The HW is definitely powerfull enough to do so...

HPP is most likely too slow to do it at a speed close to what is needed :-( especially as it does not have anything that can simulate the memory while being fast...

Bit it would be interesting to think about what 4 or 5 instructions would be useful to speed things up significantly... and make it possible...

the 50G has around 2MB of ram space, which would easely fit in Prime (G2), so it should be more or less possible.
The main issue as far as I can tell is memory access (nibble read/write access) and nibble wise manipulations (in HEW and DCB)...

What if you waste memory by storing each nibble into a byte?
