Problems solved by technology

However, in terms of actual operating conditions, solid-state drives often enter sleep mode early before the idle time reaches the timeout time for the host to start power management, which affects the operating performance of the solid-state drive
[0004] As far as device startup power management is concerned, the timeout time for device startup power management is set as a fixed value by the firmware of the solid state drive, and the setting cannot be changed by the host system according to the actual operating conditions, which may easily cause management problems. Inconvenience

Embodiment Construction

[0013] The present invention determines different control parameters according to different usage states, and then utilizes the control parameters to set the idle timeout time for device startup power management of the storage device. In this way, the device startup power management settings of the storage device can be dynamically adjusted.

[0014] figure 1 is a block diagram of an electronic device according to an embodiment of the present invention.

[0015] Please refer to figure 1 , the electronic device 10 includes a processor 11 and a storage device 12 . The electronic device 10 of this embodiment may be, for example, a notebook computer, a tablet computer, a smart phone, or a multimedia device. However, the electronic device 10 can be any host system device having a processor 11 that can cooperate with the storage device 12 to store data, and the present invention does not limit the type of the electronic device. The storage device 12 can be a memory storage devic...

Abstract

The invention provides an electronic device and a power management method thereof. The electronic device comprises a storage device which supports advanced power management and device starting power management. The method comprises the following steps of: sensing a using state of the electronic device; and deciding a control parameter corresponding to the advanced power management of the storage device according to the using state. Moreover, the method comprises a step of setting an idle overtime of the device starting power management of the storage device according to the control parameter.

Description

technical field [0001] The invention relates to an electronic device and a power management method thereof, and in particular to an electronic device of a serial advanced technology accessory solid-state hard disk and a power management method thereof. Background technique [0002] At present, the power management of Solid-State Disk (SSD) using Serial Advanced Technology Attachment (SATA) interface can be mainly divided into Host Initiated Power Management (HIPM) initiated by the host side. ) and Device Initiated Power Management (DIPM) initiated by the device side. Generally speaking, solid-state drives support device power management to ensure that the solid-state drive can still operate according to its own inherent power management mechanism when there is no other power management mechanism. [0003] As far as the host starts power management, the timeout for starting the power management of the host can be set by the host-side system to control the solid state disk to...
