ABSTRACT A multiprocessor system has a plurality of proces- sors and a memory unit which are interconnected through a common bus. Each processor communicates with the memory through the bus. Communication among processors is also ef- fected by storing in memory, into memory zones the messages intended for the several processors, each dedicated to one processor but accessible to all the processors. This operation is performed using the common bus and the normal memory communication procedure. A notify signal is sent on the common bus and identified by the only processor for which it is intended. The notifying signal is memorized by the notified processor without interrupting its continued operation and is taken into account in a completely auto- nomous way as to the notifying processor. The identification of the notifying signal causes the notified processor sub- sequently to access the memory unit and read out the message.
