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.
