Low Power Consumption, Pipeline Stage Unification, Prediction Mechanism
This paper proposes a fine-grain-mode prediction for variable stage pipeline processor. Fine-grain controller adjusts the pipeline depth at every several tens of cycles and also predicts the suitable pipeline depth using a processor counter like as a cache hit counter or an each instruction counter. This method is used for variable stage pipeline (VSP) processor. A VSP processor varies in the pipeline depth dynamically according to workload. Based upon the workload the fine grain mode prediction unifies the pipeline stages. So, the power consumption reduces and increases its performance. A similar approach was proposed by Yao et al [3]. After 1 year the fine-grain control was proposed but their approach does not consider for the detailed mechanism to change pipeline depth with small penalty. To take advantage of fine-grain controlling of pipeline unification, it is essential to change pipeline depth without incurring a large penalty. This mode predictor is used for 7-stage pipeline processor. So that unification of the processor has been done and analyzing operation performed in the processor. This method is essential to change pipeline depth without incurring a large penalty.
