LynxOS

Company:

LynuxWorks

Description:

Designed for Real-Time: LynxOS is a UNIX-compatible, POSIX-conforming, multiprocess, and multithreaded operating system designed for complex real-time applications that require fast, deterministic response. The LynxOS kernel was specifically designed for hard real-time applications. Since its first release in 1988, LynxOS has been fully pre-emptible, re-entrant, and compact.

Modular Design: The modularity inherent in the LynxOS architecture makes the operating system highly scalable and configurable. At its smallest, LynxOS can be configured with only the kernel and linked with an application to form a ROMable image for specialized embedded applications. At its fullest, LynxOS is a self-hosted development environment consisting of a wide array of software development tools, UNIX-compatible utilities, industry standard networking, a graphical user interface, and a UNIX-like hierarchical file system.

Strong Adherence to Standards: LynxOS conforms to the POSIX 1003.1 system call interface standard and has been implemented according to the POSIX 1003.1b real-time extensions and the 1003.1c threads extensions. LynxOS includes the 4.4 BSD system call interfaces and libraries, which provide a high degree of source-level compatibility for applications written in either flavor of UNIX.
