Beschreibung
Zusammenfassung:	An apparatus and method for performing high performance instruction emulation. One embodiment of the invention includes a processor to process an instruction set including high-power and standard instructions comprising: an analysis module to determine whether a number of high-power instructions within a specified window are above or below a specified threshold; an execution mode selection module to select a native execution of the high-power instructions if the number of high-power instructions are above the specified threshold or to select an emulated execution of the high-power instructions if the number of high-power instructions are below the specified threshold.
