| Zusammenfassung: | Embodiments related to selecting a runahead poison policy from a plurality of runahead poison policies during microprocessor operation are provided. The example method includes causing the microprocessor to enter runahead upon detection of a runahead event and implementing a first runahead poison policy selected from a plurality of runahead poison policies operative to manage runahead poison injection during runahead. The example method also includes during microprocessor operation, selecting a second runahead poison policy operative to manage runahead poison injection differently from the first runahead poison policy. |
