Bryan,

Is this year the a2's 30th anniversary...?
An a2@1GHz==1000x faster, would be a nice way to celebrate it !!

but...

65816@xxxxxxx where have you seen it ? The last time I checked wdc they
had 20MHz parts.?
Even if you had the most optimized better available 65816 ip core I
think there's no way to sopc either as no current fpga will eat it
@1GHz.?
And, also, you would need a 2GHz memory bus for a 1GHz cpu clock !! (do
memory dimms this fast exist yet ?) or about 10 or so cpu wait cycles
(for a 100MHz memory bus) and then, it's of little (or no) use to run a
65xx cpu at 10X the memory bus speed...
:-(
