The purpose of the gem5 components library is to provide gem5 users a standard set of common and useful gem5 components pre-built to add to their experiments. The gem5 components library adopts a modular architecture design with the goal of components being easy to add and remove from designs, and extendable as needed. E.g., any Memory system should be interchangable with any other, and if not a helpful error messages should be raised. Examples of using the gem5 components library can be found in `configs/example/components-library`. Important Disclaimer: This is a pre-alpha release of the gem5 components library. The purpose of this release is to get some community feedback on this new component of gem5. Though some testing has been done, we expect regular fixes and improvements until this is in a stable state. The components library has been formatted with Python Black; typing has been checked with MyPy; and the library has been tested with the scripts in `configs/example/components-libary`. More rigorous tests are to be added in future revisions. More detailed documentation will appear in future revisions.

This is the gem5 simulator. The main website can be found at http://www.gem5.org A good starting point is http://www.gem5.org/about, and for more information about building the simulator and getting started please see http://www.gem5.org/documentation and http://www.gem5.org/documentation/learning_gem5/introduction. To build gem5, you will need the following software: g++ or clang, Python (gem5 links in the Python interpreter), SCons, SWIG, zlib, m4, and lastly protobuf if you want trace capture and playback support. Please see http://www.gem5.org/documentation/general_docs/building for more details concerning the minimum versions of the aforementioned tools. Once you have all dependencies resolved, type 'scons build/<ARCH>/gem5.opt' where ARCH is one of ARM, NULL, MIPS, POWER, SPARC, or X86. This will build an optimized version of the gem5 binary (gem5.opt) for the the specified architecture. See http://www.gem5.org/documentation/general_docs/building for more details and options. The basic source release includes these subdirectories: - configs: example simulation configuration scripts - ext: less-common external packages needed to build gem5 - src: source code of the gem5 simulator - system: source for some optional system software for simulated systems - tests: regression tests - util: useful utility programs and files To run full-system simulations, you will need compiled system firmware (console and PALcode for Alpha), kernel binaries and one or more disk images. If you have questions, please send mail to gem5-users@gem5.org Enjoy using gem5 and please share your modifications and extensions.
