Gem5-AVX -------------------------------------------------------------------

This repo adds partial AVX2 and AVX-512 support to gem5. Key features:

• Supports many common instructions (passed the dense_mv test in avx_test).
• Most arithmetic instructions are broken into a single microop.
• No support for masking or broadcast. For more details, please refer to: https://seanzw.github.io/posts/gem5-avx/

Feel free to use and extend it. Please note that the code is not throughly tested, and almost certainly contains bugs. Use it at your own risk.

Original README ------------------------------------------------------------ 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//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.
