ABSTRACT:
A reconfigurable integrated circuit device, in which an arbitrary operating state is constructed based on configuration data, has a reconfigurable circuit unit, having a plurality of reconfigurable processor elements and a processor element network to connect the processor elements in an arbitrary state, and a reconfiguration control portion, which supplies configuration data to the processor elements and processor element network, to construct an arbitrary state in the reconfigurable circuit unit. In response to an external reset cancellation signal at the time power is turned on, at least a portion of the reconfigurable circuit unit is configured in a state of an initialization circuit, and in response to an internal reset cancellation circuit after completion of operation of the initialization circuit, the configuration control portion starts supplying the configuration data.
