Abstract:

Value prediction is one of the effective techniques that increase ILP by speculative execution, but its hardware cost and power consumption are two ma  in limitations. This paper focuses on studying the main sources of power consumption during the use of value prediction, and compare several value prediction models from the angle of power consumption.

Key words: ILP, VP, value prediction, power consumption, IPC, Last prediction, Stride prediction, Cont ext prediction
