Welcome to our wiki

This wiki site contains all the information regarding the CAVA-LINUX full-system emulator. CAVA-LINUX is a full-system emulator running a yet-simple but extensible RISC ISA running Linux and uClibc. We envision CAVA-LINUX as a useful research tool for hardare-software co-design of computer systems.

Warning: Please notice that this wiki is still under development. You are encouraged to help improve it!

Get started

The sources of CAVA-LINUX can be found in:

https://bitbucket.org/isvtlinux/isvt-linux

You can checkout the repository using Mercurial:
