Abstract: 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.

Abstract: A current measurement circuit is disclosed. The current measurement circuit includes first and second circuit branches coupled to a circuit node through which current is to be measured. During a first period, the first circuit branch converts the current into a first voltage. During a second period, the second circuit branch converter the current into a second voltage. An analog-to-digital converter is configured to convert the first and second voltages into digital values indicative of the measured current. A control circuit is configured to alternately select one of the first and second branches during the generation of the digital values.
