Question

Explain Dynamic Branch Prediction.

Answer 1

Static Branch Prediction in general is a prediction that uses information that was gathered before the execution of the program. Dynamic Branch Prediction on the other hand uses information about taken or not taken branches gathered at run-time to predict the outcome of a branch.

Answer 2

Hyy,

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. Branch predictors play a critical role in achieving high effective performance in many modern pipelined microprocessor architectures such as x86.
