branch prediction

RU: branch prediction (предсказание ветвлений)

Branch prediction is a CPU mechanism that guesses the outcome of a conditional branch before it is evaluated and begins executing along the predicted path speculatively. Without it, a deeply pipelined processor would stall every branch waiting for the condition to resolve. Modern predictors use dynamic history tables and achieve high accuracy on regular patterns such as loop conditions, allowing the pipeline to run at near-full throughput.
