An ePLX unit includes a logic unit having an SRAM and a MUX, and a switch unit having an SRAM and a TG for establishing wiring connection in the logic unit. When a composite module is set in the first mode, an Add/Flag control unit uses the SRAMs as a data field and a flag field, respectively, to autonomously control the read address of each of the data field and the flag field in accordance with a control flag stored in the flag field. Furthermore, when the composite module is set in the second mode, the Add/Flag control unit writes configuration information into each of the SRAMs to reconfigure a logic circuit. Consequently, the granularity of the circuit configuration can be rendered variable, which allows improvement in flexibility when configuring a function.
