The Interrupt Aggregator provides a centralized machine which handles the termination of system events to that they can be coherently processed by the host(s) in the system. Both the signaling and content of K3 system events are incompatible with standard interrupt controllers. The INTR_AGGR provides mechanisms which convert the TI proprietary system events to standard level sensitive pending bits which can be used by the Interrupt Router and all downstream interrupt infrastructure. Events can be presented to the INTR_AGGR in two different forms:
In both cases, these events need to be conditioned to transition them from a transient indicator that something occurred to a persistent and reliable indication of the current state of the system. The INTR_AGGR is architected to perform this conversion in an efficient and cost effective manner.
