Wind River redesigns RTOS for Internet of Things

Wind River reinvents VxWorks to create Version 7. This new version provides a secure microkernel as small as 20KB to run edge nodes in the Internet of Things. Networking stacks can be added for connectivity up to around 100KB.

A combination of the microkernel and the standard kernel, built on the same VxWorks platform, allows designers to reduce development and maintenance costs by using one RTOS across different cores, big and small.

Wind River's owner Intel is taking this approach with different versions of its Quark core. It can also be applied across different classes of connected devices, from small-footprint consumer wearables to large networking equipment and everything in between.

A new modular approach allows customers to apply targeted, efficient upgrades to packages and protocols without changing the system core, which minimises testing and recertification efforts, and allows customers to sustain their systems on the cutting edge of technology. Version 7 also includes a comprehensive set of built-in security features, which includes secure data storage, tamper proof design, secure upgrade, root of trust, and user and policy management as well as a secure bootloader with hooks into ARM's TrustZone.

This version adds support for a broad range of standards and protocols such as USB, CAN, Bluetooth, FireWire and Continua, as well as networking capabilities. The graphics-ready platform includes a stack based on the published OpenVG API, hardware-assisted graphics drivers and the Tilcon graphics designer tool as well as OpenGL ES support.
