摘要
A microprocessor (100) may include a retire queue (102) and one or more data speculation verification units. The data speculation verification units are each configured to verify data speculation performed on operations. Each data speculation verification unit generates a respective speculation pointer identifying outstanding operations on which data speculation has been verified by that data speculation verification unit. The retire queue (102) is configured to selectively retire operations dependent on the speculation pointer received from each of the data speculation verification units.
