一种支持Superscalar-VLIW混合架构处理器的混合分支预测设计
A DESIGN OF HYBRID BRANCH PREDICTOR SUPPORTING SUPERSCALAR-VLIW HYBRID MICROPROCESSOR
摘要
Abstract
A design of hybrid branch predictor on a digital signal processor which supports Superscalar-VLIW hybrid architecture is described.To control hardware complexity and improve the accuracy of prediction,a hybrid branch predictor of bimodal and PAp is selected for the branch prediction scheme.The standard DSPstone programs have been run on the processor.The experimental results show that the processor with hybrid branch predictor has an improvement of 23％ on average compared with processor without branch predictor,and processor with hybrid branch predictor predicts more accurately than processor with only bimodal predictor.关键词
