PROBLEM TO BE SOLVED: To operate a high-reliability application and a low-reliability application in a mixed manner.SOLUTION: A multi-core processor system 100 is in a state where a CPU #1 executes a low-reliability application 111, and a CPU #2 executes a high-reliability application 112. A memory protection controller 106#2 accesses a high-reliability application memory region 123 within a user region 121, and accesses a high-reliability application memory region 125 within a protection region 124. When data in the high-reliability application memory region 123 is destroyed due to unauthorized writing by the low-reliability application 111, the CPU #2 restores the data by copying the data in the high-reliability application memory region 125 to the high-reliability application memory region 123. |
