1. A method comprising: identifying a plurality of confidence measures for a plurality of outstanding conditional branch instructions along a predicted path, each of the plurality of confidence measures comprising a percentage value between zero and one hundred percent, a first of the plurality of confidence measures different from a second of the plurality of confidence measures; calculating a cumulative confidence measure based on a multiplication of the plurality of confidence measures including the first and second of the plurality of confidence measures; recalculating, after a completion of one of the plurality of outstanding conditional branch instructions, the cumulative confidence measure for a remainder of the plurality of outstanding conditional branch instructions along the predicted path; and reducing prefetching operations in response to detecting that the cumulative confidence measure is below a first threshold level.
