ABSTRACT:
An out-of-order microprocessor signals event occurrence and provides event handling information utilizing a novel instruction issued to an execution unit upon detection of the condition giving rise to the event. Event information includes the type of event and characteristic information and data for use by a coded routine which handles the event. A reorder buffer stores this information to facilitate event handling actions and state updates. A retirement control circuit of the microprocessor includes a posting mechanism for use by the event handling routine.
