Abstract
The present disclosure relates to a method for managing the deep sleep mode of an embedded system. In embodiments, the method includes determining a value of the electrical charge used, during a deep sleep mode of the system, for saving software-context data into a non-volatile memory of the system; determining a value of a current used, during a deep sleep mode of the system, for saving software-context data into a volatile memory of the system; determining, from the previously determined values, a threshold value defining a duration beyond which a power consumption caused by saving software-context data into the non-volatile memory is less than that into the volatile memory; saving the software-context data into the non-volatile or volatile memory according to the expected duration of deep sleep mode of the system.
