摘要Value prediction, a technique to break data dependency, is important in enhancing instruction-level
parallelism and processor performance. A new value predictor utilizing both the loop and locality properties of data
values has been proposed in this paper to pursue desirable prediction accuracy at reasonable cost. The proposed
value predictor, called the Dynamic Loop and Locality-based (DLL) predictor, makes predictions by dynamically
practicing the loop or locality-based prediction policy according to the state. With certain simple designs, the DLL
predictor gains prediction accuracy in an efficient way. To secure more comprehensive experimental evaluation
of value predictors, a new performance measure, accuracy improvement per cost, briefed as the A/C ratio, is
introduced in the paper. Simulation results show that, compared with other existing value predictors, the proposed
DLL predictor produces better A/C ratios in almost all situations due to flexible application of different prediction
policies and reduced cost.
