Abstract: In a networking system including a plurality of nodes connected with each other by a communication network, each node includes an abnormality discrimination unit configured, when a cumulative consumption current at the time of processing the data received from other node is out of a range (of current values estimated in advance based on an event at the other node, to discriminate the other node as an abnormal. By the networking system, the abnormality of the nodes on the network may be detected with a simple configuration.

Abstract: The present invention is provided with: a data-driven processor comprising at least a firing control which determines whether or not firing conditions have been met by determining whether or not all packets necessary for instruction execution have been received when a packet that convey a part of partitioned data to be processed has been input, and a data processing unit for performing processing corresponding to the packets transmitted from the firing control if the firing conditions have been met; a power supply circuit for supplying power to the data-driven processor; and overload avoidance means for refusing input of the packets to the data-driven processor, if a determination has been made that a data processing load in the data-driven processor may reach an overloaded state in which the data processing may stall, on the basis of current consumption in the data-driven processor. Accordingly, power consumption in a networking system is reduced.
