Abstract

The invention discloses a multi-power-supply management control device, system and method applied to a processor system. The device comprises an input power supply monitoring unit, a stable-voltage power supply unit, a programmable logic unit, switching power supplies and an output power supply monitoring unit, wherein the external power supply supplies power to at least two switching power supplies through the input power supply monitoring unit; the switching power supplies output more than two paths of power supply to supply power to the processor; a power supply signal output by the input power supply monitoring unit supplies the power supply for the programmable logic unit through the stable-voltage power supply unit; the input power supply monitoring unit monitors a power supply state input by the outside; the output power supply monitoring unit monitors the power supply output by the switching power supplies; and the programmable logic unit receives the switching power supplies and controls the switching power supplies according to the state information of the input power supply monitoring unit, the output power supply monitoring unit and the switching power supplies. The problem of the power supply time sequence control during multi-power-supply management in a traditional processor system can be solved, and the power-on and power-down time sequences of various power supplies can be guaranteed to meet requirements.

Description

technical field [0001] The present invention relates to a power management device, system and method, in particular to a power management control device, system and method applied to a multiprocessor system. Background technique [0002] At present, in the existing technology, the form of the digital power management architecture mainly includes the PMIC architecture, and the PMIC architecture adopts the I 2 The C / SMBus (System Management Bus, short for System Management Bus) interface directly manages each power rail to achieve efficient management and high integration. Another form of architecture adopts the 2 A dedicated digital power supply product with C / SMBus interface, the system main control IC manages each discrete power supply rail through the bus. [0003] The first type of architecture, due to the limitations of the PMIC product itself, although its reliability and power density are very good, but its adaptability is poor, and it is only suitable for some speci...
