Abstract
Evolutionary methods for reducing power consumption of an electronic system are disclosed. The electronic system comprises one or more subsystems. Each of the subsystems is connected to a supply power through a programmable power limiter that limits power delivered to the subsystem. A controller initiates a power reduction procedure by reducing power limit to reach a level that the subsystem delivers minimum acceptable performances.
Claims20
A power management method for an electronic system comprising a plurality of subsystems, wherein at least one subsystem is coupled to a power supply through a power limiter, the method comprising:
- (a) sending a first control signal from a controller to the power limiter, wherein said control signal comprising a signal for setting a power limit;
- (b) operating the subsystem according to the power limit;
- (c) sending a second control signal from the controller to the subsystem;
- and
- (d) removing the power limit of said power limiter.
A power management method for an electronic system comprising a plurality of subsystems, wherein at least one subsystem is coupled to a power supply through a power limiter, wherein said subsystem further comprising performance sensors, the method comprising:
- (a) sending a first control signal from a controller to the power limiter, wherein said control signal comprising a signal for setting a power limit for said power limiter;
- (b) operating said subsystem according to said power limit;
- (c) initiating a power saving procedure by the controller, wherein said procedure further comprising establishing a new power limit that corresponds to low limits of measured performance indicators of performance sensors;
- and
- (d) operating the subsystem according to the new power limit.
A power management method for an electronic system comprising a plurality of subsystems, wherein one or more subsystems are having a power limiter between the subsystems and a power supply, the method comprising:
- (a) testing one or more subsystems and establishing a power limit for each of the power limiters, wherein said power limit corresponds to minimum accepted performances of the subsystem under a predetermined operation mode;
- (b) storing the established power limits in a file system of the controller;
- (c) sending a control signal from a controller to each of the power limiters, wherein said control signal comprising a signal for setting the power limit for the power limiter;
- and
- (d) operating each of the subsystems according to each of the power limits.
