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.
[edit] APIC-free zone
The APIC just like it's ancestor is infamous for being a problematic bit of silicon. If fortunately has no relevance for MIPS systems as MIPS systems don't use it - even though it may be physically present in some systems.
