The term "Xputer" stands for the "Anti-machine" being the counterpart of the von Neumann paradigm since it's using data counters instead of a program counter.

Note the 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 here) when opening the discussion after listening to a keynote speech by Prof. Reiner Hartenstein. Well known about this is " Nathan's Law" saying, that software is a gas which completely fills all available storage space. Also see here and here.


Why we urgently must go heterogeneous: Keywords, abstracted by Reiner from:
“Cooling Off Accelerated Computing — Intel/Altera Attacks Memory Bottleneck — Abstract”
by Kevin Morris, May 25, 2016 - see: http://www.eejournal.com/archives/articles/20160525-coolingoff/

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-) Xputers.) The next years will be interesting to watch.
