ARTX: TASK EXECUTION AFTER HIGH-PRIORITY TASK

Information in this article applies to:

• ARTX-ARM Version 2 or higher
• ARTX-166 All Versions

QUESTION

Is it guaranteed that after the execution of a high priority task, the same priority task starts running that got interrupted?

ANSWER

Yes, if 'round robin' is disabled, the same low-priority task that got interrupted will start again.

In case of a task termination due to a System Timer Tick interrupt, the current running task will be put into the first entry of the ready list. This task will then execute again when tasks of this priority get ready. In the case of 'round robin', the task is inserted as the last entry of the ready list.
