METHOD FOR SWITCHING BETWEEN INTERPRETATION AND DYNAMIC TRANSLATION IN A PROCESSOR SYSTEM BASED UPON CODE SEQUENCE EXECUTION COUNTS

A method for executing a target application on a host processor including the steps of translating each target instruction being to be executed into host instructions, storing the translated host instructions, executing the translated host instructions, responding to an exception during execution of a translated instruction by rolling back to a point in execution at which correct state of a target processor is known, and interpreting each target instruction in order from the point in execution at which correct state of a target processor is known.
