Abstract
A system includes a first device, a second device, and a main power management module. The first device is configured to communicate with a system bus. The second device is configured to communicate with the system bus. The second device includes a device power management module configured to manage power states of the second device. The main power management module is configured to manage power consumption of the second device independently of the first device by selectively supplying power and clock signals to the second device based on the power states of the second device. The main power management module and the device power management module each comprise a power handshake interface. The main power management module communicates with the device power management module via a power management bus using the power handshake interface.
