Abstract

The invention provides a central manager system and a power management device thereof, and the device comprises a power module which is used for providing a working power supply for the device; the output module is connected with the power supply module and is used for converting the working power supply into different types of power supply voltage signals and respectively providing the power supply voltage signals to various types of working modules of the central processing unit; and the communication module is connected with at least part of the sub-modules in the output module and is used for receiving an instruction of the central processing unit and controlling the output voltage signals of the at least part of the sub-modules based on the instruction. According to the invention, based on the communication between the single power management device and the central processing unit, the power supply requirements of each working module in the central processing unit can be met, the power supply structure of the central processing unit is simplified, the power supply efficiency of the central processing unit is improved, the cost is greatly reduced, and the reliability and safety of the whole system are ensured.

Description

technical field [0001] The invention relates to the field of power management, more specifically to the power management of a central processing unit. Background technique [0002] At present, the central processing unit has become the most widely used hardware system architecture in the computer field. Due to its absolute position in the market share, the central processing unit developed based on it can adapt to almost all software and hardware in the field of personal hosts and servers. However, due to the inconsistency of standards in various fields and insufficient development investment in such a versatile hardware system, in its current hardware system, the integration of the power management system that supplies power to the central processing unit is very low, for example, for Every specific design requires a scattered combination of various power supplies, and even each voltage must be individually connected to the front and rear stages in order to meet the timing...
