Digital component power savings in a host device and method

A device comprising:

• means to provide a voltage;
• means to monitor a host interface to detect any one of a plurality of different commands directed to the device, the detecting based, at least in part, on a type of the command;
• and
• means to generate an awake signal, wherein generating the awake signal:
• is in direct response to detecting one of the plurality of different commands directed to the device, and
• is, once one of the plurality of different commands directed to the device is detected, without reference to additional branching logic;
• wherein the means to provide a voltage is:
• coupled to the means to monitor a host interface;
• configured to change from a first state to a second state upon receiving the awake signal;
• and
• operably coupled to a core logic section and configured to provide a supply voltage to the core logic section when the means to provide a voltage is changed to the second state.

A method comprising:

• detecting, in a host interface and based, at least in part, on a type of a detected command, any one of a plurality of different commands directed to a device;
• sending, to a voltage regulator, an awake signal:
• wherein the awake signal:
• is in direct response to the detecting one or more of the plurality of different commands directed to the device, and
• is, once one of the plurality of different commands directed to the device is detected, initiated without reference to additional branching logic;
• changing the voltage regulator from a first state to a second state, the changing in response to receiving the awake signal, wherein the voltage regulator is operably coupled to one or more components of the device;
• and
• providing, from the voltage regulator when the voltage regulator is changed to the second state, a supply voltage to the one or more components.

A hardware component containing logic configured to cause a computing system to perform operations comprising:

• controlling a signal generator to send an awake signal to a voltage regulator, wherein the controlling is performed:
• in direct response to the received indication of a detection of the one of the plurality of different commands directed to the computing device, and
• once one of the plurality of different commands directed to the device is detected, performed without reference to additional branching logic;
• and
• changing the voltage regulator from a first state to a second state, the changing in response to receiving the awake signal.
