  1. In computer architecture, a branch predictor is the part of a processor that determines whether a conditional branch (jump) in the instruction flow of a program is likely to be taken or not. This is called branch prediction. Branch predictors are important in today's modern, superscalar processors for achieving high performance.

    What is a branch predictor?Not to be confused with Branch predication. In 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 purpose of the branch predictor is to improve the flow in the instruction pipeline.

    How does branch prediction work in a pipelined processor?Almost all pipelined processors do branch prediction of some form, because they must guess the address of the next instruction to fetch before the current instruction has been executed.

    What is the difference between binary branch and branch target prediction?Branch target prediction is not the same as branch prediction which attempts to guess whether a conditional branch will be taken or not-taken (i.e., binary). In more parallel processor designs, as the instruction cache latency grows longer and the fetch width grows wider, branch target extraction becomes a bottleneck.

    What is global branch prediction?Global branch prediction A global branch predictor does not keep a separate history record for each conditional jump. Instead it keeps a shared history of all conditional jumps. The advantage of a shared history is that any correlation between different conditional jumps is part of making the predictions.

    In computer architecture, a branch target predictor is the part of a processor that predicts the target of a taken conditional branch or an unconditional branch instruction before the target of the branch instruction is computed by the execution unit of the processor.
    Branch target prediction is not the same as branch prediction which attempts to guess whether a conditional branch will be taken or not-taken (i.e., binary).
