Abstract

Apparatuses and methods are disclosed for implementing an inter-processor communication channel including power-down functionality. In one embodiment, the apparatus may comprise a first integrated circuit (IC), a second IC coupled to the first IC via a communication interface, wherein the first IC is in one or more low power states and unable to monitor the communication interface. The apparatus may further comprise an inter-processor communication (IPC) channel coupled between the first and second ICs, wherein the IPC channel is separate from the communication interface and wherein the second IC generates at least one advisory signal to the first IC via the IPC channel.
