A Mobile Platform and a Method Therein

摘要

A method for controlling powering of a mobile platform 201 comprising a first Finite State Machine (FSM) 202 and a second FSM 203. The method comprises synchronizing the first FSM with the second FSM, wherein the first FSM is arranged on a first Integrated Circuit (IC) 207 comprised in the mobile platform and configured to control a first Power Management Unit (PMU) 205 arranged on the first IC, and wherein the second FSM is arranged on a second IC 208 comprised in the mobile platform and configured to control a second PMU 206 arranged on the second IC, whereby the first PMU and the second PMU are synchronized to operate simultaneously during rank-up and rank-down, thereby providing power control of the mobile platform.

1. A method for controlling powering of a mobile platform comprising a first Finite State Machine, and a second Finite State Machine wherein the first Finite State Machine is arranged on a first Integrated Circuit comprised in the mobile platform and configured to control a first Power Management Unit arranged on the first Integrated Circuit, and wherein the second Finite State Machine is arranged on a second Integrated Circuit comprised in the mobile platform and configured to control a second Power Management Unit arranged on the second Integrated Circuit, wherein the Power Management Units have a physical connector used for a two way communication between the Power Management Units, the physical connector providing information of the various phases of the Finite State Machines, wherein the method comprises:
synchronizing the first Finite State Machine with the second Finite State Machine, whereby the first Power Management Unit and the second Power Management Unit are synchronized to operate simultaneously during rank-up and rank-down, thereby providing power control of the mobile platform.
