DISTRIBUTED POWER MANAGEMENT

摘要

A power management bus (12) for controlling power over multiple device subsystems includes a master power bus controller which transmits power management information to control one or more power resources through a transmit interface (26). The transmitted information is received at one or more receive interfaces (28). A broadcast message can be transmitted to control multiple power resources by subsystem, resource group and resource type. A single address message can be transmitted to control a single power resource (34). A power down can be initiated at any of the receive interfaces.
