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 design information with the basic function and stores the circuit design information; and a control component that, when the basic function of the plurality of functions constitutes a requested function, and circuit design information that corresponds to the basic function is stored in the second memory area, uses the stored circuit design information, and, when the circuit design information that corresponds to the basic function of the plurality of functions is not stored in the second memory area, uses the source program corresponding to the basic function of the plurality of functions stored in the first memory area, and performs control so as to generate circuit design information corresponding to the basic function of the plurality of functions and stores the generated circuit design information in the second memory area, and, using the generated circuit design information, reconfigures a circuit design information configured to execute the requested function, and executes the requested function with the reconfigurable circuit design information.
