Based on my experience with the Xilinx Spartan XC3S1000 (Digilent
Spartan-3 Board) I would guess that you could just about squeeze an
entire AppleCrate onto one. And the communications channel could be
much faster than that used on an AppleCrate. Don't know if anyone would
be interested in that or not. You could probably clock them faster than
an AppleCrate too, but maybe not much faster since you would probably
be time domain multiplexing the SRAM to provide enough memory to the
CPU cores.


Cool!  ;-)

Of course, with both on-chip and shared memory communication possible,
the entire networking premise of AppleCrate would be unneeded.  A much
closer coupling should be supported--closer to SMP.

It's fun to think about hi-tech approaches to lo-tech problems!  ;-)
