ELECTRONIC DEVICE AND METHOD OF PERFORMING A POWER MANAGEMENT IN AN ELECTRONIC DEVICE

摘要

An electronic device is provided which comprises at least one functional unit (HB) for performing a processing. The functional unit (HB) receives a supply current (Isupply). The electronic device furthermore comprises a supply current monitor (SCM) for monitoring the supply current (Isupply) in order to determine an average supply current (Iavg). The electronic device furthermore comprises a characterization unit (CU) for determining a relation between the average supply current (Iavg) and an operating frequency of the functional unit. Furthermore, a slope calculation unit (SCU) is provided to determine the slope of the relation. Moreover, a power management unit (PMU) is provided to control the operation of the functional unit (HB) according to the results of the slope calculation unit (SCU) in order to control the power dissipation of the functional unit (HB).
