Abstract

A multiplexer selects one of a plurality of sense outputs from sensing circuits. Each of the sensing circuits is located in a corresponding one of voltage regulators supplying power to processors in a subsystem. The corresponding one of voltage regulators is associated with one of processors. An analog to digital converter converts the selected one of the plurality of sense outputs to a digital parameter representing energy consumption of the one of the processors associated with the corresponding one of the voltage regulators. The energy consumption is used for dispatching a dynamically generated code.
