Hardware event treating in nMPRA

In real-time systems, events treating is one of the most important aspects. There can be time events, watchdog timer events, deadline events, interrupt events, mutex events, and synchronization and inter-task communication events. Since multiple events can occur simultaneously, it is important to find a way to select the order in which the events will be treated. For that, in this paper it is presented a method of global prioritization of the events by category using a hardware prioritization scheme for the n-task Multi Pipeline Register Architecture (nMPRA) and an analysis of how are treated mutex and inter-task communication events in the same architecture.
