Abstract
A method for improving an accuracy of a loop branch prediction algorithm by a bypass circuit, comprising: adding a bypass circuit to a loop branch prediction algorithm; and for three pcs entering a pipeline, enabling pc1 fetched in an if0 stage to enter a hybrid branch predictor, and registering pc1; obtaining branch prediction information in an if1 stage, and making a comparison in an if2 stage to obtain a prediction result, registering the prediction result obtained in the if2 stage, and processing pc2 and pc3 in a same way.
