Branch Queue

In computer architecture, while branch predictions occur the branch queue[1] stores data, specifically when the branch predictor predicts if the branch is taken or not, the branch queue stores the predictions to be used later.

A branch queue consists of only two values: taken or not taken.

A branch queue helps other algorithms to increase parallelism and optimization. It is not software implemented or hardware one; it falls under hardware software co-design.
