A method and system for managing computational workload in a computerized system powered by an energy source. This invention relies first and foremost on adapting computational workload at the computerized system according to a time-varying property of the power supplied by the energy source, such that power generated at the source is optimized. A feedback mechanism is accordingly implemented which changes power available for computation, e.g., to track a more efficient energy generation efficiency point at the source.

Energy capture of time-varying energy sources by varying computational workload

A washing machine driven by frequency conversion AC speed includes: a repeatedly reversible rotation washing mechanical system and a one-way rotation spinning mechanical system, a drive unit output rotation force to the washing mechanical or the spinning mechanical system, an asynchronous motor driving said drive unit and an adjustable supply with adjustable output frequency F and voltage U to supply to the asynchronous motor characterizing that the washing mechanical system can rotate reversibly and the spinning mechanical system rotates in one way the total or part of the start up process from zero to the maxium speed, the frequency F output by the adjustable supply is the increased function of time T, and voltage U is the increasing function of F.

The invention relates to a voltage and frequency adjusting device, a system chip and a voltage and frequency adjusting method. The device comprises a processing unit, at least one sensing unit and a control unit. The sensing units are electrically coupled with the processing unit and used for measuring the characteristics of at least one device of at least one logic circuit in the system chip andoutputting at least one sensing result to the processing unit. The processing unit generates a control signal according to the sensing results. The control unit receives the control signal and adjustsat least one of the operation frequency and the operation voltage of the logic circuits. In addition, the invention further provides the system chip and the voltage and frequency adjusting method.
