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 an entry for each interrupt source, arranged as an Interrupt Source Tree. Each entry in the Interrupt Source Tree is cross-referenced to a corresponding entry in the 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.

Method and apparatus for object-oriented interrupt system

A method and apparatus for providing memory functionality to object-oriented client software components of a computer system having a CPU using a first set of memory classes, each class of the first set being platform-independent; a second set of memory classes, each class of the second set being a subclass of a class of the first set and being platform-dependent; and performing client component memory functions by accessing only objects of classes of the first set. Descriptions of the classes and methods are provided, enabling platform-independent device drivers to be implemented.
