Description
technical field [0001] The invention relates to the technical field of power management, in particular to a processor multi-power management control device, system and method. Background technique [0002] A multi-processor or multi-core processor system usually includes multiple functional chips, and the power supply voltage and power supply time of each functional chip may be different, so it is necessary to manage and control the multiple power supply sources. [0003] In the prior art, the power management chip is usually connected to each power supply respectively, and each power supply is controlled through the power management chip, so as to achieve the purpose of managing each power supply. However, in the prior art, the power-on sequence of each power supply is only managed through the power management chip, but in practical applications, when each power supply supplies power to each functional chip, the output voltage will be excessive due to various factors.
