1.1.6. IEM software

The IEM software component, uses information from the Operating System (OS) to build up a historical view of the execution of the application software running on the system.

A number of different software algorithms are applied to classify the types of activity and to analyze their processor utilization patterns. The results of each analysis are combined to make a global prediction about the future performance requirement for the system. This prediction is used by the IEC.

The IEC hardware component works in close association with the IEM software component. The IEM software is a separate, licensable product available from ARM and is not described in this document.
