Abstract

Methods and apparatus relating to robust governing of power management infrastructure in a bridge design are described. In one embodiment, a first agent (such as a processor core) is coupled to a second agent (such as an input/output device) via a bridge. The bridge may or may not enter a different power management state from a current power management state based on a second derivative value. The second derivative value may be in turn determined based on a plurality of first derivative values corresponding to received packets Other embodiments are also disclosed and claimed.

First claim

The invention claimed is:

1. An apparatus comprising:
a plurality of storage devices to store a plurality of values corresponding to received packets;
first logic to determine first derivative values based on the plurality of values corresponding to the received packets; and
second logic to determine a second derivative value based on the first derivative values,

wherein a bridge is to enter a different power management state from a current power management state based on t…
