Real-Time Linux Applicability for Hard Real-Time Systems
Let’s get an in-depth understanding of real-time systems, analysing the real-time characteristics of two prominent operating systems: Linux with PREEMPT_RT patch and QNX. By examining their real-time characteristics, determinism, performance, and features, developers can get an idea of how the real-time behaviours of Linux with PREEMPT_RT patch compare with QNX.
Real-time operating systems (RTOS) play a critical role in the development of hard real-time systems and meeting the stringent timing requirements of real-time applications. QNX (Quantum Neutrino eXecutive) stands out as a preferred choice for hard real-time systems, such as medical systems, due to its real-time capabilities and features.
