METHODS, SYSTEMS AND APPARATUS FOR SUPPORTING WIDE AND EFFICIENT FRONT-END OPERATION WITH GUEST-ARCHITECTURE EMULATION

摘要

Methods for supporting wide and efficient front-end operation with guest architecture emulation are disclosed. As a part of a method for supporting wide and efficient front-end operation, upon receiving a request to fetch a first far taken branch instruction, a cache line that includes the first far taken branch instruction, a next cache line and a cache line located at the target of the first far taken branch instruction is read. Based on information that is accessed from a data table, the cache line and either the next cache line or the cache line located at the target is fetched in a single cycle.

1. A method for supporting wide and efficient front-end operation with guest architecture emulation, comprising:
upon receiving a request to fetch a first far taken branch instruction of a first cache line, reading said first cache line, a next cache line and a cache line at a target of said first far taken branch instruction; and fetching based on information accessed from a data table, said first cache line and one of said next cache line and said cache line at said target of said first far taken branch instruction in a single cycle.
