APIC

Advanced Programmable Interrupt Controller (I/O APIC) provides multi-processor interrupt management. This chipset will allow static and dynamic symmetric interrupt distribution across all processors. In systems with multiple I/O subsystems, each subsystem can have its own set of interrupts and every interrupt pin is individually programmable.
