Abstract:
1. An information processing apparatus comprising: a nonvolatile memory configured to store a system program for generating a power-down signal generation command in response to reception of a sleep state transition request from an operating system and for generating a sleep state transition command after generating the power-down signal generation command; a processor configured to execute the operating system and the system program; a controller connected to a peripheral device via a bus comprising at least a data line and a reset signal line, and configured to reset the peripheral device in response to reception of the sleep state transition command, and to output a sleep state transition request signal after resetting the peripheral device; and a power management module configured to set a power-down signal to the peripheral device in an active state in response to reception of the power-down signal generation command, and to set the information processing apparatus in the sleep state in response to reception of the sleep state transition request signal from the controller.
