A first node apparatus includes: ports; a storage device; and receiving, updating, and transmitting circuits. The storage device stores: information associating, with first identification information identifying a first frame, information distinguishing a first port having been used as a destination port when the first node apparatus has transmitted the first frame; and information associating, with each node apparatus, state information indicating whether frame transmission from each port is feasible. The receiving circuit receives, from a second node apparatus, a second frame including second identification information. When the second identification information is identical with the first, the updating circuit updates the state information associated with a node apparatus being a destination of the second frame to make the state information indicate frame transmission from the first port is not feasible. The transmitting circuit selects a second port from which transmission of the second frame is feasible, and transmits the second frame.

Node apparatus and communication method

A reconfigurable circuit is provided, which includes a first arithmetic unit that performs addition or subtraction of a first input data and a second input data and outputs output data, and a first selector that selects an output data of the first arithmetic unit or a third input data and outputs the selected one as the first input data to the first arithmetic unit.

Reconfigurable circuit

The present invention provides a programmable logic device including a main circuit unit capable of variably building desired user logic, based on configuration data inputted from a storage device, and a configuration data monitor unit for monitoring configuration data stored in the storage device.
