We are so used to von neumann architecture and say a register machine like the x86. (Also with   programming languages built for those machines x86 assembly, C, etc)  Is that approach to computing completely separate from a language and system like haskell?What would a machine look like that was based functional programming paradigms look like? and  one not running on a register or stack machine.This article is relevant to my question:http://www.stanford.edu/class/cs242/readings/backus.pdf
Are register based machines on von neumann architecture diametrically opposed to functional programming style?

Many hardware designs for executing functional programs have been proposed:The Lisp MachineSteele and Sussman's Scheme chip designThe Reduceron, by Naylor and Runcimanand more (lots are cited in the Reduceron papers).
