Abstract

When generating a suspend request for a system running on an apparatus, data is stored to a non-volatile memory as a hibernation image which represents a memory state of a volatile memory, register values of a peripheral, and register values of a processor. When generating a boot request of the system, it is determined whether a valid hibernation image is available in the non-volatile memory. When the valid hibernation image is available, a boot core of the processor initializes a part of slave cores of the processor, and the boot core and/or the initialized slave core initialize the peripheral to perform a kernel initialization of the system. After the kernel initialization is completed, the memory state, and the register values of the peripheral and processor are restored based on the valid hibernation image.
