From powering life-critical medical devices to guiding spacecraft on interplanetary missions, real-time operating systems (RTOS) form the invisible foundation of our modern world. At the forefront of this technology stands VxWorks, a software marvel developed by Wind River that has continually adapted to meet the complex demands of the embedded systems landscape.
Proven Performance, Mission-Critical Reliability #
VxWorks ensures deterministic behavior: given the same input, it delivers the same result, at the same time, every time. It’s the RTOS behind countless innovations — from driver assistance systems and robotic surgery to planetary rovers and aerospace defense systems.
As embedded computing evolved from isolated systems to intelligent edge platforms, VxWorks has kept pace, incorporating cutting-edge features without compromising its core: predictable, high-performance real-time execution.
Innovation Across the Stack #
Enabling AI and ML at the Edge #
Once exclusive to the cloud, artificial intelligence (AI) and machine learning (ML) now operate directly on edge devices. VxWorks enables this shift by supporting modern data science libraries:
- NumPy (2020) and Pandas (2021) for data processing
- TensorFlow Lite (2021) for lightweight ML model deployment
These capabilities empower edge applications like image recognition in defense, predictive maintenance in vehicles, and faster diagnostics in healthcare.
Time-Sensitive Networking (TSN) #
To address the limitations of traditional Ethernet in real-time environments, VxWorks introduced TSN support in 2016, enabling:
- Time synchronization
- Bounded latency
- Deterministic packet delivery
The RTOS now supports TSN across Intel® and Arm® platforms, as well as deployment within virtual machines (VMs) via Wind River Helix™ Virtualization Platform, validated with no performance degradation (2024 milestone).
💡 Industry 4.0 integration was further enhanced by adding the open62541 OPC UA stack over TSN in 2020.
Designed for Certification and Multicore Scale #
Functional Safety at Scale #
VxWorks supports high-assurance certification standards across industries:
- Aerospace: DO-178C DAL A
- Automotive: ISO 26262 ASIL D
- Medical: IEC 62304 Class C
- Industrial: IEC 61508 SIL 3
Over 600 projects have leveraged VxWorks’ pre-certified components to streamline safety certification. It provides comprehensive tooling to address interference challenges in multicore processors, based on techniques published in collaboration with Rapita Systems.
Multicore and 64-bit Support #
Since 2014, VxWorks has supported multi-core and 64-bit architectures while maintaining low and predictable system overhead—crucial for high-performance real-time workloads.
Built for Developer Agility #
Extensive BSP Ecosystem #
With support for Arm, RISC-V, x86, PPC and more, VxWorks offers an extensive library of Board Support Packages (BSPs). In 2020, VxWorks added RISC-V support, enabling development on open silicon without vendor lock-in or royalties.
Custom BSPs are also available through Wind River Professional Services for projects with unique hardware needs.
Modern Language Support #
VxWorks embraces modern software practices by supporting popular programming languages:
- Python (2020): rapid scripting and modular design
- Rust (2019): memory-safe concurrency and robust security
- GNAT Pro for Rust (2024): added via AdaCore partnership
These enable teams to build secure, maintainable systems more efficiently.
Cloud-Native Development and DevSecOps #
With the release of Wind River Studio Developer in 2021, VxWorks became the first RTOS to offer a cloud-native DevSecOps toolchain. Features include:
- Integrated CI/CD pipelines
- Cloud-based debugging and testing
- Secure deployment and updates
Containers and Kubernetes #
VxWorks leads the embedded space in containerization:
- OCI container support (2021)
- Kubernetes orchestration (2023)
This allows embedded teams to standardize their workflows, minimize errors, and deploy updates faster.
Securing the Intelligent Edge #
Security is not optional — it’s fundamental. Since 2022, Wind River has applied a Secure Development Lifecycle (SDL) based on NIST SP 800-218 (SSDF), ensuring product integrity from design to deployment. VxWorks is also backed by Wind River Security Center for vulnerability tracking and mitigation.
Looking Ahead #
The journey of VxWorks is far from over. As the embedded systems industry confronts new frontiers — AI at the edge, TSN evolution, increasing safety demands, and ever-more powerful multicore architectures — VxWorks remains a trusted partner.
Whether you’re building next-gen medical devices, smart vehicles, or aerospace platforms, when it matters, it runs on VxWorks.
