Abstract
Official abstract text for this publication.
Techniques pertaining to analyzing power consumed by a processing unit in a mobile computing device caused by execution of certain modules are described herein. A power trace is generated that indicates an amount of power consumed by the processing unit over time, and the power trace is aligned with an execution log. Spikes are extracted from the power trace, and computing operations are performed over the spikes to acquire data pertaining to power consumed by the processing unit that are attributable to modules in the execution log.
First claim
Opening claim text (preview).
What is claimed is: 1. A method, comprising: accessing a spike that is retained in a data repository, the spike being time-series data over a defined window of time, the spike comprising: an amount of electric power utilized by a processing unit in a mobile computing device with a particular hardware configuration at a plurality of time intervals in the window of time; and identities of modules executed by the processing unit in the mobile computing device within the defined wi…
