System and method for dynamically adjusting host low power clock frequency without depending on peripheral low power clock frequency

Abstract

This disclosure relates generally to a host-peripheral interface, and more particularly to system and method for dynamically adjusting a low power clock frequency of a host device upon detecting coupling of a peripheral device to the host device. In one embodiment, a method is provided for dynamically adjusting a low power clock frequency of a host device. The method comprises dynamically determining an initial frequency of a low power clock of the host device at which a low power link between the host device and a peripheral device is operational, computing a low power clock frequency range of the host device based on the initial frequency of the low power clock, assessing the low power link in the low power clock frequency range, and adjusting the low power clock frequency to a typical frequency of the low power clock frequency range based on the assessment.
