Abstract
A first power management module includes a power management interface to communicate with a power management bus and manages power states of a first device communicating with a system bus. The power management interface includes a first interface to communicate a first control signal to transition the first device from a first power state to a second power state, a second interface to communicate a second control signal to turn on or off a power supply to the first device, and a third interface to communicate a third control signal to turn on or off a clock of the first device. A second power management module manages power consumption of the first device, independently of a second device communicating with the system bus, based on the power states of the first device using one or more of the first control signal, the second control signal, and the third control signal.
