Abstract
An information handling system employs a processor that includes a thread priority controller. An issue unit in the processor sends branch issue information to the thread priority controller when a branch instruction of an instruction thread issues. In one embodiment, if the branch issue information indicates low confidence in a branch prediction for the branch instruction, the thread priority controller speculatively increases or boosts the priority of the instruction thread containing this low confidence branch instruction. In the manner, should a branch redirect actually occur due to a mispredict, a fetcher is ready to access a redirect address in a memory array sooner than would otherwise be possible.
