The Need For Increased Determinism and Ever-Shorter Latency Guarantees

Real-Time Operating Systems (RTOSs) are essential for the myriad 21st century applications that are driving the explosive need for real-time, reliable, and secure control of the systems and devices we depend on; systems which require determinism and the ability to guarantee worst case scenarios under load. RTOSs are especially critical for aerospace & defense applications with their need for real-time control and reliability for high performance flight control systems, radar systems, navigation systems, and command and control systems. But not all RTOSs are the same. This White Paper discusses the differences between a ‘soft’ and ‘hard’ RTOS, outlines the features of a robust RTOS, and provides a guide for understanding which features and factors to consider when selecting both a RTOS and the RTOS suppliers.
