A Small, Scalable Open Source RTOS for IoT Embedded Devices
The Zephyr Project, a Linux Foundation hosted Collaboration Project, is an open source collaborative effort uniting leaders from across the industry to build a best-in-breed small, scalable, real-time operating system (RTOS) optimized for resource-constrained devices, across multiple architectures.
he Zephyr Project’s goal is to establish a neutral project where silicon vendors, OEMs, ODMs, ISVs, and OSVs can contribute technology to reduce the cost and accelerate time to market for developing the billions of devices that will make up the majority of the Internet of Things
The Zephyr Project is perfect for building simple connected sensors, LED wearables, up to modems and small IoT wireless gateways. Because the Zephyr OS is modular and supports multiple architectures, developers are able to easily tailor an optimal solution to meet their needs. As a true open source project, the community can evolve the project to support new hardware, developer tools, sensor and device drivers. Enhancements in security, device management capabilities, connectivity stacks and file systems can be easily implemented.
The Zephyr kernel is derived from Wind River’s commercial VxWorks Microkernel Profile for VxWorks. Microkernel Profile has evolved over 20 years from DSP RTOS technology known as Virtuoso. The RTOS has been used in several commercial applications including satellites, military command and control communications, radar, telecommunications and image processing. The most recent example of the technology’s success is the successful Philae Landing on Comet Churyumov–Gerasimenko and the accompanying Rosetta Orbiter.
Features of Zephyr Project
- Developed with security in mind
- Employs an in-depth security development lifecycle: security validation, fuzz and penetration testing, frequent code reviews, static code analysis, threat modeling and reviews to prevent backdoors in the code
- The project’s governance includes the formation of a security working group and a delegated security maintainer
- The governance and its members have the responsibility to ensure that all aspects of the code are developed securely
- Available through the Apache 2.0 open source license
- Free to use in commercial and non-commercial solutions
- Hosted as a collaborative project with the Linux Foundation, the project is neutrally governed employing a lightweight governance and development model
- From professional makers to large industrial and commercial vendors, the Zephyr Project strives to deliver a universally adoptable solution for the Internet of Things.
- Zephyr Project provides developers with feature-rich software optimized for memory constrained devices.
- Runs on systems as small as 8 kB of memory to more than 512 kB
- Complete freedom – use the RTOS as-is or tailor a solution by enabling/disabling nearly every feature using Kconfig
- Developers can use their tool suite of choice by supporting custom toolchains and compiler optimizations
- Optimized for low-powered, small memory footprint devices
- Supports Bluetooth®, Bluetooth® Low Energy, Wi-Fi*, 802.15.4
- Supports standards like 6Lowpan, CoAP, IPv4, IPv6, and NFC
- Refined and enhanced functionality through community-driven development
