Real-Time Operating Systems (RTOS) are designed to provide deterministic response within predefined time limits. This implies the ability to reliably and predeterminedly manage the flow of events and operations in an electronic system. Real-time Operating Systems are widely used in applications that require strict control of execution time, such as industrial control systems, medical equipment, autonomous vehicles, safety-critical systems and more. However, when the hardware on which the operating system is based is affected by ionizing radiation, such as during cosmic radiation events or failures in high-radiation environments, undesirable, even severe, effects may occur. Therefore, it becomes necessary to adopt a set of mitigation techniques at both the hardware and software levels.
