I'd suggest that a Intel x86_64 of 2015 bears only a passing relationship to an IBM 360 of the 1960s. It is true that hardware design has been constrained by a weird constraint that no-one has investigated alternative architectures to the register/CPU that software people insist is the only way forward. With all the transistors available per mm² these days, it is about time we investigated alternate, implicitly parallel ways of working. Intel had a go a few years ago with various alternative dataflow based architectures, but they were told by the software people that they had no future because software inertia was more important than innovation. -- Russel. ============================================================================= Dr Russel Winder t: +44 20 7585 2200 voip: sip:russel.win...@ekiga.net 41 Buckmaster Road m: +44 7770 465 077 xmpp: rus...@winder.org.uk London SW11 1EN, UK w: www.russel.org.uk skype: russel_winder
