Abstract: A Power Management Controller (PMC) which manages power states of a platform, informs a power accumulator device to start measuring the platform power during entry into the low power state (e.g., S0iX). The power accumulator device starts measuring the power until a stop message comes from the PMC. The PMC on detection of any wake event initiates a stop message to the power accumulator device. Once an operating system (OS) context is restored, software can read the measured data from the power accumulator device. The measured data is accessible to a host software using standard software application programming interface (API) and can be used to influence the power policies of the system.

Abstract: In some embodiments, power may be temporarily removed from a first portion of a computer system (such as a display), and that power redirected to a second portion (such as a processor or System on a Chip), so that extra performance may be obtained from the second portion without exceeding the power budget for the system. If the first portion is a display, the time period of removed power may be short enough that the absence of luminance during that time period will not be noticeable to the human vision system. In a similar embodiment, power may be delivered to the first portion using pulse width modulation, using the time between pulses to redirect power to the other portion.
