The Xputer supporting the Mead-&-Conway Microchip Design Revolution:
DRC speed-up by a factor of 15.000 (see the PISA project).
amateurish introduction of the Systolic Array. The Xputer results from the
generalization of the sytolic array.
When we developped the anti-machine
paradigm as the counterpart of the von Neumann computer, we have been looking
for a prefix to replace "com" within the word "computer". Not
yet having a good
idea (do you have one?) we replaced "com" by "x" yielding "xputer".
The term "Xputer" does not mean "transputer",
which was a von Neumann machine, whereas the Xputer is
not - it is an anti-machine.
Why a different computing machine paradigm? It is the massive inefficiency of
the von Neumann paradigm. UC Berkeley professor C. V. "RAM" Ramamoorthy coined
the term "von Neumann
Syndrome" (also see
opening the discussion after listening to a keynote speech by Prof. Reiner Hartenstein.
Well known about this is "
Law" saying, that software is a gas which completely fills all available
storage space. Also see
Why we urgently must go heterogeneous:

A battle is on to claim supremacy in the next generation of computing.
Alliances are forming, battle plans are being forged, and armies are amassing.
Energy consumption: the enemy is power. The single limiting factor is energy consumption – for fastest processors increasing exponentially.
Efficiency is Everything. Von Neumann (vN) maximizes computational complexity. Silicon has become almost free.
However, Because of a lack of flexibility ASICs do not really solve these kinds of efficiency problems.
We urgently need a game changer providing incredible bandwidth and power efficiency.
We need multiple orders of magnitude in computational energy efficiency.
We must go heterogeneous by using von Neumann/FPGA machines.
Von-Neumann-only systems are inefficiently shuffling data back and force to and from DRAM.
We need low-latency connections between FPGA fabric and memory.
The problems are far from being solved. (Remark by Reiner: not quite that far by the twin paradigm approach using (vN) computers together with (non-vN-)
The next years will be interesting to watch.
