A legacy of functional safety

Wind River, the leader in software for complex, connected, safety-critical systems, supports the Arm®, Intel®, and PowerPC® architectures for DO-178C software considerations in airborne systems, IEC 61508 functional safety, and ISO 26262 automotive safety.



VxWorks: The RTOS Foundation for Embedded Innovation in Billions of Devices, Machines, and Systems

VxWorks has been the industry-leading real-time operating systems (RTOS) for building embedded devices and systems for more than 30 years. Its rich functionality, high performance, determinism, low latency, and modern development processes help our customers deploy innovative products while lowering costs and shortening production cycles.


As a deterministic, priority-based preemptive RTOS with low latency and minimal jitter, VxWorks is ideal for hard real-time embedded applications.


VxWorks includes many advanced security features to address the evolving security threats connected devices face at all stages, from boot-up to operation to data transmission to powered off.


Safety features such as time and space partitioning have been leveraged in the certification of VxWorks to DO-178C, IEC 61508, and ISO 26262 safety standards.


Built on an upgradeable, future-proof architecture, VxWorks helps you rapidly respond to changing market requirements, customer needs, and technology advancements, preserving your investment.
