Summary: | We can overcome performance limitation imposed by limited throughput of simulator-accelerator channel by introducing predictive channel access techniques. Predictive channel access technique minimizes the number of channel access by allowing execution of either simulation or acceleration domain and predicting responses of the other domain. While this method can bring a lot of performance gain when prediction accuracy is high, it can also result in bad performance when prediction accuracy is low. We call it performance deterioration of predictive method. This paper shows an adaptive predictive synchronization scheme where the "aggressiveness" of prediction is calibrated according to the environment. This eliminates performance deterioration and brings high performance with good prediction accuracies and moderate performance even when prediction accuracy is low. |
