Real-Time OS Basics: Picking The Right RTOS When You Need One

WebApr 1, 2003 · Webinar: How to Prioritize RTOS Tasks (and Why it Matters) Preemption tradeoffs. The memory costs of using a preemptive scheduler include extra ROM for the system calls plus RAM for task-specific stacks. Other costs are measured in lost CPU time. For example, the scheduler is software that consumes processor cycles. WebThe scheduler will periodically switch execution between ready state tasks of the same priority (in a round robin fashion). Time slicing is governed by a tick interrupt. The ESP-IDF FreeRTOS scheduler supports the same scheduling features (i.e., Fixed Priority, Preemption, and Time Slicing) albeit with some small behavioral differences.
