Introduction to gem5 gem5 is a modular discrete event driven computer system simulator platform. That means that: gem5's components can be rearranged, parameterized, extended or replaced easily to suit your needs.It simulates the passing of time as a series of discrete events.Its intended use is to simulate one or more computer systems in various ways.It's more than just a simulator; it's a simulator platform that lets you use as many of its premade components as you want to build up your own simulation system. gem5 is written primarily in C++ and python and most components are provided under a BSD style license. It can simulate a complete system with devices and an operating system in full system mode (FS mode) , or user space only programs where system services are provided directly by the simulator in systemcall emulation mode (SE mode) . There are varying levels of support for executing Alpha, ARM, MIPS, Power, SPARC, and 64 bit x86 binaries o...
