VxWorks Overview

VxWorks The Leading RTOS
The industry's most widely deployed RTOS.

VxWorks has been used to ensure the security, safety, and reliability you need to design and build mission-critical embedded systems that simply must work.

Why VxWorks ?

#

Real-time embedded systems need a robust real-time operating system (RTOS) that leverages the latest and greatest enhancements in processor and hardware technology.

VxWorks RTOS is the industry leading real-time operating system (RTOS). For more than 35 years, the VxWorks® real-time operating system (RTOS) has been chosen by global industry leaders as the trusted foundation to power billions of safety-critical intelligent devices, machines, and systems. Its rich functionality helps customers deploy innovative products while lowering costs and shortening production cycles.

Why is VxWorks the RTOS for your next project ?

#

Key characteristic of VxWorks

#

• Proven: VxWorks is the RTOS that powers more than 1 billion real-time systems across the globe, from small consumer products to commercial airliners. When the consequences for failure are expensive or, worse, life threatening, the VxWorks RTOS is the only choice. After 30 years of RTOS leadership and consistently successful deployments, Wind River is the name you know you can trust.

• Optimised: The VxWorks RTOS has been optimised for performance, determinism, and code footprint on each processor platform it runs on. The VxWorks RTOS is also optimised for specialised hardware support for such features as network acceleration and graphics. Why waste processing power on a non-optimised RTOS?

• Innovative: The first RTOS with 32-bit and 64-bit processing, multi-core and multi-OS support, and diverse connectivity options, VxWorks provides our customers with the leading-edge RTOS functionality they require to stay competitive. Why go with an RTOS that doesn’t provide the solutions you need to take advantage of the latest technology?

Unparalleled Innovation

#

VxWorks drives RTOS innovation in key requirement areas for embedded systems. By their very nature, embedded systems are constrained by memory, performance, and power consumption. Application requirements continuously grow to satisfy new safety and security standards and customer value criteria such as rich user interfaces and connectivity. VxWorks meets these growing requirements with unparalleled RTOS innovation:

• Multi-core/multi-OS: VxWorks is designed for use in various multi-core configurations as a single operating system in symmetrical multiprocessing (SMP) and asymmetrical multiprocessing (AMP) modes or as a guest RTOS on top of Wind River Hypervisor.

• Scalability: VxWorks offers robust and reliable RTOS performance on small memory- and CPU-constrained devices up to full 64-bit multi-core systems for high-end processing. Because of this scalability, VxWorks is the ideal RTOS for creating a common software platform for a product line of embedded devices.

• Security and safety: Our leadership in safe and secure systems includes a certifiable RTOS for very stringent safety standards such as FAA/RTCA DO-178B/EUROCAE ED-12B Level A, IEC 61508, and ARINC 653. VxWorks also provides a multilevel secure (MLS), High Robustness RTOS for the demanding requirements of the Common Criteria and National Information Assurance Partnership (NIAP). VxWorks is the first RTOS to be certified under Wurldtech’s Achilles certification program, an internationally recognized standard for industrial cyber-security.

• Connectivity: VxWorks provides industry-leading advanced networking solutions for every facet of embedded systems communications, from device to device via USB, and core to core in an AMP multi-core system with MIPC.

• Graphics: VxWorks RTOS and Wind River Media Library form a robust platform for embedded graphics solutions. With Wind River Tilcon Graphics Suite, developers have a complete graphical user interface (GUI) development system for next-generation devices.

Significant Strengths

#

At Wind River, we take pride in the innovations in VxWorks that have made it the No. 1 RTOS in the world, and we’re committed to continued innovation in each of our core strength areas:

• Footprint: VxWorks has a completely configurable and tunable small memory footprint for today’s memory-constrained systems. You control how much of the operating system you need.

• Real-time performance: Capable of dealing with the most demanding time constraints, VxWorks is a high-performance RTOS tuned for both determinism and responsiveness.

• Reliability: A high-reliability RTOS, VxWorks provides certification evidence required by strict security standards. Even for non-safety-critical systems, VxWorks is counted on to run forever, error free.

• Scalability: An indispensable RTOS foundation for very small-scale devices, large-scale networking systems, and everything in between, VxWorks is the first RTOS to provide full 64-bit processing to support the ever growing data requirements for embedded real-time systems. VxWorks is scalable in terms of memory footprint and functionality; you will tune it to the exact needs of your project.
