1. A dynamic reconfiguration supporting method that generates a driver function to cause a dynamic reconfiguration circuit to execute a program of an application described in a predetermined language, comprising: acquiring a configuration defining file representing a configuration of a cluster of the dynamic reconfiguration circuit in execution of the process of the application; generating an address map representing an address of a processing element in the cluster on the basis of the configuration defining file; generating a driver function that associates the function and the address of the processing element which executes the function with reference to the address map, when a processing element which executes a function described in the application is allocated from the processing element; and creating a driver function file that stores the driver function, further comprising: storing the driver function file and an execution code that executes the process of the application in a predetermined memory; and replacing the address of a processing element of the execution code executed by the dynamic reconfiguration circuit with an address of a processing element of the dynamic reconfiguration circuit with reference to the driver function file stored in the predetermined memory.
