Hi Dimitrios,
Open Virtual Platforms (www.ovpworld.org) provide a free (JIT)
simulator running at about 500Mips for the OR1K running on Windows,
there is also a gcc toolchain for Windows, take a look at the
following link. http://www.ovpworld2.org/download_OR1K.php
You will need to register to download the Simulator and Toolchains

Thx
Lee
