ABSTRACT:
A multi-processor data processing system comprises, in addition to a main memory unit which is common to a plurality of processors, a queue buffer which is common to the processors to store intercommunicating information for the processors, whereby when each processor completes a process, information relating to the process is stored in the main memory unit and the first address of this information or the intercommunicating information is transmitted to the queue buffer from which any idle or vacant processor reads out the intercommunicating information. The queue buffer accompanies an intercommunicating information read/write control unit which controls the transmission and reception of intercommunicating information between the processors and the queue buffer. In this way, intercommunicating processing is accomplished without requiring any access to the main memory unit and without requiring the operation of an operating system for intercommunication. Thus, the multi-processor data processing system has a reduced burden on the main memory unit and the operating system and is efficient and economical.
