PROBLEM TO BE SOLVED: To provide a technique to enable efficient interrupt communication within a computer system.SOLUTION: An advanced programmable interrupt controller (APIC) comprises an interrupt control interface (ICI) coexisting with a legacy interrupt control interface, and is interfaced via a set of bits within an APIC interface register using various interface instructions or operations, without using memory-mapped I/O (MMIO). |
