RTOS stands for Real-Time Operating System. An RTOS is an operating system designed to perform real-time tasks that must be completed within a specific time frame. Real-time tasks are those that have deadlines, and if the task is not completed within the deadline, it can result in system failure.
An RTOS is typically used in embedded systems, which are specialized computer systems designed to perform specific tasks. Examples of embedded systems include automotive systems, medical equipment, and industrial control systems.
Some of the features of an RTOS include:
Task scheduling:
An RTOS must be able to prioritize tasks and schedule them in a way that ensures that real-time tasks are completed within their deadlines.
Interrupt handling:
An RTOS must be able to handle interrupts quickly and efficiently to ensure that real-time tasks are not disrupted.
Memory management:
An RTOS must be able to manage memory efficiently to ensure that real-time tasks have access to the memory they need.
Communication:
An RTOS must be able to handle communication between tasks and devices efficiently.
Overall, an RTOS is designed to provide reliable and predictable performance in real-time systems, making it a critical component in many embedded systems.
