PROBLEM TO BE SOLVED: To provide an information processing device and the like capable of switching an access method at high speed to perform access control to a device configured to be accessible by a plurality of access methods.SOLUTION: The information processing device 10 includes a first processing part 100 asserting a first chip select signal SC1 or a second chip select signal CS2 according to an address space to be accessed, and a second processing part 200 configured to be accessible from the first processing part 100 by a first or second access method. When the first chip select signal SC1 is asserted, the first processing part 100 accesses the second processing part 200 by the first access method, and when the second chip select signal CS2 is asserted, the first processing part 100 accesses the second processing part 200 by the second access method. |
