An RTOS provides the rigorous resource management and scheduling required to meet the demands of applications– with multitasking, threads, priority-driven preemptive scheduling, and fast context-switching - all essential features of an embedded real-time system.Īn RTOS typically has a small footprint and is optimized for performance, however each RTOS must be customized with capabilities needed for the hardware and system it supports. Many embedded systems require real-time behavior, and due to hardware resource constraints, performance and efficiency are top priorities. When the OS must handle multiple events concurrently and ensure that the system responds to those events within predictable time limits, it is called a real-time operating system, or RTOS. The main responsibility of an operating system is to manage hardware resources and activities in the system: scheduling application programs, writing files to disk, sending data across a network, and so on.
