ABPS - Advanced Branch Prediction Simulator:

- ABPS currently uses two kind of benchmarks for simulation purposes:
Stanford benchmarks (very helpful for didactic purposes - students);
SPEC 2000 benchmarks (more accurate, useful for a fine grained branch prediction study)

ABPS is a Detector

Detecting difficult to predict branches can be easily found with ABPS, in a highly configurable manner;
ABPS includes several detection schemes, based on:
-Local history (HrL);
-Global history (HrG);
-HrL + HrG;
-HrG + Path;
-HrL + HrG + Path.

ABPS is a Predictor.

Or, more exactly: a collection of predictors, fully configurable;
ABPS integrates two level predictors (GAg, GShare, PAg, PAp) and (state of the art) neural predictors (Simple perceptron, Fast-Path based percpetron)
