ABSTRACT:
In a system comprising data-processing units, some of which are masters and others of which are slaves, all the units are connected to a common bus via interface circuits. Only the master units are capable of acquiring instantaneous control of the bus by means of a resource allocation device. By utilizing a set of three basic control signals carried by the bus, three distinct addressing modes can be established: master-to-master, master-to-slave, general master-broadcasting to all units in accordance with a number of chronologies and transmission modes. In an alternative embodiment, substitutions of addresses can be performed directly on the bus.
