IIRC the StrongARM came out and caned it for performance, so it was dropped.
They couldn't use StrongARMs in it for some reason, perhaps it was a cache issue.
Maybe it could be resolved with some reengineering, I don't know. It would be really nice if that were the case.
But creating parallel processors seems to be quite tricky. I don't think a company would (or should) take any notice of a pertition unless it was backed up with cold hard cash.
