I wonder if it's really two cpus (Score 1)

I strikes me that the Crusoe could have have effectively two
complete cpu's inside. One to do code morphing / JIT, the
other to do VLIW processing. They could have entirely
different instruction sets.
The jit cpu could be working independantly of the VLIW cpu,
without 'stealing' it's cycles, and feeding it.
The VLIW cpu may not need external bus connexions.
Otherwise I'm puzzled about how you you would get the
performance claimed.
