Device provided with rewritable circuit, updating system, updating method, updating program and integrated circuit

摘要

A problem to be solved is that a conventional device is not equipped with a unit that enables efficient circuit update taking into consideration an unconfigured area in the reconfigurable circuit in the device. A data using device of the present invention transmits, to a design data generation apparatus, device information relating to functions and structures of circuits included in the data using device, and receives design data generated by the design data generation apparatus. The data using device updates the function thereof based on the received design data. With this structure, the present invention can provide the data using device and the design data generation apparatus that are capable of managing the configuration of the circuits in the data using device, and acquiring properly the data to update the function thereof.
