Introduction to Real-Time Operating Systems

Real time Operating systems (RTOS) are special operating systems designed to complete operations within a certain time constraint. Unlike traditional operating systems, RTOSs prioritize tasks and ensure that critical operations are executed on time. Thanks to these features, they are widely used in many areas such as industrial automation, aviation, healthcare, and automotive. The main purpose of RTOSs is to ensure system stability and reliability by exhibiting deterministic behavior, i.e. always responding within the same time frame.

Real time In the design of systems, latency and responsiveness are critical. These systems manage hardware resources efficiently, ensuring that the highest priority tasks are completed in the shortest time possible. RTOSs are typically designed to be small in size and have low resource consumption, making them ideal for embedded systems. Interrupt management and intertask communication mechanisms are also key components of RTOSs.

• Basic Features of Real-Time Operating Systems
• Prioritized Task Management: By assigning priorities to tasks, critical operations are completed on time.
• Deterministic Behavior: Always gives consistent responses within the same time frame.
• Low Latency: Minimizes delays by responding quickly to inputs.
• Outage Management: Effectively manages hardware and software outages.
• Inter-Task Communication: Provides data exchange and synchronization between tasks.
• Small Size and Low Resource Consumption: Optimized for use in embedded systems.

The performance and reliability of RTOSs are critical to the success of the system design and implementation. Therefore, RTOS selection and configuration should be carefully tailored to the application requirements. For example, hard real time systems can cause system failure if a task cannot be completed within the specified time frame, while soft real time In case of a timeout in these systems, an acceptable performance degradation may occur.
