Abstract
A method and apparatus for an innovative hardware independent interface to the external world. The interrupt services are part of an overall I/O model providing an object base I/O system that supports dynamic configuration of the system. The design of these interrupt exploit the advantages of Object Oriented Design (OOD) in an otherwise disorderly world of I/O. Object processing is designed into the architecture at the lowest level routines in the preferred embodiment of the invention. This includes an object oriented design all the way down to interrupt processing abstractions. These interrupt abstractions provide an architecturally sound framework for the dynamic installation, configuration, and timely execution of interrupt handlers.
