This repository contains an adapted version of the TAGE-SC-L branch predictor implementation of the Scarab simulator with interfaces for ChampSim, Gem5 and MBPlib.

The reason for having this repository is to have a correct and unique implementation that can be used in different simulators. For example, (at the moment of writing) Gem5 has a TAGE-SC-L implementation, but its speculative execution is incorrect, and its performance is that of a tournament predictor rather than a TAGE predictor.

We chose to start with the implementation in the Scarab simulator because it was mostly correct. We will make merge requests to the repository with the changes we performed.

You can see the available interfaces in the ifaces folder. Check the README of each interface to read about the installation process and other details.
