Summary:Queue storage queues event entries from a hardware event detector that are to be communicated to a software event handler. An event register stores a most recently received event entry. A comparator compares a newly received event entry with the content of the event register and if a match occurs, then these event entries are merged by setting a merged entry bit and discarding the newly received event entry. When a non-matching event entry is received, then the unqueued event within the event register is stored into the queue storage. If the queue storage is empty, then the event register and the comparator are bypassed. When the queue storage becomes empty, then any currently unqueued event within the event register is stored into the queue storage. The event entries may be translation error event entries in a system which translates between virtual addresses and physical addresses.
