Hardware STG?

Hi, I am looking into starting a project on special hardware to run haskell - (or perhapse any lazy functional hardware)... If I go ahead the project will result in an open VHDL implementation. I would like to ask a couple of questions. Is there any point in doing this as the STG-machine is designed to make running haskell efficient on standard hardware? is TCode and the byte code used by GHCi the same? finally, does anyone know of any implementations that have already been attempted, and how successful were they? Any general comments on how worthwhile this might be? Regards, Keean Schupke Department of Electrical & Electronic Engineering, Imperial College London.
