Electronic device and method determining a workload of an electronic device |
摘要 |
An electronic device is provided with at least one functional unit (HB) performing a processing, wherein the functional unit (HB) receives a supply current (Isupply). A supply current monitor (SCM) is provided for monitoring the supply current (Isupply) to determine an average supply current (Iavg). A characterization unit (CU) is provided for determining a first relation between the averaged supply current (Iavg) and an operation frequency of the functional unit and/or for determining a second relation between a workload of the functional unit (HB) and the average supply current (Iavg) of the functional unit (HB). Furthermore, a slope calculation unit (SCU) is provided for determining the slope of the first and/or second relation. The operation of the functional unit (HB) is controlled according to the results of the slope calculation unit (SCU). |
