A method of waking up components in a dual-processor based system comprising a first processor system (310) to be activated. Upon activation, components in a second processor system (320) need to be activated. The method comprises initiating a wake-up process (405) and waking-up first processor system components, and generating an interrupt signal (420). The interrupt signal is used to wake-up second processor system components that are required to be woken for the wake-up process of the first processor system (310). The second processor system components are activated at, or before, a time when the first processor system requires the components to be activated. A dual processor based system is also described. In this manner, components used in a second processor system are awoken in a timely manner when they are needed in the awakening process of the first processor system. This prevents delay and reduces power consumption in a device. |
