Abstract: An example computer system includes at least two processors, a power supply controller, configuration registers, and a wake-up circuit. The computer system has a deep sleep mode in which the processors are not supplied with power. The power supply controller is configured to detect events of different types to be processed in the processors in the deep sleep mode. The configuration registers are configured to assign the processing to the different processors according to the type of event detected. The wake-up circuit is configured to disable deep sleep mode after an event is detected, and activate, when disabling deep sleep mode, a power supply of one of the at least two processor to which the processing of the detected event has been assigned according to the configuration registers. The activation of the power supply powering on one of the processors, which is configured to process the detected event.
