Questions tagged [apic]

The APIC units are responsible for delivering interrupts from interrupt sources to interrupt destinations throughout the multiprocessor system.

The Advanced Programmable Interrupt Controller (APIC) is based on a distributed architecture in which interrupt control functions are distributed between two basic functional units, the local unit and the I/O unit. The local and I/O units communicate through a bus called the Interrupt Controller Communications (ICC) bus. The local APIC units also provide interprocessor interrupts (IPIs), which allow any processor to interrupt any other processor or set of processors.
