ABSTRACT:
In a multiprocessor system comprising a plurality of individual processor modules interconnected by a bus structure, including a bus controller, for providing communication between the processor modules, a method and apparatus for interprocessor communication includes one of the processor modules sending a request signal to the bus controller to request a transmission; the bus controller polling the processor modules to identify the requesting processor module; the requestor processor module responding to the poll with the identification of the receiver processor module; the bus controller interrogating the receiver processor module to determine its status (i.e., busy or available); and the bus controller then signaling transmission commencement.
