A [[software design pattern]] '''scheduled-task pattern''' is keep track of actions and invokes them these actions, and invokes them at the appropriate times. (Note: it is not quite the same as [[scheduler pattern]]).
'''Intent''': Ensure to ensure that desired operations are performed at specific points in the future.
'''Motivation''': In [[Real-time systems]], it is often necessary to ensure that something is done at a specific time. Times may be expressed as "wall time" or as some sort of internal time ("ticks", milliseconds-since-startup, etc.).
If highly accurate scheduling of tasks is needed (to milliseconds or less), the scheduler task needs to run at a very high [[priority]], or be hooked into a high-frequency [[interrupt routine]].
