Methods and devices for reducing power consumption in a multi-processor computing device include filtering indications from the second processor intended for the first processor while the first processor is in a low power state, so that only selected, such as significant, indications are transmitted. The second processor may be informed when the first processor is in a low power state. Indications generated by the second processor may be compared to indication filtering criteria to determine whether each should be transmitted to the first processor. Those indications satisfying the indication filtering criteria may be sent to the first processor, causing it to return to a normal power state. In mobile computing device the first processor may be an applications processor and the second processor may be a modem. Filtering of indications may be accomplished in the second processor or in a power controller in some implementations.
