Method and architecture for power management of an electronic device

A method comprising:

• providing one or more power islands, each power island including:
• a local storage capacitor connected between a local power grid and a local ground grid;
• and
• a functional circuit connected between said local power grid and said local ground grid;
• providing a global storage capacitor coupling a global power grid to a global ground grid, each local ground grid connected to said global ground grid;
• providing one or more switches, each switch selectively connecting said global power grid to a single and different corresponding local power grid;
• providing a power dispatch unit adapted to open and close said one or more switches;
• providing said power dispatch unit with a power island “ready for power” sensor circuit and connecting said power island “ready for power” sensor circuit between each of said one or more power islands and a power switch controller, said power switch controller adapted to independently open and close said one or more switches;
• and
• providing said power dispatch unit with a voltage sensor circuit having inputs and an output and connecting said inputs between said global power grid and said global ground grid and connecting said output to said power switch controller.

A method comprising:

• receiving one or more requests for power, each of said one or more requests for power from a single power island of one or more power islands, each power island including a local storage capacitor connected between a local power grid and a local ground grid and a functional circuit connected between said local power grid and said local ground grid;
• dispatching power stored in a global storage capacitor to one or more of said power islands that have requested power in response to said one or more requests for power by selectively connecting a global power grid and one or more of said local power grids, said global storage capacitor connected between a global power grid and a global ground grid, each local ground grid connected to said global ground grid;
• and
• dispatching power to power islands requesting power based on predetermined rules or power distribution algorithms.
