The transputer boards that I saw uses ARRAYs of trasputers (that's the use of
these chips) so each chip can process a thing in parallel with the rest. The
good part of the trasputers is the optimized communication, simple chips can
use 20 Mb and can be communicated with 4 chips (to create the array). So the
idea is parallel execution.
