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 (201, 202, 203), a hardware based power control logic (204) substantially implemented with logic circuits, as well as a programmable power control mode register (208) containing information about powered-down modes defined for said one or more hardware units. To transfer a single hardware unit (201, 202, 203) from the powered-down mode to the operational mode, the hardware unit transmits to the power control logic (204) a first level sensitive status signal (201a, 202a, 203a) for transferring the hardware unit from the powered-down mode to the wake up mode, and further a second level sensitive status signal (201b, 202b, 203b) for transferring the hardware unit from the wake up mode to the actual operating mode.

Abstract: The invention relates to a method for enabling in a processing system a communication between at least two activated processes 22,23. In order to improve the communication between different processes 22,23 of a processing system, it is proposed that for said communication signals are transmitted between said at least two processes 22,23 in virtual channels using the same physical channel 28. This enables an efficient use of physical resources. A corresponding processing system comprises at least one processor 50-52 for running different processes, at least one physical channel provided for enabling a communication between at least two of said different processes, and means 55-57 for distributing signals which are to be transmitted for such a communication between said at least two different processes to different virtual channels on said at least one physical channel.
