For a micro, see iAPX 432. It was considered over-complicated for its time but if CHERI catches on, perhaps far ahead of its time. Also interesting to me was the idea in Darek Mihocka's blog NO EXECUTE! about using emulation to implement advanced processor features rather than forcing everything through a one size fits all hardware policy. Of course emulation will always have a performance hit, but the concept is interesting. http://emulators.com/nx_toc.htm http://emulators.com/nx_toc.htm
