PROBLEM TO BE SOLVED: To provide information related to a fault that is fatal in an electronic apparatus without reducing processing efficiency of a memory access instruction, when the fatal fault is generated and even when a CPU is executing an instruction that has no relation (asynchronization) with the fault.SOLUTION: An instruction execution unit 103 executes an access preparation instruction 108 storing a first physical address, generates a second address so that a first address read out from a program counter has the same address as an address in which an access instruction 110 is stored, generates a second physical address on the basis of the first physical address and the second address, executes a plurality of instructions 109 for replacing the first physical address stored in a resister 102 with the second physical address by storing the second physical address in the register, and executes the access instruction. The second control unit 106 notifies the outside of the second physical address when an accessed address has a fault. |
