| 内容記述 | In modern embedded systems, improving accuracy in branch prediction is one of the most crucial preoccupations. It’s well known that branch alias has become one of the most serious problem that affects the accuracy in 2-level adaptive predictor. In this paper, we propose a stack-based solution which can alleviate alias problem significantly and improve the accuracy in branch prediction. Our proposed solution extends 4 bits on the conventional PHT’s higher bits. Experiments are carried on Simple-scalar3.0e and the performance is verified by testing SPEC2006. The result shows that contrasting to the conventional prediction, the new proposed structure can achieve about 10.5% improvement on IPC on average with negligible extra hardware cost. | |||||||||
