Power Management Unit - A simplified explanation of the abstract

  • This abstract for appeared for US patent application number 18307508 Titled 'Power Management Unit'

Simplified Explanation

The abstract describes a power management subsystem in a computer system. This subsystem includes a host device and a group of power circuits arranged in a tree-like structure. Each power circuit has its resources mapped to specific addresses in a common address space. The host device sends commands to a branch power circuit via a communication bus, and this branch power circuit relays the commands to other power circuits based on the specified power resources in the commands.


Original Abstract Submitted

A power management subsystem included in a computer system may include a host device and a power circuit group. The power circuit group includes multiple power circuits arranged in a tree-like structure. The resources of the multiple power circuits are mapped to corresponding addresses within a common address space. The host device sends, via a first communication bus, commands to a branch power circuit of the multiple power circuits, which, in turn, relays the commands, using a second communication bus, to corresponding ones of the other power circuits based on respective power resources specified in the commands received from the host device.
