Evaluating Branch Predictor Configurations for a MIPS-like Pipeline
Konferensbidrag (offentliggjort, men ej förlagsutgivet), 2014
In this report, we investigate the implementation and efficiency of different types of branch predictors. A configurable VHDL model of a branch predictor unit, composed of a branch direction predictor and a branch target buffer, has been implemented. In order to make informed hardware decisions, different branch predictor configurations are simulated using the open source SimpleScalar simulator and the MiBench benchmark suite. The target architecture is a 7-stage 32-bit MIPS-based pipeline with two instruction fetch stages.
