Abstract
Embodiments of the invention provide a method of storing branch prediction information. In one embodiment, the method includes receiving a branch instruction and storing local branch prediction information for the branch instruction including a local predictability value for the local branch prediction information. The method further includes storing global branch prediction information for the branch instruction only if the local predictability value is below a threshold value of predictability.
