From EET.com: "A Chinese graduate student is offering freely
downloadable source code for the description of a
synthesizable processor core claimed to be compatible with the
ARM7 32-bit RISC processor developed by ARM Holdings plc ...
Although open-source or free hardware cores might seem
attractive, they are widely held by industry observers to be
difficult or impossible to use commercially because they lack
the legal and engineering support that a proprietary architecture usually includes. But
the academics, engineers and hobbyists continue to clone popular cores."
