<P>PROBLEM TO BE SOLVED: To provide an information processing apparatus capable of preventing unauthorized access to unused functions within an integrated circuit device, and of performing routing control for an optimum processing unit that performs an interruption process. <P>SOLUTION: The information processing apparatus has a plurality of function means assigned according to a characteristic memory map, and a plurality of interface means corresponding to the respective function means and each adapted for converting an address inputted in access to the corresponding function means into the address of a memory map common to all the function means. The interface means is provided with an address conversion means for storing address conversion information such that the address of the common memory map corresponding to the address inputted is associated with accessibility information indicating whether or not the address can be accessed, and for converting the address inputted into the address of the common memory map according to the address conversion information. The address conversion means is provided with an unauthorized access processing means for determining whether or not it is possible to perform address conversion for the address inputted, and, if it is determined to be not possible, determining the access as unauthorized, and performing a corresponding process. <P>COPYRIGHT: (C)2010,JPO&INPIT |
