In one embodiment, a branch prediction control system is configured to move a mispredicted conditional branch from a smaller cache side that uses the lower complexity conditional branch predictor to one of the two large cache sides that uses the higher complexity conditional branch predictors. The move (write) is achieved according to a configurable probability or chance to escape misprediction recurrence and results in a reduced amount of mispredictions for the given branch instruction.
