Abstract

Systems, methodologies, media, and other embodiments associated with a system configured with a trap mode register, multiple interrupt vector address registers, and multiple interrupt vector tables are described. One exemplary system embodiment includes a logic for initializing the trap mode register, for initializing interrupt vector address registers, and for initializing interrupt vector tables. When a trap occurs in a computer configured with the exemplary system, the trap mode register may select, based, for example, on the trap type or a trap data, an associated interrupt vector address register to provide an address of an interrupt vector table through which a trap handler can be invoked.
