LynxOS RTOS The real-time operating system for complex embedded systems

The LynxOS® RTOS (real-time operating system) is the superior foundation for sophisticated real-time systems:

20 years of RTOS experience goes into LynxOS. Broad conformance to open and de facto standards like Linux®, POSIX and UNIX® means that you can confidently build products with the LynxOS RTOS to meet the most stringent requirements for real-time mission-critical applications. Enjoy the time-to-market and investment-protection advantages of open standards-based development using the LynxOS RTOS.

RTOS security gets a boost with new LynxOS 7.0 features that allow developers to build secure embedded systems that are more secure than ever. Read about the new RTOS security in our LynxOS 7.0 announcement.

Features in LynxOS RTOS 5.0

  • Increased RAM support—up to 2 GB
  • Symmetric MultiProcessing (SMP)
  • New GNU toolchain—based on gcc 3.4.3 and GDB 6.5
  • ELF file format
  • Ada support
  • New POSIX—POSIX 1003.1-2003 PSE 53/54
  • Updated Linux Application Binary Interface (ABI) compatibility—Linux 2.6-based
  • USB 2.0
  • NFS v2 support
  • Serial ATA support

Real-time determinism

All RTOS components within LynxOS are designed for absolute determinism (i.e.: hard real-time performance). This means that they absolutely must respond within a known period of time. This predictable response is ensured even in the presence of heavy I/O due to the kernel's unique threading model, enabling interrupt routines to be extremely short and fast.

  • Perform complex series of tasks within set periods of time
  • Support multiple applications with multiple interrupting devices
  • Take full advantage of today's powerful high-end microprocessor and advanced networking architecture

True linear scalability

The LynxOS RTOS also exhibits true linear scalability, so that it stays unwaveringly deterministic even as the tasks it performs increase massively. And this determinism extends to networking applications, which can stay responsive even in the face of the most complex demands.
