The above listed components, which are part of the IEM system, co-operate with each other to optimize power
consumption, without compromising on performance or responsiveness.
Work flow of IEM system:
•
When the IEM software starts, software registers some kernel hooks with the OS.
•
The OS uses these kernel hooks to invoke the IEM software. It does so whenever a system event occurs that
might influence the optimum performance level.
•
The IEM software records information about the events that occur, and the related tasks.
•
The policies that are a part of the IEM software analyze this information to determine the optimum
performance level.
•
Whenever the optimum performance level changes, the IEM software uses the performance scaling hardware
to set the new level.
