| Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a multiprocessor system that eliminates redundancy in data assurance at data communication between respective processing parts. SOLUTION: At data communication between a network processing part 101 and a real time processing part 201, exclusive control of a shared memory is executed only by an output action of an interrupt signal of transmission completion from the transmitting network processing part 101 to the receiving real time processing part 201 and a detection action of the interrupt input of transmission completion at the receiving real time processing part 201, and data assurance against data garbling and data loss is executed only by TCP/IP protocol stack software 213.
