Abstract: The information processing device includes a CPU, DRAM, SRAM and hibernation circuitry. The hibernation circuit executes an evacuation processing of reading out particular data which is data stored in DRAM and storing the particular data in SRAM when a predetermined execution condition for hibernation is satisfied. CPU shuts off the electric power supply to DRAM while maintaining the electric power supply to SRAM after the evacuation processing is completed. When startup, CPU reads out the particular data stored in SRAM when the particular data is stored in SRAM.

Abstract: An unprotected area of a storage stores a monitoring application. A protected area of the storage stores a duplicate application that is a copy of the monitoring application at a point in time when the monitoring application was stored in the unprotected area. Based on an execution signal of the monitoring application, a CPU stores, as first data in a RAM, a copy of a source code included in the monitoring application. The CPU also executes the monitoring application based on the first data. Based on the execution signal, the CPU stores, as second data in the RAM, the copy of the source code included in the duplicate application. During execution of the monitoring application, the CPU stops execution of the monitoring application when a discrepancy is detected between the first data and the second data.

Abstract: When a request for storing a new application is received in the first storage unit, a new application is downloaded and the new application is stored in the first storage unit, a maximum usage amount of the second storage unit used in association with the execution of the new application is calculated, and when the calculated maximum usage amount is larger than the set value, the new application is erased from the first storage unit, and when the calculated maximum usage amount is equal to or smaller than the set value, the new application is put into an executable state without being erased from the first storage unit.
