The gem5 Simulator: Version 20.0+

Understand

The open-source and community-supported gem5 simulator is one of the most popular tools for computer architecture research.

• This simulation infrastructure allows researchers to model modern computer hardware at the cycle level, and it has enough fidelity to boot unmodified Linux-based operating systems and run full applications for multiple architectures including x86, Arm, and RISC-V.
• The gem5 simulator has been under active development over the last nine years since the original gem5 release.
• In this time, there have been over 7500 commits to the codebase from over 250 unique contributors which have improved the simulator by adding new features, fixing bugs, and increasing the code quality.
