Abstract
A compiler includes a branch statistics data analyzer to analyze branch statistics data of a branch instruction to construct a branch predictor function for the branch instruction. A branch prediction instruction generator is coupled to the branch statistics data analyzer to generate at least one prediction instruction to implement the branch predictor function. A main compiling engine is coupled to the branch prediction instruction generator to insert the prediction instruction before the branch instruction. A method of dynamically predicting a branch instruction of a program is also described.
