LynxOS RTOS: Unprecedented Linux compatibility in an RTOS Real-time operating system with UNIX, POSIX and Linux interfaces

The LynxOS® RTOS is the most open hard real-time operating system available today. The native interfaces of this RTOS are those of Linux®, UNIX® and POSIX®.

The LynxOS RTOS is ABI-compatible with Linux, and is part of a family of open embedded operating systems from LynuxWorks™ that includes BlueCat® embedded Linux, LynxOS-178 and the LynxOS-SE RTOS.

Open APIs

Because the LynxOS RTOS is designed from the ground up for conformance to open system interfaces, OEMs are able to leverage existing Linux, UNIX and POSIX programming talent for embedded real-time projects. Real-time system development time is saved and programmers are able to be more productive using familiar methodologies as opposed to learning proprietary methods.

Full POSIX conformance

POSIX conformance means that OEMs can use the LynxOS RTOS to take advantage of existing POSIX-compliant applications—including open-source Linux and Solaris™ applications—to speed up time-to-market. Some real-time operating systems only comply with parts of the POSIX specification, but the LynxOS RTOS is fully conformant with POSIX interfaces for core services, real-time extensions, and thread extensions—POSIX 1003.1-2003 PSE 53 conformance.

True Linux compatibility

Linux ABI-compatibility has no impact on LynxOS kernel stability or maintainability, nor does it incur overhead as do usual compatibility layers. This is due to LynxOS RTOS' inherent compatibility with the interfaces of Linux, UNIX and POSIX.

Additionally, LynuxWorks development tools support LynxOS, LynxOS-178, LynxOS-SE and BlueCat Linux. Hence there are no new tools to purchase and no new learning curves to climb in order to extend code investments across both the open-source and hard real-time worlds.
