Abstract
An object-oriented interrupt processing system in a computer system creates a system database including a device namespace containing an entry for each device in the computer system and an interrupt namespace containing each entry in the interrupt source, arranged as an Interrupt Source Tree. Each entry in the Interrupt Source Tree is cross-referenced to a corresponding entry in the device namespace and contains a reference to an interrupt handler for the corresponding interrupt source. When an interrupt occurs, a single interrupt dispatcher is invoked, to access the Interrupt Source Tree and cause execution of the corresponding interrupt handler.
