Реферат: A method of waking up components in a dual-processor based system. The system includes a first processor system to be activated. Upon activation, components in a second processor based system are required to be likewise activated. The method comprises initiating a wake-up process of a first processor system, waking-up the first processor system components, and generating an interrupt signal. The interrupt signal is passed to the second processor system to initiate a wake-up process of the second processor system components that are required to be woken for the wake-up process of the first processor system. This is performed such that the second processor system components are activated at, or before, a time when the first processor system requires second processor system components to be activated. A dual processor based system is also described. In this manner, components used in a second processor system, for example a man machine processor system, are awoken in a timely manner when they are needed in the awakening process of the first processor system, for example a GSM processor system to facilitate the periodic scanning of a GSM control channel or timeslots. This prevents delay and reduces power consumption.
