An RTOS task is scheduled when a scheduling event upon which it is waiting occurs, of which time is just one such event and the least appropriate if real-time response to asynchronous external events is required. WebScheduling: RTOS offer scheduling capabilities to define how tasks should be scheduled and executed over time, including priorities, periodic updates and deadlines. Task Synchronization: Tasks running concurrently may need to exchange data or synchronize in some way. RTOS allows for these operations by providing various synchronization ...
