1. A circuit design information generating equipment, comprising: a first memory area that stores a source program which corresponds to at least one basic function of a plurality of functions; a second memory area that associates circuit design information used to reconfigure a circuit with the basic function and stores circuit design information; and a control component that, when the basic function constitutes a requested function, and the circuit design information that corresponds to the basic function is stored in the second memory area, reconfigures the circuit using the stored circuit design information, and when the circuit design information that corresponds to the basic function is not stored in the second memory area, generates circuit design information corresponding to the basic function using the source program corresponding to the basic function stored in the first memory area, stores the generated circuit design information in the second memory area, reconfigures the circuit configured to execute the requested function using the generated circuit design information, and executes the requested function with the reconfigurable circuit.
