ELECTRONIC APPARATUS HAVING REDUCIBLE POWER CONSUMPTION IN THE READINESS STATE
First Claim
1. A method for managing energy consumption of an electronic device of a communications network that is controllable in at least one operating state and one standby state comprising:
- controlling the operating state with a main processing unit;
controlling the standby state with a preprocessing unit, wherein the preprocessing unit the main processing unit and at least one functional unit of the electronic device are switched into at least one state having reduced energy consumption;
monitoring input/activation/communications network interface units by the preprocessing unit when in the standby state; and
upon determining an indication for the need to change over to the operating state on one of the input/activation/communications network interface units, the main processing unit and the functional units of the electronic device, switching from a state having low energy consumption into a state not having low energy consumption.

Abstract
Method for an electronic device (IT) that is controllable in at least one operating state (OP) and one standby state (SBY), with which a main processing unit (MPU) controls the operating state (OP) and a preprocessing unit (PPU) controls the standby state (SBY), such that, by means of the preprocessing unit (PPU), the main processing unit (MPU) and, to some extent, the functional units of the electronic device (IT) that are implemented by circuitry are switched by the control into at least one state having reduced energy consumption. An advantage can be seen in the fact that, by using a preprocessing unit (PPU), in the operating state of “standby” (SBY) the total energy consumption of the electronic device (IT) is reduced, both due to the significantly reduced energy consumption of a preprocessor (PPE) in the preprocessing unit (PPU) and to the units (MPU) that have been switched by the control into a state having reduced energy consumption, and the electronic device can therefore be operated more economically. An additional advantage is that the reduction of the energy consumption is achieved exclusively by circuitry measures and that no implementations must be included in the programs of the electronic device (IT).

9. An electronic device comprising:
-
a plurality of functional units; a main processing unit that controls an operating state of the electronic device; a preprocessing unit that controls a standby state of the electronic device wherein when the electronic device is in a standby state, at least one of the functional units and the main processing unit are in a state having reduced energy consumption relative to their energy consumption in the operating state; and at least one unit selected from the group consisting of an input unit, activation unit and communications interface unit, said at least one unit monitored by the preprocessing unit when the device is in the standby state, said preprocessing unit able to determine that a need exists to change from said standby state to said operating state, and upon detecting such a need, switching said device from the standby state to the operating state. - View Dependent Claims (10, 11, 12, 13)
