Energy management system configured to generate energy management information indicative of an energy state of processing elements

摘要

A data processing apparatus and methods are disclosed. The data processing apparatus comprises: data processing elements operable to process data; an energy management unit operable to generate energy management information indicative of an energy state of at least one of the data processing elements when processing said data; and logic operable to receive said energy management information and to generate energy management information items associating said energy state with the processing of said data. The information items can provide visibility of how the Energy State of the data processing elements vary in response to the processing of data. Providing this visibility of the Energy State can advantageously enable more detailed the energy management to be performed and the Energy State of the data processing elements to be optimized.
