsystem to facilitate real-time ADAS control.

Additionally, the company introduced the RazorDCX Pantanal, which is built on the SA8650P and extends the same architectural approach across various vehicle segments, from entry-level models to higher-end platforms. Employing the same safety software foundation across different product lines could offer OEMs a more cohesive development model while still allowing for cost and performance scalability.
