Abstract
A method and device is disclosed for implementing dynamic power control in an electronic system implemented on an integrated circuit, which electronic system comprises at least one or several hardware units (), a hardware based power control logic () substantially implemented with logic circuits, as well as a programmable power control mode register () containing information about powered-down modes defined for said one or more hardware units. To transfer a single hardware unit () from the powered-down mode to the operational mode, the hardware unit transmits to the power control logic () a first level sensitive status signal () for transferring the hardware unit from the powered-down mode to the wake up mode, and further a second level sensitive status signal () for transferring the hardware unit from the wake up mode to the actual operating mode.
