A new value predictor utilizing both the loop and locality properties of data values is proposed in this paper to pursue desirable prediction accuracy at reasonable cost. The proposed Dynamic Loop&Locality-based (DLL) predictor makes predictions by dynamically practicing the loop or locality-based prediction policy according to the state. Aided by some simple designs, the DLL predictor proves to be effective and cost-efficient when compared with other value predictors.
