Regarding PPC capability. Isn't it more efficient to use a Xilinx Virtex-4 FX or similar with builtin PPC ..?
(which can run ordinary m68k minimig on the standard logic matrix)

Is there anything in particular that makes it worthwhile to persue DCE rather than reverse engineer existing hw/sw ..?

Is there a standard spec for Amiga PPC accelerators, or a defacto one?, otherwise maybe one have more freedom in choosing the functionality.
