As a single chip computing cluster (multi
cores on one chip) there a many advantages.
The Cores
are asynchronous so this will average out the draw on the power
supply.
Each core
will have 4 to 6, 1+ Gigabit per second bi-directional serial interfaces
to it's neighboring CPU cores.
Each Gbps
serial will be addressable as a simple register read and write.
A patent is
being filed for a cooling and power delivery system to allow for
enormous clusters and ram on a very large chips.
In theory it
would be possible to build a single device running at 10 TeraFlops!
