Aiming at instruction Likelihood of Criticality(LoC) of SPEC2000 programs under different clustered superscalar processor architectures,this paper proposes a design of static LoC key predictor.It discusses the instruction LoC,and finds that it has some characteristics,such as architecture-independent and dynamic-invariable.This paper uses this characteristics above to design the predictor.Simulation results show that when 1×8 cluster super-scalar processor uses the design,the program Instruction per Clock(IPC) average increases by 5.3%,and the perfor-mance is better than the dynamic LoC predictors.
