Webbranch prediction strategies are: 1) One-bit branch prediction buffer: In this prediction mechanism, if one assumption goes wrong branch predictor changes its prediction. i.e if a branch instruction is predicted as taken but actually the instruction is not taken, then next time predictor hardware assumes the instruction to be no taken. WebIn computer architecture, a branch predictor is a digital circuit that tries to guess which way a branch (e.g., an if–then–else structure) will go before this is known definitively.The …
