Isn't the general belief that many successful architectures that started out as RISC, and are still marketed as RISC, aren't actually very RISC-like at all any more? And, secondarily, that ARM is one of the ones that has stayed closest to its roots, unlike, e.g., POWER, SPARC and, well, most of the big hot UNIX workstation chips of the '90s? -- Liam Proven • Profile: http://lproven.livejournal.com/profile Email: lpro...@cix.co.uk • GMail/G+/Twitter/Flickr/Facebook: lproven MSN: lpro...@hotmail.com • Skype/AIM/Yahoo/LinkedIn: liamproven Cell/Mobiles: +44 7939-087884 (UK) • +420 702 829 053 (ČR)
