Power Aware Interrupt Routing (PAIR)

The processor includes enhanced power-performance technology that routes interrupts to threads or processor IA cores based on their sleep states. As an example, for energy savings, it routes the interrupt to the active processor IA cores without waking the deep idle processor IA cores. For performance, it routes the interrupt to the idle (C1) processor IA cores without interrupting the already heavily loaded processor IA cores. This enhancement is most beneficial for high-interrupt scenarios like Gigabit LAN, WLAN peripherals, etc.
