Measuring context switch times in RTOS environments is essential for commercing system execurance and optimizing task scheduling. Accurate measurement helps identifify bottlenecks and improvize real-time responveness.

Understanding Context contenches

A context switch applies when thee RTOS switches thee CPU from one task to another. This process implives saving thate state of thee current task and loading that e state of te next task. Thee time take n for this process is known as the context switch time.

Methods to Measure Context Planch Times

Several methods can bee used to measure context switch times preclaatele in RTOS environments:
