Executing programs for a first computer architecture on a computer of a second architecture

摘要

A method for transferring execution from a first computer instruction stream to a second computer instruction stream, comprising:
profiling the first computer instruction stream, wherein the profiling includes recording details of the execution flow of the first computer instruction stream to create a profile of the first computer instruction stream;
analyzing the profile of the first computer instruction stream to identify a frequently executed section;
translating the frequently executed section of the first computer instruction stream into the second computer instruction stream;
monitoring execution of the first computer instruction stream to determine when execution has reached the frequently executed section;
transferring execution from the first computer instruction stream to the second computer instruction stream to execute the frequently executed section; and
returning execution to the first computer instruction stream when execution of the frequently executed section is complete.
