Article for providing event handling functionality in a processor supporting different instruction sets

An article comprising a machine readable medium having stored thereon a plurality of instructions which, if executed by a machine, cause the machine to perform operations comprising:

• responsive to detecting the occurrence of an event arising as a result of processing instructions from either a first or a second instruction set, wherein problems arising during the processing of instructions from said first and second instruction sets respectively causes a first and second set of events, performing the following,
• calculating the address of one of a first plurality of event handlers written to handle said event, wherein at least some of said first set of events are assigned to different ones of said first plurality of event handlers, and all of said second set of events are mapped to a first of said first plurality of event handlers;
• and
• executing the event handler stored at the calculated address.

An article comprising a machine readable medium having stored thereon a plurality of instructions which, if executed by a machine, cause the machine to perform operations comprising:

• responsive to detecting an event indicating a problem has arisen during the processing of instructions from a first instruction set and recording which of a first plurality of events has occurred, performing the following, calculating the address of a first of a first plurality of event handlers,
• wherein said first plurality of event handlers are stored in an event handling region, said event handling region being divided into sections with each section storing one of said first plurality of event handlers;
• executing the one of said first plurality of event handlers stored at said calculated address, said executing including,
• determining which of said first plurality of events has occurred based on said record, wherein each entry of an interrupt vector table is assigned to one of said first plurality of events, said entries having stored therein data identifying different ones of a second plurality of event handlers;
• and
• accessing the entry of the interrupt vector table for the detected event;
• and
• executing the one of said second plurality of event handlers identified by the accessed entry in the interrupt vector table.
