Claim:
1. A voltage-adjusting device for adjusting voltages of one or more power domains in a chip, comprising: a distributing system including a detecting module, a forecasting module, and a distributing module, and a voltage-adjusting system, wherein: the distributing system obtains a task information for the one or more power domains, the forecasting module obtains a forecasted voltage for the power domain based on the task information, the detecting module obtains a detected voltage for a power domain, and the distributing module obtains a control signal for the power domain for controlling a voltage applied on the power domain based on the forecasted voltage and the detected voltage, the forecasted voltage being a voltage required for the power domain to execute a task; and the voltage-adjusting system, connected to the distributing system and the one or more power domains, adjusts the voltage applied on the power domain based on the control signal such that the detected voltage reaches the forecasted voltage when the power domain executes a task.
