Abstract
An apparatus for on-demand power management includes an I/O serial communication master device, peripheral devices that communicate with the master device along the serial bus, and a power manager that buffers the peripheral devices from the serial communication master. The power manager also manages voltage regulation and clock sources to the peripheral devices, with the ability of placing the peripheral devices in an inactive state, or in any number of active states as a means to conserve energy. In some embodiments, the I/O serial communications master acts as if the peripheral devices are always in the highest activity state, and the power manager manages the communications to and from the peripheral devices and the power management of the peripheral devices to minimize energy consumption and reduce system latency.
