Power estimation
A device for power estimation is disclosed. The device includes a transformer circuit coupled with a processing circuit and a transaction interface. The transformer circuit is configured to count performance activities executed in the processing circuit and to compare count values of the performance activities with a predetermined value to determine a power state of the processing circuit. The transaction interface is configured to receive a request from the processing circuit and record a first timestamp, and further configured to receive a response from a memory model and record a second timestamp, the transaction interface being further configured to record a time difference between the first timestamp and the second timestamp as a time difference. The transformer circuit is further configured to determine the power state of the processing circuit based on both of the count values and the time difference.
