A dynamic reconfigurable circuit includes multiple clusters each including a group of reconfigurable processing elements. The dynamic reconfigurable circuit is capable of dynamically changing a configuration of the clusters according to a context including a description of processing of the processing elements and of connection between the processing elements. A first cluster among the clusters includes a signal generating circuit that when an instruction to change the context is received, generates a report signal indicative of the instruction to change the context; a signal adding circuit that adds the report signal generated by the signal generating circuit to output data that is to be transmitted from the first cluster to a second cluster; and a data clearing circuit that, when output data to which a report signal generated by the second cluster is added is received, performs a clearing process of clearing the output data received.
