Estimating utilization of an electronic system component

摘要

Method and apparatus for estimating utilization of an electronic system component. Trace information that includes start times and completion times of operations resulting in access to the system component is gathered for a period of time. Using the start times and completion times of the trace information a total of time expended by the operations is generated. A component-occupancy value that indicates a ratio of the total time to the length of the period of time is then generated to indicate the occupancy of the component.
