Contributor-based power modeling of microprocessor components

摘要

A method for generating a power model for a device includes identifying a device-level set of power contributors for a given state of the device, wherein each power contributor in the device-level set of power contributors contributes to power dissipation when the device is in the given state, and generating the power model for the device based on the device-level set of power contributors, wherein the power model is independent of process, voltage, and temperature.

1. A method for generating a power model for a device, the method comprising:
identifying a device-level set of power contributors for a given state of the device that is incompletely specified, wherein each power contributor in the device-level set of power contributors contributes to power dissipation when the device is in the given state; and generating the power model for the device based on the device-level set of power contributors, wherein identifying the device-level set of power contributors for a given state of the device further comprises: determining states of a set of constituent cells of the device; determining, for each of the constituent cells, a cell-level set of power contributors that contribute to power dissipation when the constituent cells are in the states, wherein the device-level set of power contributors aggregates the cell-level set of power contributors for all of the constituent cells, the states of the constituent cells comprise, for each of the constituent cells, a plurality of states associated with a plurality of probabilities, and the states of at least some of the constituent cells are determined using a random simulation technique.
