Some methods, which include tricky-serious-time devices need a promise that an action is taken in the (usually shorter) constant maximum time recognised ahead of execution starts off. These kinds of programs can use his explanation exceptions only when there is Software assistance for properly predicting the most time and energy to Get better from a toss.
