Assignee: CYPRESS SEMICONDUCTOR CORPORATION
Field: Computer technology (Electrical engineering)
Classification: CPC G  Y | IPC G

Claim 16:
17. A method of determining an energy consumption of components of an integrated circuit (IC) device, the method comprising:
receiving, by an energy estimating circuit, first activity signals indicative of first bus activities by a first component of the IC device, wherein the first activity signals represent a number of event activities by the first component;
receiving, by the energy estimating circuit, second activity signals indicative of second bus activities by a second component of the IC device, wherein the second activity signals represent an amount of time the second component is active;
determining, by the energy estimating circuit, a first estimate of energy consumption by the first component based on the number and a first coefficient representing an average amount of energy consumed for a given event activity;
determining, by the energy estimating circuit, a second estimate of energy consumption by the second component based on the amount of time the second component is active and a second coefficient representing an average amount of energy consumed for a given duration activity; and
adjust an operational setting of the IC device based on the first estimate and the second estimate.
