Abstract: This paper analyses the feasibility of the hyperblock-level prediction in hyperblock-based aggressive execution model, puts forward a multi-exit predictor which adapts to hyperblock-based execution model. It demonstrates the feasibility and prediction-depth of hyperblock-level prediction based on this model. Experimental results show that a lot of applications have a higher expected prediction-depth, suitable for aggressive execution, but they have great difference in different applications.

Key words: aggressive execution model, hyperblock-level prediction, expected prediction-depth
