A METHOD FOR EMULATING A GUEST CENTRALIZED FLAG ARCHITECTURE BY USING A NATIVE DISTRIBUTED FLAG ARCHITECTURE

摘要

A method of emulating a guest central flag architecture using a native distributed flag architecture is disclosed. The method includes receiving an incoming instruction sequence using a global front end; Grouping instructions to form instruction blocks, each instruction block comprising two half blocks; Scheduling instructions of the instruction block to execute according to a scheduler; And using the distributed flag architecture to emulate the central flag architecture for emulation of guest instruction execution.
