That'll be the GPS MA31750 then (which is what I was asking). It is
the same processor I was using last time. I was just wondering whether
you'd gone down the road of dumping the GPS (well, GEC-Plessey
Semiconductors to us, I guess just Plessey to you) in favour of
something like the Performance Semiconductors implementation which was
a bit faster. We used the MA31750(H) I think - rated at 1.3MIPS at
10MHz. We were only allowed to run it at 9MHz though.

:-) They *were* talking about producing a Rad-Hard ARM processor last I heard.
