An object-oriented input/output (IO) system represents an interface between clients of the IO system and peripheral devices, such that the clients can access the peripheral devices by utilizing IO services offered by the IO system. The IO system includes one or more object-oriented IO servicers for receiving IO service requests from clients, and for generating IO commands in accordance with the IO service requests. One or more object-oriented access managers, coupled to the IO servicers and the peripheral devices, access the peripheral devices as instructed by the IO commands such that the IO service requests are satisfied. The peripheral devices may transmit interrupts to a kernel while operating in acordance with the IO commands. One or more object-oriented interrupt servicers, coupled to the kernel, receive and decode the interrupts from the peripheral devices. One or more object-oriented interrupt handlers, coupled to the interrupt servicers, process the decoded interrupts. The IO system cited here includes an operating system independent execution environment for the various I/O servicers, each of which is designed in such a way as to support a variety of interchangeable operating systems.
