Abstract
In a multiprocessor system of the type in which two or more separate processor modules are connected by an interprocessor bus dedicated exclusively to interprocessor communication for parallel processing, there is provided an input/output system having multiported device controllers connected to the multiprocessor system by input/output buses. Each device controller is shared by pairs of the processor modules, and includes logic that ensures that only one port is selected for access at a time.
