Intel® 64 Architecture x2APIC Specification

This document describes the x2APIC architecture which is extended from the xAPIC architecture. Extensions to the xAPIC architecture are intended primarily to increase processor addressability. The x2APIC architecture provides backward compatibility to the xAPIC architecture and forward extendability for future Intel platform innovations.
