BRANCH TARGET STORAGE AND RETRIEVAL IN AN OUT-OF-ORDER PROCESSOR

A processor configured to facilitate transfer and storage of predicted targets for control transfer instructions (CTIs). In certain embodiments, the processor may be multithreaded and support storage of predicted targets for multiple threads. In some embodiments, a CTI branch target may be stored by one element of a processor and a tag may indicate the location of the stored target. The tag may be associated with the CTI rather than associating the complete target address with the CTI. When the CTI reaches an execution stage of the processor, the tag may be used to retrieve the predicted target address. In some embodiments using a tag to retrieve a predicted target, CTI instructions from different processor threads may be interleaved without affecting retrieval of predicted targets.
