Scheduler flexibility enables a wider, computer-system orchestration of process priorities, but a real-time OS is more frequently dedicated to a narrow set of applications.

Īn RTOS has an advanced algorithm for scheduling.

An RTOS that can usually or generally meet a deadline is a soft real-time OS, but if it can meet a deadline deterministically it is a hard real-time OS. The chief design goal is not high throughput, but rather a guarantee of a soft or hard performance category.

A late answer is a wrong answer in a hard RTOS while a late answer is acceptable in a soft RTOS. A 'hard' real-time operating system (hard RTOS) has less jitter than a 'soft' real-time operating system (soft RTOS). Characteristics Ī key characteristic of an RTOS is the level of its consistency concerning the amount of time it takes to accept and complete an application's task the variability is ' jitter'. Event-driven systems switch between tasks based on their priorities, while time-sharing systems switch the task based on clock interrupts. Real-time operating systems are event-driven and preemptive, meaning the OS can monitor the relevant priority of competing tasks, and make changes to the task priority. All processing must occur within the defined constraints. Processing time requirements need to be fully understood and bound rather than just kept as a minimum. An RTOS is distinct from a time-sharing operating system, such as Unix, which manages the sharing of system resources with a scheduler, data buffers, or fixed task prioritization in a multitasking or multiprogramming environment. Computer operating system for applications with critical timing constraintsĪ real-time operating system ( RTOS) is an operating system (OS) for real-time computing applications that processes data and events that have critically defined time constraints.
