Branch prediction breaks instructions down into predicates, similar to predicate logic. A CPU using branch prediction only executes statements if a predicate is true.
One example is using conditional logic. Since unnecessary code is not executed, the processor can work much more efficiently.

The first time a conditional operation is seen, the branch predictor does not have much information to use as the basis of a guess.
But the more frequently the same operation is used, the more accurate its guess can become. Home Dictionary B - Definitions. Was this page useful?
