Merging Path, Global and Local Indexing in Perceptron Branch Prediction
-> If we want more single-thread performance,
we have to go for efficiency!
Main Problems in Branch Prediction:
Addressing these two points
Normal pipelined perceptron
Ahead pipelined perceptron
Impact of ahead-pipelining on accuracy
Precomputing a local history perceptron
Impact of adding local history
We have been here before!
