Simulator for branch predictions
WebbSimulation of Branch Prediction. This project is a framework for simulating the Branch Prediction behavior of different branch prediction schemes. The framework provides for … WebbBranch Target Prediction • In addition to predicting the branch direction, we must also predict the branch target address • Branch PC indexes into a predictor table; indirect branches might be problematic • Most common indirect branch: return from a procedure – can be easily handled with a stack of return addresses 14
