A Novel Meta Predictor Design for Hybrid Branch Prediction
Recent systems have been paved the way for being high-performance due to the super-pipelining, dynamic scheduling and superscalar processor technologies. The performance of the system is greatly affected by the accuracy of the branch prediction because the overhead of each misprediction has grown due to greater number of instructions per cycle and the deepened pipeline. Hybrid branch prediction...

متن کاملLimits to Branch Prediction
Branch prediction is an important mechanism in modern microprocessor design. The focus of research in this area has been on designing new branch prediction schemes. In contrast, very few studies address the inherent limit of predictability of program themselves. Programs have an inherent limit of predictability due to the randomness of input data. Knowing the limit helps us to evaluate how good...
متن کاملLow-Power Branch Prediction
Low-power design has gained much attention recently, especially for computing on batterypowered equipments. Reducing BTB (branch target buffer) accesses is an effective way to reduce processor power consumption, since BTB consumes a significant portion of power in a processor. In this paper, we propose two approaches to reduce BTB accesses. The first approach expects the distance of every two d...
متن کاملNeuro-PPM Branch Prediction
Historically, Markovian predictors have been very successful in predicting branch outcomes. In this work we propose a hybrid scheme that employs two Prediction by Partial Matching (PPM) Markovian predictors, one that predicts based on local branch histories and one based on global branch histories. The two independent predictions are combined using a neural network. On the CBP-2 traces the prop...
