PURPOSE:To prevent disappearance of data due to the shortage of resources by monitoring the using situation of resources in a multi-processor system as a whole when the communication is carried out between processors. CONSTITUTION:The recognizing means 111-131 provided into processors 11-13 always inform the using situation of resources of their own processors with each other. When data are sent to a processor 12 from a processor 11, a data transmitting part 112 recognizes the using situation of both processors 12 and 13 via the means 111 to decide a transmitting time point and a transmitting route of data. When the processor 12 has the shortage of resources, the transmission of data is held by the processor 11 as if the processor 11 has no shortage of resources. When the processor 11 has the shortage of resources, data are sent to the processor 13 having no shortage of resources and held there. Then the data are sent to the processor 12 via a route 16 as soon as the shortage of resources of the processor 12 is solved. |
