Abstract

A method and apparatus for storing and classifying packets transmitted over a network to a processor in a low power mode. The processor receives and classifies the packets as interesting or not interesting. Uninteresting packets are discarded while interesting packets are stored in memory. For the first interesting packet received, a receive timer is activated and for every interesting packet received a counter is incremented. A transmit timer is activated when the processor enters the low power mode. When either the receive timer expires, the transmit timer expires or the counter reaches a threshold value then a wake-up interrupt is asserted.
