摘要
A processor comprising a processor pipeline comprising one or more execution units configured to execute branch instructions, a branch predictor associated with the processor pipeline and configured to predict a branch instruction prediction outcome, and the branch prediction unit. The branch predictor is turned off to save power and avoid miss-predictions when the branch predictor and/or branch prediction unit accuracy is lower than expected.
