History

The first versions of LynxOS were written in 1986 in

Intel 80386 architecture. Around 1989, application binary interface (ABI) compatibility with UNIX System V
.3 was added. Compatibility with other operating systems, including Linux, followed.

Full Memory Management Unit support has been included in the

ARM Cortex A-family.[3]

LynxOS components are designed for absolute determinism (hard real-time performance), which means that they respond within a known period of time. Predictable response times are ensured even in the presence of heavy input/output (I/O) due to the kernel's unique threading model, which allows interrupt routines to be very short and fast.

Lynx holds an expired patent on the technology that LynxOS uses to maintain hard real-time performance. U.S. patent 5,469,571 was granted to Lynx November 21, 1995: "Operating System Architecture using Multiple Priority Light Weight kernel Task-based Interrupt Handling."

In 2003, Lynx introduced a specialized version of LynxOS named LynxOS-178, especially for use in avionics applications that require certification to industry standards such as DO-178B.

In late 2022, support for the programming language Rust was added to the certified toolchain for LynxOS-178 and LynxElement unikernel.[4]

The Usenet newsgroup comp.os.lynx is devoted to discussion of LynxOS.
