Method for managing hibernation of an embedded system

An embedded system configured to operate in a deep sleep mode, the embedded system comprising:

• a non-volatile memory;
• a volatile memory;
• and
• a central circuit, the central circuit configured to:
• determine an electrical charge for storing software-context data in the non-volatile memory during the deep sleep mode,
• determine a current for storing the software-context data in the volatile memory of the embedded system at a first temperature during the deep sleep mode,
• determine a threshold based on the determined electrical charge and the current, the threshold defining a duration beyond which a first power consumption for storing the software-context data in the non-volatile memory is less than a second power consumption for storing the software-context data in the volatile memory,
• store the software-context data in the non-volatile memory in response to an expected duration of the deep sleep mode being greater than the threshold, and
• store the software-context data in the volatile memory in response to the expected duration being less than or equal to the threshold.

A non-transitory computer-readable media storing computer instructions, wherein the instructions, when executed by a processor, cause an embedded system to:

• determine an electrical charge for storing software-context data in a non-volatile memory of the embedded system during a deep sleep mode;
• determine a current for storing the software-context data in a volatile memory of the embedded system at a first temperature during the deep sleep mode;
• determine a threshold based on the determined electrical charge and the current, the threshold defining a duration beyond which a first power consumption for storing the software-context data in the non-volatile memory is less than a second power consumption for storing the software-context data in the volatile memory;
• store the software-context data in the non-volatile memory in response to an expected duration of the deep sleep mode being greater than the threshold;
• and
• store the software-context data in the volatile memory in response to the expected duration being less than or equal to the threshold.
